Chapter 1 —School Mathematics in a Changing World Chapter Overview In this chapter, the student is asked to examine what mathematics is and what determines the mathematics being taught. A brief historical perspective of the mathematics curriculum is discussed with a clear presentation of the underlying Principles developed by the National Council of Teachers of Mathematics [NCTM]. Three general factors (needs) are presented as influences on the mathematics curriculum. The chapter concludes with a discussion of resources teachers can use to learn more about teaching mathematics.

Student Objectives After reading the chapter, the students will be able to: 1.

Describe five views of mathematics.

2.

Summarize three needs that influence the mathematics curriculum.

3.

Summarize recommendations from NCTM’s six underlying Principles of school mathematics.

4.

Identify resources for learning more about mathematics teaching.

Key Vocabulary For this chapter, many of the key terms involve connections to names of persons and organizations. Students may have encountered these names and terms in earlier courses with others being specifically tied to the mathematics subject area.

Instructor’s Resource Guide, Chapter 1 Sandi Cooper |3 Student Textbook Activities 1.

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and on PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2.

Involve students in a discussion about what mathematics is, what it has been and what it should be. These questions are central to the discussion of the mathematics curriculum and the forces affecting its form. Most prospective teachers and elementary children, based on their past experiences, may tend to view mathematics as arithmetic.

Mathematics is often viewed as a quest for the "correct answer". Have students examine Figure 1-1, Vision of the mathematics content distribution through the grade levels and have them relate this to their own school experiences.

3.

PPT Slide #3, What is Mathematics? describes mathematics in five different ways - as discussed in the text. You may want to start by having students compile a list of words they associate with mathematics. Using these, lead the discussion to the five views of mathematics and have the class brainstorm examples that fit within each definition.

4.

PPT Slides #6-12, Principles for School Mathematics, provides the five underlying principles of school mathematics as outlined in NCTM’s Principles and Standards for School Mathematics. These may also be found in the text on pages 6-7. Encourage students to discuss each principle and its implications for them as future elementary teachers.

5.

In small groups, have students develop a vertical timeline (1900, 1910...1990, 2000).

Have each group locate key items from chapter 1 and place them on the timeline.

Discuss the results as a class. A suggested timeline follows which may be cut apart for groups to locate in the text. Follow up with a discussion of PPT Slides #13-14, Major Trends in School Mathematics.

Starter #2: Brainstorm what classroom teachers can do as they prepare to change the elementary mathematics curriculum.

Student Supplemental Activities 1.

.S o n s

Have students complete an introductory survey on the first day of class. These surveys may be returned to students on the last day of class and changes that occurred may be discussed. The survey may include items such as: • Math is...

• When it comes to math, I feel...

• I think my math ability is...

• Elementary math should be...

• It is most important that elementary math students learn...

• Name one thing you remember from your math classes in elementary school.

• Describe what you hope to learn from this course.

• How I feel about teaching mathematics is…

Instructor’s Resource Guide, Chapter 1 Sandi Cooper |5 2.

As students introduce themselves, have them share information from one of their survey items such as a memory (good or bad) from their math classes in elementary school.

Discuss implications for their future teaching of mathematics or preview how the items discussed will be addressed in the course.

3.

Present to the students a list of myths about mathematics as presented in the article by Martha L. Frank, What Myths about Mathematics are Held and Conveyed by Teachers?

(Arithmetic Teacher, 37(5): 10-12 - Jan 1990). Allow them to discuss in small groups and then share as a whole group. Discuss how certain beliefs might be conveyed unintentionally through instruction.

4.

Start a collection of magazine and newspaper articles related to mathematics education, student performance, the accountability or reform movement. For example, titles such as "Study: U.S. Students poor in math and science", or "U.S. Students Math Scores Up"...

Divide students into groups to discuss the articles and then summarize results for the class. Start a display and encourage students to bring in articles throughout the course.

5.

Have the class build "get acquainted" line plots or graphs using materials such as grid paper, Post-It Notes®, links or paper clips, or connecting cubes (See Figures 17-3 and 17-4 in Chapter 17). Prior to collecting the data, have students discuss and predict the outcomes. You may have students estimate the number of candies in a jar or respond to questions such as: • How do you feel about teaching mathematics? Stack your cube under the happy face, so-so face, or sad face.

• What grade do you most want to teach? Hang your link on your favorite grade.

• What month were you born? Place your Post-it Note® under the correct month.

• What is the first letter of your first name? Mark an x on the line plot above the letter.

• How many letters in your first name? Estimate the average number of letters in first names in this class.

Examine the variety of ways elementary students can easily display data. Have students brainstorm other questions which could be used as get acquainted mathematics activities with elementary students such as name your favorite color, measure your height in centimeters...

6.

Have students work in groups to discuss items from Things to do: From What You've Read, Things to do: Going Beyond this Book (page 11).

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |1

Chapter 2 —Helping Children Learn Mathematics with Understanding What This Chapter Is About A survey of teachers asked, “How do children learn?” Although many teachers provided insightful responses to this difficult yet important question, almost half of the teachers said, “I have not thought about it.” This chapter is designed to focus attention on a few critical things known about how children learn mathematics. Ways to support diverse learners are presented.

Key research findings on cognitive development are consolidated and discussed in an effort to translate relevant ideas and their implications for instruction into a form that is meaningful and understandable. Behaviorism and constructivism are introduced. Four recommendations for helping children make sense of mathematics are developed and presented.

Student Objectives After reading the chapter, the students will be able to: 1.

Summarize five ways to support the diverse learners in our mathematics classrooms.

2.

Differentiate between procedural and conceptual knowledge.

3.

Differentiate between behaviorist and constructivist learning theories.

4.

List four common observations about how children learn as characterized by Piaget, Bruner, and Dienes and differentiate among them. Summarize recommendations for helping children make sense of mathematics as based on these observations about how children learn.

Key Vocabulary A number of key terms related to learning, mathematics learning in particular, are used in this chapter. Some of them build upon concepts learned earlier in educational psychology but many of them are unique to mathematics.

Behaviorism Constructivism zone of proximal development procedural knowledge conceptual knowledge multiembodiment metacognition .S o n s

mathematics anxiety learned helplessness retention cognitive development physical development social development

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |2 Supplemental Lecture Topics 1.

Discuss some current trends in education that have behaviorism as a base such as drill and practice curricula or instructional materials, and instructional design work by Gagne.

2.

Provide additional information about constructivist work in mathematics education being conducted by researchers such as Kamii, Fosnot, and Cobb. In Beyond Classical Pedagogy: Teaching Elementary School Mathematics, share with students research from three disciplinary perspectives. In What’s Happening in Math Class? Vol. I, share essays written by constructivist teachers. Sample constructivist activities may be found in About Teaching Mathematics, 2nd. Ed by Marilyn Burns and available from Math Solutions.

3.

Provide additional information about Piaget, Bruner, and Dienes and their theories. See the end of book reference list for books they have authored.

4.

Provide additional information about children’s cognitive, social, and physical development.

5.

Discuss procedural and conceptual understanding in greater detail. Excellent sources by Hiebert are included in the end of book resources. In addition, see Making Sense listed in additional resources.

6.

Currently, most preservice and inservice students did not learn elementary mathematics with manipulatives. Provide additional information about what research says about the use of manipulatives and recommendations for teaching with manipulatives. A classic source of information is "Considerations for teachers using manipulative materials" by Robert Reys in Arithmetic Teacher, December, 1971. In this article he defines manipulatives, provides a rational for the use of manipulatives, discusses selection criteria, and gives do's and don'ts for use.

7.

Students also need to become familiar with commercial manipulatives that are available for teaching elementary mathematics. While it is assumed that these will be included throughout the semester, the study of chapter two would be an appropriate time to introduce to students several of the more common commercial manipulatives. Some states, such as Texas, have lists of recommended manipulatives for each elementary grade and those could be duplicated for students.

Manipulatives which might be introduced: attribute blocks, base ten blocks, fraction and decimal models, geoboards, interlocking centimeter cubes, interlocking counting cubes such as unifix or multilink cubes, pattern blocks, tangrams, and pentominoes. A good resource is The Super Source from Cuisenaire Company. (See additional resources.)

Bring an assortment of catalogs from which manipulatives may be ordered (and websites) and as you display each item, let students handle it and look up the price. Follow up with a discussion of ways to cut costs such as the use of overhead versions for demonstration,

.S o n s

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |3 purchasing for small groups rather than individuals, and alternatives which may be constructed by the teacher or students (see Appendix B in text).

8.

Provide additional information about diverse learners and the teaching of mathematics.

The article by Fennema et al. in the chapter two resources would be a useful source as well as the 1997 NCTM Yearbook-Multicultural and Gender Equity in the Mathematics Classroom, the Changing the Faces of Mathematics series from NCTM, Fiesty Females: Inspiring Girls to Think Mathematically available from Heinemann, and How to Encourage Girls in Math and Science: Strategies for Parents and Educators available from Dale Seymour Publications.

9.

Discuss metacognition in greater detail. A classic article by Garafalo in the May 1987 issue of the Arithmetic Teacher is a good place to start. In addition, Garafalo and Lester's article, Metacognition, cognitive monitoring, and mathematical performance, may be found in the 1985 (issue 3) Journal for Research in Mathematics Education and provides information concerning metacognitive knowledge of person, task, and strategy and metacognitive self-regulation.

10.

Discuss the six standards for teaching mathematics found in NCTM's Professional Standards for Teaching Mathematics, 1991 (See NCTM.org). You could organize the discussion by using a “jigsaw” method, where students are in “home” groups of six and each student is assigned specific standard to prepare. After they have read their standard individually, they meet with their “expert” group to discuss the assigned standard in more detail (expert group refers to all students with the same standard). Then, students join their “home” group to allow each to share the standard they “studied.” You may also use lesson Snapshot video clips found throughout this text as examples to follow this discussion.

11.

Provide more information about math anxiety. A couple of good sources include Math: Facing an American Phobia by Marilyn Burns, available from Math Solutions and Overcoming Math Anxiety (available from W.W. Norton and Company) and Succeed with Math: Every Student’s Guide to Conquering Math Anxiety (available from The College Board) both by Shelia Tobias.

12.

Provide more information about teaching mathematics to young children. Good resources include The Young Child and Mathematics by Juanita V. Copley (Available from NCTM) and Growing Mathematical Ideas in Kindergarten by Linda Schulman, Dacey and Rebeka Eston (Available from Math Solutions).

Student Textbook Activities 1.

.S o n s

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and on PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |4 2.

Have students review the Chapter 2 Snapshot of a Lesson (pp. 12-13). Discuss how this lesson illustrates some of the shifts in classroom environment (Table 2-1, p. 15).

3.

Using PPT Slide #3, How Can we Support the Diverse Learners in our Classrooms?, discuss the five strategies a teacher can use in his/her math classroom. Talk about potential benefits and challenges that come when teaching classrooms of diverse learners.

4.

Use PPT Slides 4-7, Procedural and Conceptual Knowledge to review the definition of the two terms. Then one at a time, display the provided examples of student knowledge and have the class classify them as procedural or conceptual.

5.

Use PPT Slides #8-12, Behaviorism and Constructivism, to allow students to compare and contrast the behaviorist and constructivist theories of learning. Or have them fill in a 3-column chart with headings Behaviorism, Constructivism, and Both.

Possible responses may include: Behaviorism-behavior may be shaped with reinforcement, direct instruction and drill and practice are necessary, specific goals or objectives-often simple and short term are identified for teachers and students, teachers develop task analysis as skills are learned in a specific order Constructivism-knowledge is actively invented by the learner, new knowledge is integrated into existing mental structures, learning is a social process, exploration and discovery are necessary Both-are evident in today's textbooks

6.

Use Tables 2-2 and 2-3, Characteristics of Learners, and have small groups think of other suggestions for teachers.

7.

Have students work through In the Classroom 2-1, Different Kinds of Four-Sided Figures. Discuss how this activity can be used to determine students’ conceptual understanding.

8.

Have students use interlocking cubes to complete In the Classroom 2-2, Patterns with Blocks. Discuss with students how the completion of this activity could not only encourage problem solving and exploration but also lead to the discovery of the formula for volume of a box (right prism). You may also want to show a clip from the video, Mathematics With Manipulatives: Six Models that shows students filling boxes with cubes.

Student Supplemental Activities 1.

.S o n s

Bring in sample goals and assessment items being used for mathematics in your state.

Have students examine them and determine if they seem to be based on behaviorism, constructivism, or some combination.

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |5 2.

Have students examine and compare elementary texts from the late 1970s and the early 2000s. Encourage students to identify behaviorist and constructivist influences. Discuss how 1970s edition was published during the "back to the basics" era. Have students answer the question, "Are textbooks less behavioristic in the 2000s than the 1970s?"

3.

Using those same textbooks mentioned in supplemental activity 2, have students select one lesson and identify the conceptual and procedural knowledge to be learned. Have students discuss whether texts seem to emphasize one type of knowledge over another.

4.

Assign groups of students to research and report on persons who have been prominent influences on mathematics curriculum such as Piaget, Bruner, and Dienes.

5.

Choose a mathematical topic and demonstrate how it could be taught from a behaviorist or a constructivist point of view. For example, in the book, About Teaching Mathematics 2nd edition, by Marilyn Burns, an excellent example of a constructivist lesson is provided on the relationship between a circle's circumference and diameter. After students have experienced the two lessons, have them discuss the pros and cons of each approach.

6.

To further illustrate the concept of multi-embodiment, bring in a variety of fraction models for parts of a whole such as fraction pies and fraction strips and parts of a set such as color tiles. Discuss the importance of multi-embodiment and have students brainstorm other materials that could be used to illustrate examples and non-examples for fraction ideas.

7.

PPT Slides #19-21 shows another example of a powerful formula that can be developed naturally with pictures. These pictures encourage students to build on what they know about finding the area of rectangles and apply it to find the sum of the first n counting numbers.

Materials: PPT Slides #19-21, grid paper (1/2 inch or larger, see Appendix B), scissors • Share as a class in considering the first two specific examples pictured on the transparency.

• Assign students to work either individually, in pairs, or small groups to use grid paper and scissors to form staircases for the first 8 counting numbers, first 10 counting numbers, etc.

• Have each group report on their findings, or have them mount their evidence on a large sheet of butcher paper or bulletin board to allow the results to be viewed easily.

• Consider the general case for the sum of the first n counting numbers as illustrated on the transparency. The staircases cut from grid paper should serve to convince any skeptics that 1 + 2 + 3 + 4 + . . . . . + n = n (n+1)/2 .

This problem involves students in problem solving, provides the opportunities for many connections, and illustrates several principles for learning mathematics discussed in this chapter. Encourage students to write about and discuss their

.S o n s

Instructor’s Resource Guide, Chapter 2 Sandi Cooper |6 learning experience. It would also be meaningful to have students examine their metacognitions during the experience.

8.

Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book, and Annotated Resources. (pp. 30-31)

9.

The Book Nook for Children, found on pages 31 of the text, provides some children's literature that may be used. Read some of these books and have students develop lessons to go with particular titles. Discuss how children's literature provides a context for developing conceptual understanding or examining historic figures.

10.

Using the References at the end of the chapter, have students locate additional information on topics that interest them such as constructivism, human development or teaching recommendations.

Instructor’s Resource Guide, Chapter 3 Sandi Cooper |1

Chapter 3— Planning for and Teaching Diverse Learners Chapter Overview The importance of planning and instruction is the focus of the chapter, opening with a discussion of questions teachers should ask before planning begins. These include: Do I understand the mathematics I am teaching? Where are my students developmentally? What do my students know? What kinds of tasks will I give my students? How will I encourage my students to communicate? What kinds of questions will I ask? What materials will we use? Reasons for planning and the different levels of planning - daily, unit, year-long - are outlined. Basic components and approaches to a lesson plan are reviewed for the investigative plan, direct instruction plan, and exploration plan. Suggestions for planning to meet the needs of students from other cultures, students who are learning English, and students with special needs are included. Other planning and assessment considerations are summarized in the chapter material.

Student Objectives After reading the chapter, the students will be able to: 1.

Summarize six questions teachers ask before planning lessons. (These include: Do I understand the mathematics I am teaching? Where are my students developmentally?

What do my students know? What kinds of tasks will I give my students? How will I encourage my students to communicate? What kinds of questions will I ask? What materials will we use?)

2.

Differentiate among levels of planning and three types of lessons (investigative, direct instruction, and exploration) as well as discuss why it is also important to assess and reflect after teaching.

3.

Summarize recommendations for meeting the needs of all students during mathematics lessons.

6.

Continue a discussion concerning the role of manipulatives in mathematics lessons. Use PPT Slide #8, Manipulatives, to summarize points made in the text. Have students brainstorm ideas for accomplishing items 2-4.

7.

Discuss each of the three levels of planning: year, unit, day. Use PPT Slides #11-14, Levels of Planning, to provide illustrations for year and unit planning. Specific observations concerning the planning examples follow.

Year: Examine text, district curriculum guide, state requirements, current research and recommendations (ex. NCTM Principles and Standards) and the children's needs.

Identify the units or topics, the sequence of units and the amount of time spent on each.

The article, The Mathematics Textbook: How Can it Serve the Standards? by Rosemary Schmalz, may be found in the February 1994 Arithmetic Teacher. She provides a description of how the teacher can adjust the text sequence to include more new material when planning.

Discussion for PPT Slide #11 example: • The teacher assessed the class and determined that most of the students had mastered text Ch. 1-Place Value and text Ch. 2-addition and subtraction so he chooses to begin with Chapter 3-multiplication, including reviews of Ch 1,2 content while in Ch. 3. Three to four weeks are saved and can be used as needed later in the year. Problem solving strategies, estimation, and mental computation will also be included in daily warm-up activities throughout the year.

• The teacher also identified required topics from the district and state curriculum guides.

The district had an additional computer unit to be completed by all sixth graders and the grade level team planned a mini project around the fall election. State curriculum topics had to be included prior to the state assessment in February so Ch. 9,10 and part of Ch. 7 were moved up. Since the state assessment does not require multiplying fractions and statistics but the district curriculum does, a section of Ch. 7 and Ch. 11 were taught after the state assessments were completed.

• The teacher also knew that division and fractions were the most difficult for students and heavily emphasized on the state assessment so he scheduled the most days for those two units. Following the NCTM Standards recommendations, he plans to emphasize understanding with lots of hands on explorations. Measurement and geometry were lighter topics and provided a break from the computational instruction. They were also good topics to study during December when holiday activities can be integrated. He

.S o n s

Instructor’s Resource Guide, Chapter 3 Sandi Cooper |5

decided to teach metric and customary measurement together although the text separated them into different chapters.

Unit: Identify specific objectives, sequence of objectives, the amount of time spent on each objective and how student knowledge will be assessed. It would also be appropriate to discuss the potential of interdisciplinary planning in elementary classrooms.

Discussion for PPT Slides #13-14 example: The teacher decided to use the text as a resource for the first two days of the unit while providing information about collecting, displaying, and interpreting data. He will use a concrete model and a real life application when introducing mean, median, mode and range. For the rest of the unit, students will work in small groups and apply the skills to a real, meaningful project. Computers will be used to collect and display the data. Groups will present and display their findings. On the last day, students will complete journal entries, update their portfolios and complete a performance assessment.

Day: Identify specific objectives, identify how students will be grouped, the types of learning activities to be included, the materials to be used, amount of time spent and how student progress will be evaluated. PPT Slides #15-16 may be reviewed. Using the lesson plan format students will be required to follow, a lesson plan from the sample chapter 11 may be developed and discussed.

8.

Review Masters PPT Slides #4-6. Then starting with a textbook lesson, demonstrate how it can be used as a base for developing a lesson plan. As examples, use PPT Slide #17 to create an investigative lesson plan, PPT Slide #18 to create a direct instruction lesson plan, and PPT Slide #19 to create an exploration lesson plan.

9.

Use PPT Slide #24, Adaptations, to discuss how a lesson plan may be geared up or down to meet the needs of all students. Provide students with a lesson plan (You might use the direct instruction lesson on page 51 of the text.) and challenge them to create adaptations for low achievers, high achievers, and English language learners. Examples of adaptations are provided in Figure 3-9 on page 57.

10.

Review PPT Slides #20-21: Teaching English Language Learners, and PPT Slides #2223: Potential Barriers for Students with Special Needs. For each key idea, brainstorm examples.

Student Supplemental Activities 1.

.S o n s

Have students examine several current textbook series (traditional and standards-based).

Have them identify evidence of the NCTM Principles and Standards recommendations, the use of manipulatives and technology, the use questioning and communication, the use of adaptations, and assessment techniques.

Instructor’s Resource Guide, Chapter 3 Sandi Cooper |6

2.

Elementary students are expected to communicate and reason about mathematics. For this to occur, preservice elementary teachers need to have experiences that involve them in mathematics in a similar fashion. The following problem provides an opportunity for students to verbalize their understandings and reasoning about one of many patterns to be found in the hundred board.

Materials: PPT Slides #26-27: Find a Pattern, copies of hundred boards (Appendix B), color tiles, calculators, copy of hundred board to display.

• Start by making sure that students have a hundred board to use and access to a calculator for computing the averages necessary.

• Share the problem and steps for establishing a pattern using the overhead transparency of the problem.

• Allow time for students to work and share together. Take advantage of the chance to observe your students as they work.

• Bring the group together to discuss the pattern that was observed and share their understandings of why this pattern is occurring. Encourage their participation by communicating to others their understanding of the situation using words, symbols, or pictures/models. Use of an hundred board transparency may be helpful as students provide explanations.

3.

Use PPT Slides #9-10: Educational Software to review types of software. Have students review computer software that could be used in teaching mathematics. Include at least one example each for the 5 software types: drill and practice, simulation, tutorial, problem solving, and game. Discuss how higher-level thinking can be incorporated.

Working in this setting provides prospective teachers with experience as learners being taught in the way they are to teach. Have them turn in a written review in which they discuss the pros and cons of one of the pieces reviewed.

4.

Have students participate in a small group learning activity that utilizes the "jigsaw" strategy. Sample activities may be found in resource books such as Get It Together: Math Problems for Groups by Tim Erickson, published by the Lawrence Hall of Science.

After completing the activity, debrief and allow students to discuss their impressions.

5.

Provide each small group with the teacher's guide from a textbook series with a particular topic or lesson marked. Have the group plan a lesson based on what they have learned from this and earlier chapters. How could problem solving, technology, and manipulative materials be incorporated into the topic they are considering? How can the lesson reflect the recommendations of the NCTM Teaching Standards? Have them write the lesson using PPT Slides #17-19 as templates. Allow time for the groups to share their ideas for approaching the variety of topics selected.

6.

Have students examine samples of state and district curriculum guides and textbook scope and sequence charts. Have students outline a plan for a year or a unit plan similar to the one provided on PPT Slides #12-14.

.S o n s

Instructor’s Resource Guide, Chapter 3 Sandi Cooper |7

7.

Allow students to examine lesson plans written in various formats with varying levels of detail. For example, provide some traditional textbook lessons, standards-based textbook lessons, teacher plan book lessons, commercial lessons such as the ones found in books from Math Solutions. Have students discuss in groups the pros and cons of each lesson plan type.

8.

Invite a practicing teacher or administrator to class to talk about lesson planning. Or have students interview a teacher or administrator. Discuss the types of plans that are required, the level of detail required, the time spent on planning, etc.

9.

Locate the textbook pages from which the sample lesson plans, Figures 3-3, 3-4, 3-5, and 3-6 were created. Allow students to compare the text pages with the lesson plans and discuss critical features.

10.

The Math Links in this chapter provide students with additional resources for this chapter about communicating, manipulatives, and English Language Learners. In class, or as an outside assignment, have students explore these web sites.

11.

The Book Nook for Children, found in the text on pages 60 lists several teacher resource books for using children’s literature with mathematics. Bring several of these books to class and have students brainstorm ideas that could be used in a math lesson.

12.

Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book. (pp. 59-60)

13.

Using the References list at the end of the chapter, have students locate additional information on topics which interest them such as cooperative learning and understanding mathematics.

14.

Current elementary textbooks may also be used to show examples of a spiral curriculum.

Have various small groups choose specific content, such as place value or multiplication of whole numbers, and examine how the level of difficulty increases as the grade level increases. Discuss the pros and cons of a spiral curriculum mentioned in the text.

15.

One way for students to begin to understand how children learn mathematics is to observe children in action. Have your students pose a problem to an individual child or small group. One interesting approach would be to vary the use or nonuse of manipulative materials as children attempt to find a solution to the situation presented.

Chapter 4— Assessment: Enhanced Learning and Teaching What This Chapter Is About This chapter looks at student assessment as an integral part of teaching. Recommendations from NCTM's Assessment Principle and Assessment Standards for School Mathematics are highlighted. Assessment of learning (summative) and assessment for learning (formative) are discussed and the four phases of assessment are illustrated. Various ways of gathering evidence, recording, analyzing, and communicating information from assessments are shared. Stressed is the importance of collecting sufficient data to be used in positive ways to support students learning, modify instruction, and inform parents.

Student Objectives After reading the chapter, the students will be able to: 1.

Distinguish between and provide examples of assessment of learning (summative) and assessment for learning (formative).

2.

Summarize the NCTM Assessment Standards recommendations and shifts in student assessment.

3.

Summarize methods of gathering evidence and making judgments about student learning.

4.

Summarize methods of keeping records and communicating about assessments.

5.

Identify three groups with which the teacher communicates.

Key Vocabulary The chapter stresses the importance of using appropriate forms of assessment and discusses each of the terms below. It is important that students understand the different possibilities and be able to use the correct terms when discussing assessment. observation rubric questioning performance indicator interviewing peer assessment performance tasks Assessment Principle self-assessments checklists work samples class records portfolios student files writings teacher-designed written tests Assessment Standards for School Mathematics .S o n s

The Assessment Standards for School Mathematics (in additional resources and PPT Slides #9-11) provides information about NCTM's recommendations concerning assessment.

2.

Display and discuss assessment instruments and techniques used in your state's assessment program. Invite a practicing teacher to discuss implications for instruction.

3.

Discuss specific assessment techniques and display student work samples. The NCTM 1993 Yearbook, Assessment in the Mathematics Classroom, Exploring Classroom Assessment in Mathematics, Learning from Assessment: Tools for Examining Assessment through Standards, Mathematics Assessment: Cases and Discussion Questions for Grades K-5, Mathematics Assessment Sampler, and Measure for Measure: Using Portfolios in K-8 Mathematics are good sources.

4.

Display and discuss specific examples of alternative assessment instruments.

Mathematics Assessment: Myths, Models, Good Questions, and Practical Suggestions, (in additional resources) provides great examples.

5.

Display and discuss PPT Slides #22-26. They are work samples taken from children in grades three and four. All of the children were asked to solve the following problem: Nineteen children are going on a field trip. Five children can ride in each car. How many cars will be needed to get all 19 children? Problem source: Models of problem solving processes by Carpenter et al. (See additional resources.) The problems were read to the students and reread as many times as needed. The samples are intended to show the variety of approaches children will use when they are not restricted to a particular method. They also show that children are often intuitively able to solve problems with manipulatives or drawings for which they have not had formal instruction. Specific observations concerning each sample follow: PPT #22 Alex used color tiles to successfully solve the problem. He does not attempt to write a division equation.

PPT #23 Ben successfully draws a picture, then uses the division symbol in an equation. He knows the answer to the problem is four but does not consider the remainder.

PPT #24 Carl uses repeated subtraction to successfully solve the problem. He does not consider the remainder.

PPT #25 Andrea successfully solves the problem. She uses tally marks. First, she places 4 in each car, then corrects and uses five. She places the writes the symbols in the format of a subtraction problem.

PPT #26 Amy used color tiles to successfully solve the problem, then sketched this solution. She notes there will be a remainder of one seat left.

Encourage students to share observations about the work samples and what the children know. Students could also use the holistic scoring scale on p. 76 or the analytic scoring scale on page 75 to evaluate the work samples.

Student Supplemental Activities 1.

Collect a variety of actual assessment instruments from a variety of sources. Give each small group one or two instruments to discuss in light of their experiences and topics brought up for consideration in this and earlier chapters. Classify them as whether they could be used for assessment for learning or assessment of learning. Are there items they think are valuable for assessing the understanding of children? Why? Are there items that are not useful? Why? How could items be improved? (See additional resources for good sources of instruments.)

2.

Have students read the articles, Learning to question: categories of questioning used by preservice teachers during diagnostic mathematics interviews by Moyer & Milewicz (2002) and Interviews: a window to students’ conceptual knowledge of the operations by Huinker (1993). Lead a group discussion of important information from these articles, especially as a preparation for conducting interviews with children.

3.

Have students prepare a basic plan for conducting an interview. Place students in pairs to role play the interview process based on the written outline prepared. If students are involved in a field experience, have them audiotape or videotape their interview with a child. After either experience, have students reflect on their interview. Were there questions they should have included? Were there responses that were unexpected? How would they refine the interview outline and questions in preparation for the next interview experience? In the Classroom 4-1 may be used as an example.

Chapter 5 — Processes of Doing Mathematics What This Chapter Is About This chapter provides an overview of NCTM’s five Process Standards: Problem Solving, Reasoning and Proof, Communication, Connections, and Representations. Problem solving is a process central to the mathematics curriculum. Problems should challenge and engage students in learning. Reasoning involves justifying mathematical conjectures. Communication allows children to share ideas and deepen their knowledge. Connections are made among mathematical ideas, symbols and procedures, and contexts outside mathematics.

Student Objectives After reading the chapter, the students will be able to: 1. Summarize NCTM’s five Process Standards.

2. Describe the eight mathematical practices highlighted in the Common Core State Standards Initiative.

3. Describe how teaching mathematics through problem solving is different from simply teaching students to solve problems.

Key Vocabulary The Process Standards and problem solving are important parts of the mathematics curriculum.

Students should understand what a problem is and be aware of the different strategies and approaches used in problem solving.

NCTM Process Standards problem solving reasoning and proof conjecture communication connections representation

.S o n s

Instructor’s Resource Guide, Chapter 5 Sandi Cooper |2 Supplemental Lecture Topics 1.

Some NCTM yearbooks provide excellent information on the process standards.

Connecting Mathematics across the Curriculum (1995), Communication in Mathematics, K-12 and Beyond (1996), Developing Mathematical Reasoning in Grades K-12, (1999) and The Roles of Representation in School Mathematics (2001), are good sources of information. Two other resources include Mathematical Reasoning: Analogies, Metaphors, and Images and Language and Communication in the Mathematics Classroom (see additional resources).

2.

The classic chapter, Developing Understanding in Mathematics via Problem Solving, by Schroeder and Lester (listed under additional resources) provides an interesting discussion of three approaches to teaching problem solving. Discuss the three approaches (teaching about, for, and via problem solving) and demonstrate examples of the three approaches. For example: Teaching a specific problem-solving strategy would be an example of teaching about problem solving. Teaching how to multiply, then providing problems involving multiplication would be an example of teaching for problem solving. The banquet table problem, found in Mouse & Elephant, The Middle Grades Mathematics Project, (additional resources) would be an example of teaching via problem solving.

3.

Provide additional examples of supporting children’s talk by using resources such as Talking Mathematics: Supporting Children’s Voices (book and video) and Let’s Talk Math.

4.

Provide additional information about Cognitively Guided Instruction. The book, Children’s Mathematics: Cognitively Guided Instruction (additional resources) and accompanying CD provide insight into teachers and children implementing the strategy.

5.

Preservice teachers may have the misconception that young children aren’t able to do problem solving and reasoning. Share examples from Little Kids-Powerful Problem Solvers, Math is Language Too, Show and Tell (see additional resources).

6.

Show additional video clips from the text’s Snapshot of a Lessons or from video resources found under Additional Resources. Discuss the process standards being applied.

Student Textbook Activities 1.

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2.

Have students review the Chapter 5 Snapshot of a Lesson. Have them identify all of the different process standards that were used.

.S o n s

Instructor’s Resource Guide, Chapter 5 Sandi Cooper |3 3.

Discuss the NCTM Process Standards. Use PPT Slides #3-14, Process Standards, to highlight the NCTM recommendations.

4.

Have students brainstorm what the process standards might specifically look like in their classrooms. Use PPT Slides #15-16: Supporting Mathematics Learning with the Process Standards, to record their ideas. A few general ideas are included to get them started however encourage them to be more specific. For example, under communication, they might list “write in math journals twice a week”.

5.

Discuss different types of representations. Use PPT Slide #18: Five Ways to Represent Mathematical Ideas. Select a variety of concepts such as one-half, division, greater than, triangle, mode. Divide the class into five groups and assign each a different representation. Have them share their representation for each concept.

6.

Once you have completed chapters 1-6, the students will have received a good overview of recommended mathematics instruction in elementary classrooms. Chapter 7 will begin the second section of the text when individual mathematics topics will be addressed.

Give the students an opportunity to reflect on all they have learned so far and identify ideas they find to be most important. Use PPT Slide #19: Big Ideas for Teaching Mathematics and have them list 3-5 “big ideas” they plan to use in their own classrooms.

For each, have them list specific methods or materials they would use and also explain why this big idea is beneficial to children’s learning. Many of the reasons that support these methods may be found in chapters 1-6. An example is provided here that may help them get started. Once you have completed this exercise here, you might want to go back to it after you complete other chapters. For example, after completing Chapters 8-11, have students make a chart listing 3-5 Big Ideas for Teaching Number and Operations for Whole Numbers or after Chapter 17, make a chart with 3-5 Big Ideas for Teaching Data, Statistics and Probability. Having students complete these charts is also helpful when preparing for the Case History Exam Essay Questions.

EXAMPLE: Recommendation-Use a variety of manipulative materials Specific Methods/Materials-Keep a variety of counters and other manipulatives in tubs so small groups of students or individuals can use them when needed. Always begin development of new math concepts with concrete models students can handle.

Reasons why beneficial-We know children’s learning moves from concrete to abstract.

They need to be actively involved in learning.

7. In small groups, have students play the game, Rolling the Dice, on In the Classroom 5-1.

Give each group time to analyze the game using the questions on the card. Then have each student complete “Writing about the Game”. Finally, have them examine what the fourth-grade students wrote in Figure 5-2. Discuss the benefits of oral and written communication in mathematics learning. Identify the process standards that were used while completing this activity.

.S o n s

Instructor’s Resource Guide, Chapter 5 Sandi Cooper |4 8. Have students work in groups to complete the logical reasoning problems in Figure 5-5.

Share the children’s responses described in the chapter. Then discuss the connections to the process standards.

Student Supplemental Activities 1.

The use of the problem shown on PPT Slides #20-22: Pentominoes, provides students with a problem-solving situation. The setting is not a typical word problem from textbook mathematics but considers a more interesting, nonroutine problem. Prospective teachers need to experience problem solving firsthand and need to be encouraged to reflect on their approaches and solutions as Polya's problem-solving model suggests.

After the activity has been complete, discuss the process standards that were used while completing the activity.

Materials: PPT Slides #20-22, color tiles, grid paper, crayons or colored pencils • Show the examples and nonexamples of pentominoes using the PPT files and ask each student to write a definition of pentomino on the back of the provided grid paper. (Do not display the last question so that students remain focused on the definition step.)

• Have students share their definition with another student to allow comparison and clarification of definitions. Share several as whole class and decide on class definition of pentomino.

• Share the last question on the PPT. You will need to discuss what it means to be different. One way to gain agreement on this is to use color tiles on the overhead to present two pentominoes and ask if they are the same. Have the students supply reasons why or why not. Agree that if a figure has been slid, flipped, or turned, it is the same figure.

• Have students work in pairs to experiment using their color tiles to form the different pentominoes, recording their set of pentominoes on the grid paper. The use of color, rather than pencil or ink, makes it easier to distinguish the pentominoes on the grid paper.

• As the students work, circulate and observe how they are proceeding. Are they just randomly trying things or do some pairs seem to have developed a strategy?

• Come back together as a whole class and ask how many different pentominoes were found. Have students provide the 12 possible pentominoes making use of the overhead so all students have all 12 possibilities.

• Engage the group in a discussion of their experiences as learners in a problem-solving situation. Ask about the teacher's role during this time.

For further information about pentominoes and other activities involving their use, consider the article "Pentominoes Revisited" by Barry Onslow in the May 1990 Arithmetic Teacher. In addition, the book, Pentomino Activities, Lessons, and Puzzles

by Henri Picciotto provides over 200 Pentomino activities (listed in additional resources).

They also show that children are often intuitively able to solve problems with manipulatives or drawings for which they have not had formal instruction. Specific observations concerning each sample follow:

PPT #17 PPT #18 PPT #19 PPT #20 PPT #21 PPT #22 PPT #23

Meredith successfully solves the problem although she has not yet been introduced to the symbolic representations.

Allan successfully solves the problem. He knows the symbols for seven and four but does not place them in a number sentence.

Clint successfully solves the problem although he has not yet been introduced to the symbolic representations for division. He uses addition.

Bill successfully solves the problem. He uses a known fact of addition.

Darla knows how to add and adds the two numbers in the problem, then draws 18 circles to match her answer. When she is finished she says, "But I don't think he had 18 jars."

Ellen successfully solves the problem by placing an equal number of guppies in each jar. She has not yet been introduced to the symbolic representation for division and places the numbers in the format of a subtraction problem.

Allison successfully solves the problem using color tiles. Then she sketches her solution. She makes no attempt to represent it symbolically.

Encourage students to share observations about the work samples and what the children know.

List the numbers 1-19: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Notice if 19 goes in the center, the others can be paired (1,18) (2,17) etc. to give sums of 19. Add this to the center of 19 to give 38.

There are two other solutions. (a). Place 1 in center, then pair the others to sum to 22.

The total will be 23. (b). Place 10 in the center. Pair (1,19) (2,18), etc. Sum is 30.

Find three different integers a,b,c such that 1/a + 1/b + 1/c is an integer.

1/a + 1/b + 1/c = 1 a=6, b=2, c=3 1/6 = 1/2 + 1/3 =1/6 + 3/6 = 2/6 = 1 Choose 3 different whole numbers. Take their reciprocals and add them together. The sum should be a whole number. For example choose 2,5,8. Their reciprocals are 1/2,1/5,1/8. Their sum is 1/2 + 1/5 + 1/8. The sum is 33/40. These choices are incorrect because I wanted their sum to be a whole number.

Student Textbook Activities 1.

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2.

Hand out paper hearts or cubes and have students work in groups on the Valentine problem. Discuss the strategies used. Have students review the Chapter 6 Snapshot of a Lesson. The clip may be viewed at www.learner.org/resources/series32.html (video 42).

Discuss how acting out the problem helped children make sense of it and solve it.

3.

Use PPT Slide #3, Problem Types, to review the vocabulary introduced in the text.

Through discussion, students should determine that problem and nonroutine problem are synonyms and exercise and routine problem are synonyms. Use PPT Slides #4-6, Are these Problems or Exercises?, to give students practice in recognizing different problems and exercises.

4.

Use PPT Slide #7, Signposts for Teaching Mathematics through Problem Solving, to discuss considerations the teacher should keep in mind. Tie these recommendations back to the Snapshot of a Lesson, Valentine Exchange.

5.

Research findings concerning problem solving are discussed in the text. Use PPT Slides #8-9, Factors for Success in Problem Solving, to highlight and discuss the research findings.

6.

Problem solving is often thought of as solving word problems. By carefully planning for problem solving, teachers can provide students with the variety of experiences that are necessary to build a solid base for approaching any problem situation. PPT Slide #10, Choosing Appropriate Problems, presents a list of suggested problem types. Bring in

.S o n s

Instructor’s Resource Guide, Chapter 6 Sandi Cooper |9 texts and resource books and have students locate and share problems that match the criteria. You could assign various content strands and grade levels. This could also be an out of class assignment with time to share findings in class. Students could also bring in copies for the class so a problem solving file is assembled.

7.

Have students work on the traditional and open ended problems in Figure 6-3 and 6-5, or In the Classroom 6-1, Which Rectangle is Biggest? Next, bring in some traditional texts.

Have students locate a traditional problem for each NCTM content strand. Then have them work together to turn them into open ended problems. These could be duplicated for the class file.

8.

Discuss the principles for helping students pose problems, found in the text. Then bring in some children’s books and have the class work in small groups to create some problems.

9.

Recommendations concerning the use of technology with problem solving are presented in the text. It would be useful to present calculator and computer activities that demonstrate the recommendations.

10.

The text identifies Polya’s 4 stage problem solving model and 7 specific problem-solving strategies and provides examples of problems that can be solved using those strategies.

PPT Slides #11-12, Problem Solving Strategies, provides a list of the strategies. Discuss each strategy and have the class provide further examples to fit each category.

11.

The text presents a variety of problems to illustrate 7 specific strategies. Begin with a demonstration of the strategy, "act it out". Use PPT Slide #13 to present the horse problem that was in the text. After students have worked the problem independently, record suggested solutions on the board. There will probably be 3-4 different solutions provided. Next, have two volunteers come to the front of the class and act out the problem according to the class' direction. If each actor starts with 10 "ten dollar bills", they can complete the necessary transactions and count the remaining bills. The buyer ends up with $120 and the seller ends up with $80. Discuss the results and the value of acting out the problem.

Assign students to work on several problems from the text, using the recommended strategy. Encourage them to reflect on how they approached the problem and to share alternate approaches to finding an appropriate solution.

Chapter 7 — Developing Counting and Number Sense in Early Grades Chapter Overview This chapter addresses the important role that number sense plays in the development of computational concepts and skills. This understanding of numbers zero to ten is basic to a students' future with larger numbers and the concept of place value. Three pre-number concepts, consisting of classification, patterns, comparisons, and two early number development concepts consisting of conservation, and group recognition are introduced. Counting and its various stages and strategies are outlined together with 4 counting principles. The relationship between a set of objects, the number name, and the written symbol is noted. Cardinal, ordinal, and nominal numbers are defined. Recommendations for teaching the writing of numerals are presented.

Student Objectives After reading the chapter, the students will be able to: 1.

Summarize characteristics of children with good number sense and provide examples of observable number sense behaviors.

2.

Summarize the pre-number concepts of classification, patterns, comparisons, and early number development concepts of conservation, and group recognition as well as provide examples of activities that promote their development.

3.

Identify counting principles, stages, and strategies as well as provide examples of activities that promote their development.

4.

Identify number benchmarks and visual patterns for connecting groups of objects with the oral name and symbolic representation.

5.

Differentiate among cardinal, ordinal, and nominal numbers.

6.

Summarize recommendations and provide examples of activities for teaching the writing of numerals.

Key Vocabulary The terms listed here are important to the understanding of the important role of numbers and counting in developing future mathematical concepts. Students need to gain familiarity with these terms and use them appropriately. number sense classification patterns comparisons conservation group recognition .S o n s

Instructor’s Resource Guide, Chapter 7 Sandi Cooper |2 Supplemental Lecture Topics 1.

Display and discuss PPT Slides # 32-38, Student Work Samples. They are writing samples taken from kindergarten children during the third month of school. The children were asked to begin with one and write their numbers to ten. The samples are intended to show the wide range of writing skills encountered within one class of students. Specific observations, focusing on what the child can do, follow: PPT # 32 Chad makes figures to symbolize the numerals.

PPT # 33 Cody indicated that the first row was 1-5 and the second row was 6-10.

He writes horizontally from left to right and makes a discrete symbol for each numeral.

PPT # 34 Steven repeated the use of several symbols in a variety of combinations.

The directionality of the numeral two varies.

PPT # 35 Elizabeth writes the numerals 1-5 horizontally, from left to right. All numerals are pointing to the right.

PPT # 36 Andrea writes the numerals 1-12 horizontally, from left to right. All numerals are pointing to the right and the numerals 6 and 9 are omitted.

PPT # 37 Jason correctly writes the numerals 1-10 and also draws the number of blocks each numeral represents.

Display PPT #38 to show that it is often common for older children to reverse numerals and not a cause for concern. Joshua is a second grader asked to write the numbers 1-25.

.S o n s

Instructor’s Resource Guide, Chapter 7 Sandi Cooper |3 4.

Have students review the Chapter 7 Snapshot of a Lesson. It may be viewed at www.learner.org, video #3. Discuss the counting and early number concepts displayed.

5.

Display PPT Slide #7, Pre-Number Concepts. Allow the class to brainstorm activities and materials that may be used to develop the five concepts (classification, patterns, comparisons, conservation, group recognition) discussed in the chapter.

6.

Classification is an important concept to be developed for all elementary students.

Duplicate and cut apart the attribute pieces (Appendix B). Or use commercial attribute blocks or other sortable objects such as colored pasta, cereal, beans, buttons, ceramic tiles, etc. Have students complete In the Classroom 7-1 and 7-2. Finally, refer the students to Figure 7-5. Have them make two intersecting circles with yarn. A leader selects a mystery attribute for each circle. Others in the group take turns placing pieces.

The leader confirms whether a piece is placed correctly. Play continues until someone correctly guesses the mystery attributes. You may wish to begin by modeling the activities and have students work together in small groups. It is appropriate to discuss the different levels of involvement and understanding experienced in a whole class demonstration versus a small group, hands on setting.

7.

Discuss the four types of pattern activities discussed in the chapter (copying a pattern, finding the next one, extending a pattern, making a pattern), then provide an opportunity for students to experience the activities. Materials which could be used include pattern blocks, color tiles, connecting cubes, and other sortable objects such as colored pasta, cereal, beans, buttons, ceramic tiles...

8.

PPT Slides #12-14, Conservation of Number, provides hypothetical conservation interview excerpts with two children. Have students use the information provided in the text to determine the children's conservation of number. Student A is not able to conserve number and Student B is able to conserve number.

9.

PPT Slides #18-20, Counting, summarizes the counting principles, stages, and strategies.

Use counters on the projector to provide examples for each.

10.

PPT Slides #26-29, Counting Principle Examples, provides examples of children's counting. Have students use the information provided in the text to analyze the children's use of the counting principles. Encourage students to focus on what the children know rather than what they do not know.

• Student A is displaying the stable order rule and the cardinality rule.

• Student B is displaying the one to one rule, the stable order rule, and the cardinality rule.

• Student C is displaying the order irrelevance rule and the cardinality rule.

• Student D is displaying the cardinality rule.

11.

Have students work together on In the Classroom 7-3, Numbers on a Calendar. Then have them make up additional problems and share them with the class.

.S o n s

Instructor’s Resource Guide, Chapter 7 Sandi Cooper |4 12.

Have students use calculators to complete In the Classroom 7-4, Counting On…and On…and On, and 7-5, Counting On…and Back, in the text. Discuss other calculator counting activities that could be done with children.

13.

Once they have learned to count on the calculator, have students complete In the Classroom 7-6, Hunting for Numbers, and 7-7, Skip Counting. Then have them use the calculator and crayons to shade some of the 100's charts in Appendix B and look for patterns that emerge.

14.

Have students examine Figure 7-18, then use the five- and ten-frames in Appendix B. Students can place connecting cubes, color tiles, or beans in the frames. Challenge the students to find more variations for the numbers shown and to continue the examples for the numbers 11 to 20.

Student Supplemental Activities 1.

PPT Slides #30-31, Construct a Pattern, involves students in the creation of patterns following specific conditions. The slide outlines the directions for the activity.

Materials: PPT Slides #30-31, color tiles (at least 20 per student), color spinner (may be constructed from the spinner patterns in Appendix B), and timer.

• Present the directions for the pattern activity. Provide an example to clarify any questions about how the activity will proceed.

• Spin the spinner twice to determine the two colors to be used, remind the students that the pattern they construct must repeat at least twice, set timer and let students create!

• At the end of the allotted time, have several students present their patterns. This could be done using an overhead set of color tiles or using construction paper squares on floor or chalkboard. Determine if anyone had a unique pattern.

• Vary the number of colors to be used, the number of times the pattern must repeat, or use different types of manipulatives. The use of attribute blocks would allow more diversity in developing patterns by using color, shape, size in setting criteria for building patterns.

• Discuss the role that patterning plays in the mathematical development of learners. What are other activity ideas that could be used?

2.

Bring the class a collection of available counting books. Distribute them randomly to each small group for discussion of similarities and differences. For example, not all counting books choose to address the concept of zero. As a follow-up, have each group construct their own counting book, picture or slide collection using the best of what they have seen. For example, read the book, Ten Black Dots, then have groups create their own book pages using adhesive dots. Another option would be to assign each group a different number and have them represent that number in as many different ways as possible.

.S o n s

Instructor’s Resource Guide, Chapter 7 Sandi Cooper |5 3.

Give each small group a set of objects and ask them to find at least 3 different ways to classify the items. Suggestions for objects: the right shoe of all students in the class, a box of assorted books, items from your middle desk drawer, or a handful of buttons or seashells. Classification is a necessary skill not only for mathematics but for other subject areas, such as science.

4.

Share some other activities that encourage the development of pre-number concepts from the classic book, Mathematics Their Way, by Mary Baratta-Lorton.

5.

Have students view the tapes, Number Sense Now in the additional resource list or review the activity books, Number SENSE, in the additional resources list. Have the students generate a list of activities which would help develop number sense.

6.

Show a clip from the video, Six Models. First graders are making attribute block trains.

7.

Have students complete activities from Navigating through Numbers and Operations in Prekindergarten-Grade 2.

8.

Instructor’s Resource Guide, Chapter 8 Sandi Cooper |1

Chapter 8 — Extending Number Sense: Place Value What This Chapter Is About This chapter stresses the importance of understanding our number system in order to develop mathematical literacy. Characteristics of our number system are reviewed. The use of concrete models, ungrouped and pre-grouped, both proportional and non-proportional, is presented as a necessary bridge to the more abstract concepts of place value. The connections between place value and rounding are discussed. Recommendations for teaching the reading and writing of numbers are included. Examples of activities that help to develop place value concepts are provided throughout the chapter.

Student Objectives After reading the chapter, the students will be able to: 1.

Summarize characteristics of our numeration system and place value.

2.

Summarize place value grouping, trading, patterns, and modeling including the use of both ungrouped and pre-grouped materials, and proportional and non-proportional models as well as provide examples of activities which promote their development.

3.

Summarize place value instruction including moving from concrete to symbolic place value representations.

4.

Describe reading and writing numbers as well as provide examples of activities and models that promote their development.

5.

Describe rounding as well as provide examples of activities and models that promote its development.

Key Vocabulary Number sense is firmly based on the concepts of place value. Students should be aware of the characteristics of our number system and discuss place value concepts using the correct terminology. place value grouping or trading proportional models non-proportional models symbolic rounding

Elsa can accurately write numbers through ten thousands.

Have students brainstorm other questions or activities that would further clarify the child's understanding for the teacher.

Student Textbook Activities 1.

.S o n s

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

Instructor’s Resource Guide, Chapter 8 Sandi Cooper |3 2.

Have students review the Chapter 8 Snapshot of a Lesson. It may be viewed at www.learner.org, video #4. Discuss the types of place value models used.

3.

The numeration system we use has four very important characteristics that are listed in the text. Review each characteristic and have students provide examples to illustrate each.

4.

Children need a thorough understanding of place value in order for computation instruction to be meaningful for them. In Chapter 8, the two key ideas on which place value rests are presented. They include: 1.) Explicit grouping or trading rules are defined and consistently followed. 2.) The position of a digit determines the number being represented. Discuss each key idea and demonstrate them with the use of a place value model such as base-ten blocks.

5.

Discuss and demonstrate the difference between ungrouped and pre-grouped place value materials. For example use connecting cubes to represent numbers both ungrouped and pre-grouped.

6.

Proportional and non-proportional place value models are illustrated in Figure 8-4. PPT Slides #6-8, Proportional and Non-proportional Place Value Models, provides definitions and examples for each. Before showing the Master to students, use a variety of materials to demonstrate how each type of model may be used to model whole numbers. Provide students with some color tiles or other colored counters and ask them to see if they can illustrate place value in both a proportional and non-proportional manner. Confirm their models with PPT Slides #6-8.

7.

Have the students use a place value mat and base-ten blocks to play Race-to-Flat, In the Classroom 11-4 from Chapter 11. Discuss with students how this is an example of a proportional place value model. Next, using a relabeled place value mat, play the game again using color tiles. The new game may be called Race-to-a-Green and the headings on the mat may be changed to Green, Red, Yellow. Once students have collected 10 yellows, they may trade for one red tile. Once they have 10 reds they may trade for a green tile. Discuss how this is an example of a non-proportional model.

8.

It is important that children are assisted in making the connection between concrete place value models and abstract symbols. Figures 8-7 and 8-8 illustrate how the connection may be made. PPT Slide #9, Moving from Concrete to Symbolic Models, provides an illustration for Figure 8-7 and may be used to highlight the connection.

9.

Give students experiences using a variety of manipulative materials to model numbers.

Consider using a variety of both ungrouped and pre-grouped, proportional and nonproportional materials for students to explore using trading mats. Use Figure 8-11 to provide an additional example of regrouping. This opportunity for hands-on experience with these manipulative materials allows students to make decisions about appropriateness for use and provides a background for further teaching experiences. It is

.S o n s

Instructor’s Resource Guide, Chapter 8 Sandi Cooper |4 also appropriate to introduce homemade alternatives to commercial materials such as bean sticks or paper models (Appendix B).

10.

Many place value ideas may be developed through the use of hundreds charts. Use the charts (found in Appendix B) to complete In the Classroom 8-1 and In the Classroom 8-4, found in the text.

11.

An important place value idea, which prepares students to regroup during computation, involves representing numbers in more than one way. In the Classroom 8-2 illustrates how students can be encouraged to represent numbers with various combinations of ones, tens, and hundreds. Ask students to find several solutions for the last two targets. Share the results and discuss other variations that might be used with students.

12.

The calculator is another valuable tool that may be used to assist students in identifying place value patterns. Figure 8-9 demonstrates how the calculator may be used to count be ones, tens, etc. and Figure 8-10 shows how to count back and illustrate integers. On most four-function calculators, you can enter a starting number, plus sign, an addend, and then repeatedly press the equal sign to continue adding the addend. For example, 0 + 1 = = = = will progressively display the numbers from 1 to 5. Have students also examine In the Classroom 8-3 to see another idea for using calculators to investigate place value concepts. The students may also use the calculator to play the game "Wipe-Out", described in the text.

13.

Some concrete models for rounding numbers are provided in the text. Allow students to use those materials to model the rounding of whole numbers. Then discuss the pros and cons of each model. Also encourage students to develop a model for rounding to the nearest ten on a hundreds chart (Appendix B). Could the model be extended to allow students to represent rounding to the nearest hundred?

14.

The Math Links in this chapter provide students with additional electronic manipulatives and video examples for place value. In class, or as an outside assignment, have students explore these web sites.

15.

Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book.

16.

The Book Nook for Children, found in the text, lists several children's books which may be used when studying place value. Bring several of these books to class and have students brainstorm ways in which they could be used in a math lesson.

Student Supplemental Activities 1.

2.

Have students investigate the development of our numeration system. A look at other early number systems can serve to clarify the uniqueness of our system. This investigation connects history to mathematics and allows students to appreciate the role that mathematics plays in past and present civilizations.

3.

Have students examine elementary textbooks to see how the concepts of place value and estimation of quantity are developed.

4.

Show the tape, Mathematics with Manipulatives: Base Ten Blocks, by Marilyn Burns (Available from Cuisenaire) or videl #3 from the Annenberg Teaching Math: A Video Library, K-4. Discuss the place value concepts children are developing.

5.

Provide a variety of calculator activities for students to try. The text provides several examples of activities and references of other sources with interesting calculator ideas.

Do several as a whole class activity. Have students work on certain activities individually, and have them work as pairs to play any of the many calculator games.

After they have spent some time working with the calculator, engage the students in a discussion about their experiences. Did they have to think while using the calculator?

What other skills were they using during their work time?

6.

Bring some teacher resource books to class that provide place value activities. Allow students to review the books and preview some of the activities. For example, The Place Value Connection, Navigating through Number and Operations, Lessons for Introducing or Extending Place Value (see additional resources) may be used.

Chapter 10 – Computational Methods: Calculators, Mental Computation, and Estimation What This Chapter Is About In this chapter, the computational alternatives of estimation, mental computation, and calculator computation are discussed. The importance of balanced instruction and encouraging appropriate method choices are stressed. Suggestions for when to use the calculator as a computational tool and an instructional tool are provided. A rationale for helping children to develop mental computation is provided as well as guidelines for providing mental computation instruction.

Guidelines for providing estimation instruction as well as the computational estimation strategies of front-end, compensation, flexible rounding, compatible numbers, and clustering are discussed.

Student Objectives After reading the chapter, the students will be able to: 1.

Summarize recommendations concerning alternative computational methods and computational choice.

2.

Summarize recommendations concerning the use of a calculator as a computational tool and an instructional tool as well as provide examples of activities which promote its use.

3.

Summarize recommendations for teaching mental computation as well as provide examples of activities and models which promote its development.

4.

Summarize recommendations for teaching computational estimation strategies as well as provide examples of activities which promote their development.

Key Vocabulary As in the previous chapter, computation is the focus of most elementary mathematics programs.

The terms below are key to extending computation beyond basic understanding and facts. computational tool instructional tool mental computation computational estimation front-end estimation

Use PPT Slides #3-4, Number and Operations Standard: Compute fluently and make reasonable estimates, and PPT Slides #5-6, Number and Operations Standard: Understand numbers, ways of representing numbers, relationships among numbers, and number systems, to highlight the key recommendations related to computational alternatives in grades K-5 from NCTM's Principles and Standards. Discuss these recommendations.

2.

Discuss the role of calculators in the teaching of mathematics. Calculators in Mathematics Education, the 1992 NCTM Yearbook, has many useful articles. Research findings may also be introduced. An excellent overview, "Research on Calculators in Mathematics Education" by Hembree and Dessart is provided in the same yearbook.

3.

In the NCTM book, Mathematics for the Young Child, (see additional resources) Chapter 8, Whole Number Computation, provides additional material which may be used.

Written computation as well as computational estimation and mental computation are discussed. Examples of mental computation strategies such as bridge tens and doubles are provided as well as the estimation strategies of reference points, nice numbers, frontend estimation, and rounding.

4.

The 1986 NCTM Yearbook, Estimation and Mental Computation, provides additional information about teaching computational estimation and mental computation. Use this book to bring up additional issues concerning the teaching of these topics.

5.

A broad view of computation is provided in the book, Computational Alternatives for the Twenty-first Century: Cross-Cultural Perspectives from Japan and the United States(1994), edited by R. Reys and N. Nohda. (Available from NCTM.) The topics of mental computation, computational estimation, and the use of calculators are all discussed and may be used to stimulate discussion on those topics.

6.

Most of the undergraduate students have not had formal instruction in using a variety of strategies for mental computation and computational estimation (other than rounding).

Bring in books such as Mental Math in the Primary Grades, Computational Estimation, and Number SENSE which provide lessons teachers may use to teach specific mental computation and estimation strategies. Introduce several of the strategies and discuss introducing them to elementary children.

Student Textbook Activities 1.

.S o n s

As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

Instructor’s Resource Guide, Chapter 10 Sandi Cooper |3 2.

Have students review the Chapter 10 Snapshot of a Lesson. It may be viewed at www.learner.org. Discussion should connect the Snapshot to NCTM Standards recommendations for computation.

3.

Discuss with students, Figure 10-2. The NCTM Principles and Standards recommend a balanced approach to computation. Compare the recommendation with the current practice found in most elementary classrooms. Have students examine Figure 10-3.

Today, many teachers continue to emphasize paper-and-pencil computation at the expense of the other types of computation. If the recommendation for computational decision making were supported by those teachers, how would their instruction change?

4.

Use PPT Slides #8-10 Myths and Facts of Calculators, to summarize the use of the calculator as a computational tool and as an instructional tool. Provide examples of activities that illustrate each recommendation. Visit the Texas Instrument web site for ideas. The Keystrokes books (in chapter selected references) are also good resources for instructional tool activities.

5.

Mental computation has often been ignored in the elementary curriculum. PPT Slides #21-23, Guidelines for Teaching Mental Computation, highlights the recommendations made in the text. Discuss these points with students and allow them to brainstorm ways mental computation could be regularly included in an elementary math class.

6.

Most students today learned only one computational estimation strategy in elementary school-rounding. PPT Slides #31-32, Guidelines for Teaching Estimation, provides suggestions for estimation instruction. PPT Slide #33, Computational Estimation Strategies, highlights the five strategies discussed in the text. Discuss each strategy and have students provide problems which might be solved using that strategy.

7.

In the Classroom 10-1 may be used to demonstrate appropriate use of a calculator.

Divide the class into two groups and conduct the activity. Discuss potential uses with children.

8.

In the Classroom 10-2 and 10-3 provide examples of a "choice" activity. Have students brainstorm which types of problems might be appropriate for each of the three computational methods. They can also discuss how the appropriateness of each tool depends on each individual's skill and confidence.

9.

In the Classroom 10-4 encourages students to use front-end estimation skills. Encourage students to brainstorm how the card may be adapted for children of different ages.

10.

The Book Nook for Children, found in the text, lists several children's books which may be used when studying computational methods. Bring several of these books to class and have students brainstorm ways in which they could be used in a math lesson. Encourage students to locate additional children's literature titles that may be used in computation instruction. For example, Counting on Frank by Rod Clement encourages students to estimate quantities. This title is available from Cuisenaire Publications.

Instructor’s Resource Guide, Chapter 10 Sandi Cooper |4 Student Supplemental Activities 1.

PPT Slides # 11-14, Calculator Test Items, presents 6 test items for class discussion. For each item, have students decide if students should use a calculator, should not use a calculator, or it does not matter. Using their responses and ideas, discuss how assessment changes in the face of available technology. The article, "Using Calculators on Achievement Tests" (additional resources) provides additional information on the subject.

2.

PPT Slides # 15-16 presents the Three-Step Challenge Problem which uses calculators to explore a challenge and arrive at multiple solutions. Estimation skills are also being used in trying to develop a problem-solving strategy for determining a solution. The problem involves students with discovering how to move from a starting number to a target number using only certain operations and a limited number of steps. The activity comes from "IDEAS from the Arithmetic Teacher: Grades 4-6 Intermediate School", a set of activities compiled by Fennell and Williams (NCTM, 1986, p. 11-12). Materials needed for this include PPT Slides #15-16 and calculators.

• Distribute calculators or make sure that students have access to their own calculators.

• Present the challenge outlined on the overhead transparency. To make sure there are no questions, you may want to present one solution.

• Allow students to work and as you observe students finishing the first challenge stated, encourage them to develop their own challenge. Have the students who are prepared then exchange their constructed challenges.

• Discuss the experience and have several students share their challenge questions with the class as other variations of the original challenge.

This activity allows students to use technology in connection with developing a sense of operations and how they are interrelated.

3.

Encourage students to use resource books and textbooks to locate activities where the calculator may be used as a computational tool and an instructional tool. For example, find a problem solving activity, a pattern activity, a concept development activity, etc.

View the PRIME video (see additional resources) and discuss how the calculator is being used in elementary classrooms.

4.

Students need the opportunity to see for themselves how a problem may be solved in several different ways and how class discussions allow students to verbalize their strategies and learn about other strategies from their classmates. PPT Slides # 24-26, Mental Computation, provides three problems for which an exact answer may be calculated mentally and two which may be estimated.

Review the difference between mental computation and computational estimation (mental computation is exact and estimation is approximate). Then, one at a time, briefly

.S o n s

Instructor’s Resource Guide, Chapter 10 Sandi Cooper |5 display the problems. Have volunteers explain how they solved the problems. See how many different solution processes were used.

Various mental computation strategies may be discussed. Figure 10-6 provides several examples for addition. The estimation strategies discussed in the text (PPT Slide #33, Computational Estimation Strategies) may also be reviewed at this time. Review how the NCTM Principles and Standards are also encouraging multiple solution processes for written computation as well. Discuss the implications for classroom teachers.

5.

PPT Slides #27-29, A Student’s View of Mental Computation, presents how a "typical" middle grade student feels about mental computation. Share the student's view and have students discuss the kind of math classroom this student might be in. Also have them brainstorm additional activities and experiences this student might benefit from.

6.

Have students examine several elementary textbooks to see how mental computation, calculator computation and estimation are introduced and presented. How do the texts reflect the NCTM recommendations? Are concrete materials used? Are students encouraged to invent solution processes? How large are the numbers in the problems that students are asked to solve?

7.

Have students preview computer software which has students working with calculator computation, mental computation, or estimation. Discuss the strengths and weaknesses of each.

8.

The Math Links in this chapter provide students with additional electronic manipulatives for computational algorithms. In class, or as an outside assignment, have students explore these web sites.

9.

Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book.

10.

Using the References listed at the end of the chapter, have students locate additional information on topics that interest them concerning computational alternatives. Divide students into groups of 4. Have each person in the group read and report on one article.

Chapter 12 — Fractions and Decimals: Concepts and Operations What This Chapter Is About The focus of this chapter is on how to meaningfully approach fractions and decimals.

Meaningful teaching makes use of models and language to develop understanding of fractions and decimals before moving to the symbols used for representation. The point is made that just as with whole-number operations, operations with these numbers must be given meaning and not simply presented as rules to be followed. Partitioning, equivalence, benchmarks, and three meanings of fractions are introduced. Four models for the part-whole meaning of fractions and models for fraction algorithms are provided. The relationship of decimals to fractions and place value are discussed as well as decimal algorithms.

Student Objectives After reading the chapter, the students will be able to: 1. Explain and illustrate partitioning, equivalence, and three meanings of fractions.

2. Provide examples for the four models of the part-whole meaning of fractions.

3. Summarize steps for helping children make sense of fractions.

The samples are intended to show the wide range of understandings among children. Specific observations concerning each sample follow: PPT #32

Charles is able to represent the fractional symbols with pictures and successfully solves the comparison problems.

PPT #33 Amanda has not yet studied fractions in the fourth grade. She uses her knowledge of whole numbers to solve the problems. No fraction pictures are used. In the comparison problems, she identifies the fraction with the largest numeral in the denominator as largest. In the addition problems, she adds the numerators and adds the denominators.

PPT #34 Amy successfully adds two fractions with like denominators. When solving addition with unlike denominators, she is unsure what to do. She attempts to draw a picture but is unsuccessful so she adds the numerators like the previous problem and uses four as a denominator.

Ask students to brainstorm other questions or activities which would further clarify the child's understanding for the teacher. What activities could be provided for Amanda and Amy? .S o n s

Instructor’s Resource Guide, Chapter 12 Sandi Cooper |3 Student Textbook Activities 1. As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about.

Student Supplemental Activities 1. Have students use grid paper, color tiles, markers, or other materials to form designs in an 8 by 8, 6 by 12, 10 by 10, or other dimensioned area. Consider questions such as: What fraction of your design is red? other color? Which is a greater fraction of your design, red or yellow? Have students compare fractions by using their sets of fraction bars to represent the fractions found in the design formed. If students work within a 10 by 10 framework, relationships among fractions, decimals, and percents can be illustrated.

2. Have students divide into small groups and give each group a different fraction. Ask them to represent that fraction in as many different ways, in as many different representations as possible. Have manipulatives, grid paper, paper, markers, and other supplies available for their use. To share their fractional presentations, have each group construct a bulletin board or other visual display of the many models found. Allow groups to rotate through each display to discover the creative discoveries of others groups in the class and extend the ideas available for use in teaching children.

3. Consider involving the class in an activity which uses calculators which have a fraction key. These calculators allow students to move from fractional representations to decimal representations and back again. Exploration using this type of technology will help students further clarify the role that technology can play in the teaching and learning of mathematics at the elementary school level.

Student Supplemental Activities

.S o n s

Instructor’s Resource Guide, Chapter 13 Sandi Cooper |4 1. Students should also be encouraged to use what they know about the properties of multiplication when solving percent problems. David Glatzer's article, "Teaching Percentage: Ideas and Suggestions", (in Chapter 12 selected references) provides several excellent percent activities. PPT Slides #21-22, Percent Shortcuts, offers some of Glatzer's suggestions for easily solving percent problems mentally which are interesting for students. For example: A% of B = B% of A (commutative property) While 28% of 50 would be difficult to solve mentally, 50% of 28 is quite manageable and yields the same result as the more difficult problem.

(K x A)% of B = K(A% of B) (associative property) Students may not be able to find 20% of 35 mentally. However, if they know how to find the benchmark 10%, the problem becomes easier. 20% of 35 is the same as (2 x 10)% of 35 which is also equivalent to 2(10% of 35). I can find 10% of 35 which is 3.5, then I double it to get 7.

(A+C)% of B=(A% of B) + (C% of B) (distributive property) The classic dilemma of calculating a 15% tip after a $60 meal in a restaurant can be reduced to a simple mental calculation. 15% of $60 is the same as (10+5)% of $60 which can also be expressed as (10% of $60) + (5% of $60). I know 10% of $60 is $6.

I also know that 5% is half of 10% and that would be 3. I add $6+$3 to get $9.

2. Tangrams are useful manipulative materials for geometry topics but this problem connects them to ideas of percent. Materials: PPT Slide #23, Tangrams and Percent, sets of tangram pieces, rulers, grid paper.

• Distribute materials or make sure each student has brought the necessary materials for the activity.

• Present the directions using the overhead transparency and answer any questions about the directions. To calculate the areas of the various tangram pieces, student may want to measure lengths of sides and altitudes, or they could use grid paper of an appropriate size by tracing the pieces onto the grid and calculating the needed area.

• Allow students time to complete the activity before sharing the results.

• As results are shared, ask if everyone got the same answers. Some students will use different units of measure in calculating the areas of the tangram figures, does this affect their calculations of percentage of area for each tangram piece?

While you have the tangram pieces available, discuss other ways in which tangrams can be used. What kinds of questions can be asked? What kind of figures can be constructed using the pieces? This and other activities by Edna F. Bazik are included in "Projects to Enrich School Mathematics: Level 2" (NCTM, 1988, p.42-50).

3. Divide the class into small groups and send them outside of the classroom to find ratios.

For example: ratio of open doors to closed doors in the hallway, ratio of sneakers to dress shoes, ratio of cars to bikes, or ratio of eye color. Have supplies available for the students to construct visual representations of the data gathered. Share the creative ratios found by the class and the chosen representations. .S o n s

Instructor’s Resource Guide, Chapter 13 Sandi Cooper |5 4. Have students use 10 by 10 grid paper to work with concepts related to percent. Have them construct a design that uses 73% or some other chosen percentage of the square.

Have the group brainstorm other activities that could use the grid representation for percent.

5. Collect maps of different states, countries, and cities and rulers for use in this activity.

Calculating the distance traveled on the map involves the use of ratios. Have each pair of students share a map and pose different questions. For example: From your chosen starting point, travel 150 miles North. Where are you? Another activity would allow you to set expense limits for a trip to be planned by the student pairs. In solving the problem students would have to consider distance, cost of gasoline, food, lodging, and other travel expenses. Additional questions might include, What percent of your budget was spent on food? on travel?

6. Teaching Arithmetic: Lessons for Decimals and Percents, NCTM's Addenda books for the Middle Grades, Understanding Rational Numbers and Proportions, and Developing Number Sense in the Middle Grades, provide activities for developing the concepts of ratio, proportion, and percent. Have students work together to review these books and present an activity to the class.

7. Marilyn Burns offers several activities which develop the concept of ratio and percent using Cuisenaire Rods and other materials. For examples, see her book, A Collection of Math Lessons From Grades 6-8, and the videos, Mathematics: for Middle School, Part 1 and Part 3. All are available from Cuisenaire Company. Allow students to view the video segments, then actively experience the activities themselves.

8. Bring in an example of materials which can be used to develop a replacement unit for ratio/proportion/percent. Have students discuss how they would organize the unit. For example, Similarity and Equivalent Fractions, from the Middle Grades Math Project, or Ratio, Proportion, and Scaling from the Mathematics Resource Project.

9. The Math Links in this chapter provide students with additional electronic manipulatives and video clips. In class, or as an outside assignment, have students explore these web sites. The National Library of Virtual Manipulatives has an applet for percentages (in 3-5 and 6-8).

10. Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book.

Instructor’s Resource Guide, Chapter 14 Sandi Cooper|3 8. The Book Nook for Children, found in the text, lists some children's books which may be used in the study of patterns and algebra. Encourage students to read and review these and others that may be appropriate.

Student Supplemental Activities 1. This problem allows student to use manipulatives to model a pattern. Then they are encouraged to make a generalization and then use symbols to represent the pattern.

Materials: PPT Slides #15-16, Growing Patterns, color tiles, calculators • Display the PPT Slide and ask students to investigate as directed in the problem. Have color tiles available for student use.

• Have students get in small groups and share ideas. Then have a whole class discussion on modeling, generalizing and justifying.

Use T Charts to show some of the relationships that can be found.

2. This problem involves investigating number patterns with ninths and elevenths.

Materials: PPT Slides #13-14, Patterns in Fractions, calculators, computer with spreadsheet software (optional).

• Display PPT Slides #13-14 and ask students to investigate as directed in the problem. Have calculators available for student use.

• Do not specify how they are to work the problem or how they should proceed.

Observe the class as they begin. Do they work alone, do they choose to use the available calculators?

• Bring the class back together and discuss what they have discovered. Ask what the focus of the problem was - to divide two numbers or to look for patterns?

Does technology make sense for use in this situation? Why or why not? Ask them to think about how they approached the problem, did they assume they were to work alone? Why? Did they reach for the calculator or begin to work with pencil-and-paper? What would they expect their students to do? .S o n s

Instructor’s Resource Guide, Chapter 14 Sandi Cooper|4 • You may want to set up the problem using a computer spreadsheet and demonstrate how it becomes a simple matter to look at any denominator, see many cases on the screen, and be able to hypothesize about the existence or nonexistence of a pattern. An example of the setup, using EXCEL, is provided below. With a little experimentation, the spreadsheet programs available are easily accessed and can be used in many situations. Your students may have had experience with spreadsheets and this may be an opportunity for them to share that knowledge with the rest of the class and with you.

3. The Palindrome Problem involves the use of place value ideas within an interesting problem situation. Materials: PPT Slides #23-25, Palidromes, copies of hundred boards, colored markers or crayons, calculators (optional).

• Begin by considering word palindrome examples given on PPT Slide #23. See if the students can suggest other words which are palindromes. Challenge them to form a sentence which is a palindrome - reading the same forward and backward.

One example, Able was I ere I saw Elba.

• Transfer from word palindromes to number palindromes with the next question.

Have students provide a definition of palindrome.

• Turn to the hundred board and have students circle in one color all the palindromes found on the board. This step can be done individually or as a class group. Is there a pattern?

• Consider a number that is not a palindrome, for example 57. Can we transform 57 in some way to form a number that is a palindrome? Add 75 to 57 and the answer is 132 which is still not a palindrome. Add 231 to 132 and the result is 363 - a palindrome! We then call 57 a two-step palindrome. Mark 57 on the hundred board with a color to represent two-step palindromes.

• Try this process on various other numbers to see if there are patterns which seem to develop.

• This chapter addresses the topic of place value. Ask the students how this problem relates to this topic, how the idea of palindromes could be used in classrooms.

.S o n s

Instructor’s Resource Guide, Chapter 14 Sandi Cooper|5 4. Start by having students give definitions of even and odd numbers. Have them think about the process of understanding this concept. What concrete and pictorial experiences could be used to develop understanding of even and odd numbers? Using inch grid paper and color tiles or connecting cubes, investigate the shape of even versus odd as discussed in the text. Have students discuss how this setting can be used or extended to connect to other number ideas, such as factors of numbers.

5. Have groups or pairs of students construct patterns using color tiles, centimeter dot paper, other size grids or other materials (See Appendix B). Have them prepare an example of a repeating pattern and an example of a growing pattern. This provides you with an opportunity for assessment of their understanding of the two types of patterns discussed in the text and an opportunity to discuss assessment.

6. NCTM's Addenda books, Patterns, and Patterns and Functions both provide activities for developing pattern and number theory concepts. Historical Topics for the Mathematics Classroom provides number theory activities. Lessons for Algebraic Thinking from Math Solutions provides additional lessons. Have students work together to review these books and present an activity to the class. Students could also view video lessons on patterns and relationships from Teaching Math: A Video Library such as People Patterns, All Sorts of Buttons, Products and Sums, and Valentine Exchange (grades K-4) and Building Rafts with Rods (grades 5-8).

7. The resource book, Mathematics Their Way, (see additional resources) provides many examples for how young children may be introduced to patterns. Have students demonstrate some of the activities it contains.

8. Challenge groups of students to participate in a “patterns in the real world” scavenger hunt. Develop a bulletin board to display their findings.

9. Encourage students to locate other pieces of children's literature which contribute to the study of patterns and algebraic thinking. For example, One Hundred Hungry Ants by Pinczes, introduces factors of 100, One Grain of Rice by Demi introduces the classic problem of what happens if an item is doubled each day, and Two Ways to Count to Ten

by Ruby Dee investigates factors and multiples. All are available from Cuisenaire Company. Following is an example of how literature can be incorporated into a lesson.

10.

.S o n s

Literature presents an interesting way in which to introduce new mathematical topics or explore mathematical ideas in a new representation or situation. An example of the use of literature in connection with technology can be seen in the use of the book, The King's Chessboard by David Birch . In this book, a proud king grants a wise man one wish. His wish is that he receive a grain of rice on the first day, and for each following day the amount of rice is double the previous day. This is to continue for each day of the chessboard, sixty-four days. Materials: The King's Chessboard by David Birch (Dial, 1988), 8 by 8 grids for student use, masking tape to outline an 8 by 2 grid on floor, manipulatives to represent rice grains, and calculators.

Instructor’s Resource Guide, Chapter 14 Sandi Cooper|6 • Begin by sharing the book to the class.

• Consider the first 2 rows of the chessboard. Have students act out the story on an 8-by -2 grid on the floor using beans, blocks, or other manipulative materials to represent the grains of rice. What kinds of problems surface? How quickly does the wise man have over 100 grains of rice?

• Have the students fill in the amounts for the first two rows on a provided 8-by8 chessboard chart using calculators. Ask them to estimate when the wise man would have more than 500,000 grains of rice, over a million, etc.

• Let students check their estimates and experiment with the idea of doubling using calculators. Have them discover the constant feature of the calculator, if it has one.

• Ask the students if they would rather have the amount of rice given on the last day or all the rice received during the first 63 days. The memory of many fourfunction calculators will not allow the computation of 2 raised to the 64th power.

If this is the case, how do we make the decision? Once again, a pattern may need to be investigated. Compare Day 4 to the total of the first 3 days, Day 5 to total of previous 4 days, etc. Construct a table and based on that information, what decision should the wise man make?

• To close the activity, ask the students if they can suggest other ways the story could be used. Are there other mathematical topics that could be connected beyond estimation and understanding the idea of doubling?

10. The Math Links in this chapter provide students with online manipulatives. In class, or as an outside assignment, have students explore these web sites. The National Library of Virtual Manipulatives includes an entire section on Algebra for each grade level that includes online applets for Algebra Tiles and a Function Machine.

11. Have students work in groups to discuss items from Things to do: From What You've Read, and Things to do: Going Beyond this Book.

4. A chapter by Martin and Strutchens in Results from the Seventh Mathematics Assessment, highlights measurement items from the 7th National Assessment of Educational Progress (NAEP). Display some of these items and their results and discuss the implications for geometry instruction.

Student Textbook Activities 1. As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2. Have students try the paper folding activity in the Chapter 15 Snapshot of a Lesson.

Then have them review the lesson at www.learner.org and discuss the role of the process standards in this lesson.

3. Use PPT Slides #3-5 to highlight the key recommendations related to geometry from NCTM's Principles and Standards. These may also be found in the textbook in Figure 15-1 and in Appendix A. 4. Two Dutch educators, the van Hieles, developed a model for describing levels of geometric understanding. Provide additional information about this model. Sources of information include Chapter 10 of Mathematics for the Young Child, and in the Crowley chapter, in the NCTM 1987 Yearbook, Learning and Teaching Geometry, K-12 (see selected references). Figure 15-2 may be used to illustrate the stages children go through.

5. Several properties of shape are outlined in the chapter section on 2-D geometry. They are listed PPT Slide #15, Properties of Shape. Have the class approach the properties from the viewpoint of 3-D geometry. Are these same ideas important to the recognition of solids? Do any change? .S o n s

Instructor’s Resource Guide, Chapter 15 Sandi Cooper |3 6. There are many activities in this chapter related to the geometric processes of describing and sorting, constructing, exploring, and discovering. Have the students try some of these and analyze which level of the van Hiele model would apply.

7. Constructing 3-dimensional figures is a valuable learning activity. In the Classroom 151, Solid Mystery, 15-2,What can you Discover?, 15-3, Gumdrops and Toothpicks, and 154, Build your own Pyramid provide a variety of construction methods. Have students experiment with these construction techniques and identify other materials that can be used to construct figures.

8. In the Classroom 15-6, Less is Best and 15-8, Show my Sides include a game and a handson activity which encourage students to examine the number of sides of various figures.

Have students use pattern blocks and geoboards to complete these cards.

9. In the Classroom 15-7, How Many Lines? examines lines of symmetry. This activity can be extended to letters of the alphabet. Mirrors or Mira may also be introduced.

10. In the Classroom 15-9, How Many Degrees in a Quadrilateral allows students to examine angles. The activity may be adapted for triangles.

11. In the Classroom 15-10, Piezles reinforces parallel and perpendicular lines. Have students use pattern blocks to complete the activity.

12. In the Classroom 15-11, What’s my Altitude? provides a hands-on activity involving altitude. Have students complete the activity and discuss any insights they gained.

13. In the Classroom 15-5, Find Me, 15-12, Classify Me, 15-13, Can you Find It? and 15-15, Shape Maker provide activities for classifying and labeling shapes. Discuss the various insights that may be gained.

15. The Book Nook for Children, found in the text lists some children's books that may be used in the study of geometry. Encourage students to read and review these and others that may be appropriate.

Student Supplemental Activities 1. PPT Slides #21-22, Geoboard Quadrilaterals, presents a problem that involves the use of geoboards to explore the possible quadrilaterals that can be formed. This type of handson exploration illustrates the importance of this informal approach as opposed to the abstract, definitional approach often encountered. This problem incorporates many of the ideas about mathematics teaching and learning discussed at earlier points in the text.

Students are placed in a nonroutine problem-solving situation, using manipulative .S o n s

Instructor’s Resource Guide, Chapter 15 Sandi Cooper |4 materials in a hands-on setting to discover a geometry concept.

Materials: PPT Slides #21-22, Geoboards, rubber bands, Geoboard recording paper (see Appendix B).

• Pose problem using the provided transparency master. Answer any questions about the problem.

• Have students begin working in pairs to construct all 16 possible figures -working from geoboard to recording paper.

• If students finish before others, ask them if the 16 figures can be classified in any manner. How? • To close the activity, have students share the figures. You may want to have an overhead transparency of geoboard recording paper to be used in presenting the figures discovered.

• Ask at what grade level this problem could be used. Do we need to use the terminology noncongruent quadrilaterals?

Note that if geoboards are not available for use, the geoboard template provided in the text (Appendix B) can easily be used for exploring the problem.

2. Use pentominoes to investigate connections between area and perimeter. Each pentomino has an area of 5 square units, do they all have the same perimeter? What about the opposite situation? Suppose you have figures which all have a perimeter of 10 units, do they cover equal areas? Can you place the pentominoes together in such a way as to form a rectangle? What is its area? Students may use one-inch grid paper (Appendix B) as a work mat and color tiles to continue their investigation.

3. Allow students to work with different types of available computer software involving geometrical topics. Small groups working together in tackling technology can increase student willingness to experiment and experience what the software available can do.

Students need to experience cooperative learning and small group learning if these are methods we would like to see used in their classrooms. For example, Tessellmania! Is available from Dale Seymour Publications.

4. The topic of tessellations brings together geometry and art. The article "Thinking Geometrically" by Frederick and Williams (chapter annotated resources) provides all the necessary information, materials, and resources to allow an in-depth tessellation project on the web or an introductory experience for your students.

5. Have students examine the various commercial manipulative materials available for geometry. Many manipulative catalogs that students may also examine are available on the web. Brainstorm geometric concepts that may be reinforced by the various materials.

6. Encourage students to locate other pieces of children's literature which contribute to the study of geometry. For example, Grandfather Tang's Story by Ann Tompert, and The Greedy Triangle by Marilyn Burns. Both are available from Cuisenaire.

7. Demonstrate how geometry can be studied through real-life contexts and be multicultural.

For example, in the Chapter 15 annotated resources, Barkley and Cruz discuss beadwork .S o n s

Instructor’s Resource Guide, Chapter 15 Sandi Cooper |5 designs, Bradley discusses making Navajo blanket designs, Lipka, et al. discuss an Eskimo example, and Zaslavsky discusses round houses and American folk art.

Chapter 16 — Measurement What This Chapter Is About Measurement is an integral part of the elementary mathematics curriculum. Measurement is present in everyday life, helpful in learning other mathematical topics, useful in other areas of the curriculum, involves students, and can be approached through problem solving. Emphasized are the importance of identifying the attribute, choosing a unit of measurement, comparing the object to the unit, determining the number of units, and reporting the result. Issues related to each step, the role of formulas and measuring instruments are discussed. Connections between attributes, equivalencies, conversions, and measurement estimates are also addressed. Many suggestions and activities for including measurement in mathematics class are provided.

Student Objectives After reading the chapter, the students will be able to: 1. Summarize five reasons for teaching measurement.

2. Name the steps of measuring.

3. Define the attributes of measurement including length, capacity, weight, area, volume, angle, temperature, and time as well as provide examples of activities which promote their development.

4. Summarize the concepts related to measurement units.

5. Demonstrate measuring in units including standard units typically taught in particular elementary grades.

6. Demonstrate the use of measuring instruments as well as provide examples of activities which promote their development.

7. Demonstrate the use of measurement formulas as well as activities which promote their development.

8. Identify measurement equivalencies, conversions, estimation, and connections between attributes as well as provide examples of activities which promote their development.

Key Vocabulary Measuring is an important topic in the mathematics curriculum and is connected with many other topics of study within the subject. The terms below should be familiar to students and be used appropriately when discussing measurement ideas. measurement area conversion time conservation of area arbitrary unit equivalence capacity angle iteration length volume weight unitizing perimeter temperature chunking compare to a referent .S o n s

Instructor’s Resource Guide, Chapter 16 Sandi Cooper |2 Supplemental Lecture Topics 1. Use PPT Slide #3, The Measurement Standard, to highlight the key recommendations related to measurement from NCTM's Principles and Standards. These may also be found in the textbook in Figure 16-2 and in Appendix A. 2. A chapter by Martin and Strutchens in Results from the Seventh Mathematics Assessment, highlights measurement items from the 7th National Assessment of Educational Progress (NAEP). Display some of these items and their results and discuss the implications for measurement instruction.

3. In the April 2004 issue of Mathematics Teaching in the Middle School are a variety of articles about measurement. Young Mathematicians at Work provides professional development information on working with arrays. Use this information for supplemental lecture.

4. Chapter 11 of the NCTM book, Research Ideas for the Classroom: Early Childhood Mathematics, edited by Robert J. Jensen, highlights research results and recommendations concerning the teaching of measurement. Included is a discussion of Piaget's work with children's concepts of measurement and difficulties children have with measurement. Use this chapter to point out the importance of considering children's developmental levels when planning instruction.

Student Textbook Activities 1. As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #2. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2. Have students review the Chapter 16 Snapshot of a Lesson which may be viewed at www.learner.org. Have students identify the measurement attributes, tools, and units used in the segment. PPT Slide #21, Elementary Measurement, highlights examples of each.

3. Four reasons for including measurement in the elementary mathematics curriculum are discussed in the text. These reasons are outlined PPT Slide #4, Why Teach Measurement?. Divide students into four groups. Have each group focus on one of the reasons and brainstorm activities which would illustrate the reason. Conclude with a whole class discussion and sharing of the brainstormed activities.

4. PPT Slide #5, How to Teach Measurement, includes recommendations from a measurement study by Wilson and Osborne (1988). Share these recommendations and contrast them with textbooks' measurement lessons. Discuss how a textbook lesson can be supplemented or adapted. .S o n s

Instructor’s Resource Guide, Chapter 16 Sandi Cooper |3 5. PPT Slides #6-7, The Measurement Process, outlines the steps of the measurement process. Choose an attribute, such as length, and demonstrate how these steps may be carried out. For example, have groups of students use a ruler to measure their table or desk. Then have them select a nonstandard unit and measure the same table. Discuss their results and compare with the measurement steps from the text.

6. PPT Slides #8-15 include descriptions of the eight measurement attributes commonly taught in elementary school and these are discussed in Chapter 16. Highlight each attribute and refer students to Table 16-1 so they may see for each attribute which units are introduced in particular elementary grade levels.

7. A list of the concepts related to units that must be developed in learners over time is provided in the chapter. As the list is discussed, have students suggest activities that would help children in each area. Point out the activities provided in the text for further support of these concepts.

8. One of the concluding topics in Chapter 16 concerns estimating measurements. Begin with a review of Figure 16-1 which compares measuring and rounding. Then introduce three strategies for estimating measurements using PPT Slide #24, Estimating Measurements. For each strategy, engage the class in an estimation activity which illustrates the strategy. For example, to compare to a referent, have students use their known height to estimate the height of other students in the class. For chunking, have students use a known number of miles between two area cities to estimate the distance between the first city and a third city beyond the second city. For unitizing, have students measure a string that they estimate is the length of a desk or table in the classroom. Then have students cut a string that is four "tables" long.

9. In the text, three types of comparisons are discussed. In the Classroom 16-1, Perceptual Comparison of Lengths, 16-2, Direct Comparison to Length, and 16-3, Indirect Comparison of Length each illustrate one of the comparisons.

Have students try one of the activities and report what they discovered. Encourage students to find other connections.

17. The Book Nook for Children, found in the text provides a list of children's literature which may be used with the study of measurement. Read some of these books and have students develop measurement lessons to go with particular titles. Discuss how children's literature provides a context for solving mathematical problems.

Student Supplemental Activities 1. PPT Slides #26-27, Paint Problem presents a problem involving the measurement of volume. Students construct the figure using manipulative materials and are asked to consider how they arrived at their solution. This provides another chance for students to experience learning of the type to be used in elementary classrooms. Materials: PPT Slide #26 - Paint Problem, sets of Cuisenaire rods.

• Distribute the sets of rods so that each student has at least one of each size.

This may be an excellent opportunity to review the important points about distribution and storage of manipulative materials addressed in Chapter 3.

• Share the directions for the problem using the PPT Slide.

• Answer any questions about the construction of the rod tower. Encourage students to think about how they are solving the problem as they work toward a solution.

.S o n s

Instructor’s Resource Guide, Chapter 16 Sandi Cooper |5 • After students have worked and seem to have reached solutions, have students volunteer their solution methods. If no one presents the method provided on PPT Slide #27, share that as another possible approach.

• Encourage students to suggest other problems of this sort that could be posed using the manipulative materials provided.

2. PPT Slides #28-29, Calendars, provides an overhead to go with the following Connections to History information. Mathematics is created by humans. Our calendar evolved over many years and reflects changes initiated by different people. This example highlights how Roman superstition about numbers affects each of us today. Making "connections" between cultures and mathematics is interesting and often encourages students to engage in further study to learn more about these phenomena. PPT Slides #28-29 can be used to guide the discussion about the history of time measurement.

Connections to History: The first calendar was established in 46 BC by Julius Caesar.

The odd numbered months had 31 days and the even numbered months had 30 days.

February had 29 days in normal years and 30 days every fourth year. Augustus, an adopted son of Julius Caesar and the first Roman emperor named the eighth month after himself, but with 30 days it was considered unlucky. He wanted "his month" to be lucky, so he solved the problem by taking a day from February and giving it to August. This action created a calendar with three consecutive 31 day months. Now he was concerned about having three consecutive lucky months, so he decreed that the months September through December be changed to 30, 31, 30 and 31 days, respectively.

As you discuss the first calendar, several "almost" patterns are suggested. The odd numbered months (1st, 3rd, 5th, etc.) had 31 days and the even numbered months (4th, 6th, etc.) had 30 days. The second month was devoted to the devil and therefore had only 29 days. Our calendar has undergone many changes over the years. Here is one interesting series of changes that uses patterns as well as odd and even numbers. Are you superstitious? Do you think 13 is unlucky? Do you have a lucky number? In the Roman times, months with even numbers of days were believed to be unlucky. Months with an odd number of days were thought to bring good luck.

3. Measurement is a topic that is closely related to the science subject area. It might be interesting to work together with a science methods instructor to devise an activity that would involve both subject areas and actively involve students in the integrated experience.

4. Have students examine elementary textbooks and identify grade levels when particular units are introduced. Compare these findings with Table 16-1. In addition have students examine the presentation of metric versus customary units.

5. Many measurement instruments can be homemade. Not only are they inexpensive, but the students often gain understanding of the units by making the instruments. Share ideas for homemade instruments with students. Ideas may be found in the sources listed below, encourage students to think of others. For example: 1-inch ceramic tiles are inexpensive .S o n s

Instructor’s Resource Guide, Chapter 16 Sandi Cooper |6 from carpet and tile stores. Measuring tapes may be cut from a vinyl table cloth. Lumber yards sell four foot strips of wood lath very inexpensively. Soft drink cups from fast food cups often come in cup, pint, etc. sizes. In the text, Appendix B also contains masters that may be used with measurement activities. Here are some classics: • Shaw, J.(1983). Let's Do It Student-made Measuring Tools. Arithmetic Teacher, November.

• Thompson, C. & Van de Walle, J. (1985). Let's Do It Learning About Rulers and Measuring. Arithmetic Teacher. April.

The book, Investigating Real Data in the Classroom, also provides important insight into classrooms. Use these resources to provide additional information for students.

Student Textbook Activities 1. As an advance organizer, have students read the Focus Questions, found at the beginning of the chapter and PPT Slide #3. Discuss what they already know and what they want to learn more about. Have them share any other questions they have about this chapter.

2. Have students review the Chapter 17 Snapshot of a Lesson. It may be viewed at www.mmmproject.org. Discuss which reasons for teaching statistics and probability on are being illustrated.

3. There are several reasons why statistics and probability topics should be part of the elementary mathematics curriculum. PPT Slide #4, Why Teach Statistics and Probability? highlights the four reasons discussed in the text. Space has been provided so activities brainstormed by students for each reason may be listed. In addition, encourage students to develop other reasons for studying statistics and probability.

4. Chapter 17 lists the nine types of graphs and plots typically used by elementary school students. Divide students into nine groups. Each group should review the text concerning that type of graph and report to the rest of the class. Encourage students to find examples of each of the nine types in elementary textbooks and display them on a class bulletin board. .S o n s

Instructor’s Resource Guide, Chapter 17 Sandi Cooper |3 5. PPT Slide #5, Three Steps of Data Analysis, provides the three steps of data analysis discussed in the text. Choose a question or problem to be answered (In the Classroom 17-1 is a good source for ideas) to model the process which is suggested. Encourage students to bring in their own examples.

6. Review the concept of descriptive statistics with students. PPT Slide #18, Analyzing Data: Descriptive Statistics presents a brief definition for the statistics typically introduced in the elementary school. Have students use a concrete material to model each definition. Space has been provided so that students may add real-life problems that elementary students might solve involving each of the descriptive statistics.

7. There are several important terms related to the concept of probability. The terms discussed in Chapter 17 are listed on PPT Slide #22, Probability. Use some simple probability experiments with dice or spinners to demonstrate each term. Have students design additional experiments and use the terms to describe their experiment.

8. In the Classroom 17-1, Let’s Find Out and 17-2, Sharing Data show how children can collect and display data to answer real-life problems or use real-life data to answer questions. Have students locate or make up additional problems which would interest elementary children.

9. In the Classroom 17-3, Peanuts and 17-4, What’s the Average? give experiences with descriptive statistics. Have students work through these activities and discuss their usefulness with children.

10. In the Classroom 17-5, What are the Chances?, 17-6, What’s more Likely?, 17-7, Rolling and Recording, 17-8, Are you a Winner?, and 17-9, Can you make Predictions? introduce a variety of probability activities for children. Have students examine and compare the activities. Discuss how they might be included in a probability unit. Have students select a particular activity, carry it out, and present findings to the class.

11. Have students collect a set of data. Then have them examine the graphs presented in Figure 17-17. Have various groups display the data using the variety of graphs. Discuss how it is sometimes useful to display a set of data in more than one way. Students can experiment with taking one type of graph, such as a bar graph, and changing the scale to make the display look different.

12. Have students review the averages-mean, median, and mode in the text. Then have students use some of the concrete materials described (blocks, paper strips, cards, etc.) to model these averages. Discuss other materials that could be used to model the averages concretely.

13. The Book Nook for Children, found in the text lists some children's books which may be used in the study of probability and statistics. Encourage students to read and review these and others that may be appropriate. .S o n s

Instructor’s Resource Guide, Chapter 17 Sandi Cooper |4 Student Supplemental Activities 1. PPT Slides #29-31, Mystery Bags, presents a problem which involves the use of manipulatives to introduce the basic ideas of probability. Students try to predict the contents of the bag based on samples taken from the container. The problem provides an opportunity for students to participate in a probability experiment. As a part of an activity of this type, there is opportunity to introduce the correct terminology and connect it to a concrete example. Students are involved in trying to predict the contents based on random samples taken of the contents. Materials: PPT Slides #29-31, color tiles, paper lunch bags.

• Have each student prepare a mystery tile bag as outlined on the overhead.

• Have students deposit their bag into a large box or other container. Distribute the bags randomly so that each student receives a bag.

• Review the remaining directions on the overhead for the sampling procedures and questions of interest. Answer any questions about the process.

• Allow time for students to conduct their sampling experiment and record the results. To make the recording process easier, you may want to construct a worksheet with a table to organize their results as well as additional questions which may be of interest.

• Have students open their bag of tiles and compare their results with the actual color totals contained in the bag. Discuss the results. How many were correct in their hypothesis? Why did some results not match the actual situation? How do we improve our guesses of color distribution? The discussion can then turn to the ideas of probability based in this situation. Given the actual contents of the bag, what is the probability the tile drawn would be red? What was the probability based on your experimentation?

This situation can then be used to discuss terms, such as sample space, randomness, and equally likely events. Have students think about the range of activities that can be provided to help children at all levels learn probability and statistics concepts.

2. Most students will not be familiar with the box-and-whisker plots and the stem-and-leaf plots discussed in Chapter 17. Provide them with experience in what these representations are and how to construct each type. This is an opportunity for the students to gather data in an area of interest and participate in forming an appropriate representation. The use of technology can be integrated into the discussion through access to a piece of elementary graphing software, for example The Graph Club by Tom Snyder Productions, that allow students to easily experiment with a variety of data representations.

3. Have students consider the question of the average number of chocolate chips in a given brand of cookies, or a comparison of chips contained in several brands. This same question could be asked using snack-size bags or boxes of raisins, M&M's, conversation hearts, candy corn or other material to fit the season or interests of the student group.

Other interesting questions which involve the students in actively gathering data and determining the method of analysis and interpreting their results can be developed. .S o n s

Instructor’s Resource Guide, Chapter 17 Sandi Cooper |5 4. Have students bring in examples of data use from current publications: newspapers, magazines, or books. Divide the class into small groups to share their samples of data presentations. After each student in the group has share his/her contribution, have the group develop an activity for classroom use based on one of the examples shared. It might be challenging to have the students develop two activities based on the same sample, one appropriate for lower grades and one appropriate for upper grades. Have each small group share their ideas through presentations to the larger group.

5. NCTM's Navigating through Data Analysis and Probability for grades Pk-2, 3-5, and 6-8 and Addenda books, Making Sense of Data and Dealing with Data and Chance provide activities for developing the concepts of statistics and probability. Have students work together to review these books and present an activity to the class.

Compare the presentation of probability and statistics in these units with those found in elementary textbooks.

7. Teacher resource materials for data and graphing are available from several other sources. The United States Census Bureau publishes free materials for teachers. USA Today newspaper has teacher resource materials available with the purchase of classroom subscriptions. See additional resources for addresses. Make these resources available for students to review.

8. The concept of fairness can be developed through games. The chapter by Bright, Harvey and Wheeler in the Chapter 17 Selected References provides ideas for using games to develop the concept.

9. The computer is a valuable tool when studying probability and statistics. It can be used to develop various types of graphs and plots quickly and easily. It can also be used to simulate probability experiments and collect and organize data for example, Probability Tool Kit by Ventura Educational Systems. Have students review various software pieces which can be used with elementary students.

10. Marilyn Burns offers several activities that develop the concepts of probability. For examples, see her book, A Collection of Math Lessons From Grades 6-8, and the video, Mathematics: for Middle School, Part 1. Both are available from Cuisenaire Company.
