Begin with the End in Mind The theme or â&#x20AC;&#x153;big ideasâ&#x20AC;? for this PBL: Students will explore parallel lines and transversals. TEKS/SEs that students will learn in the PBL: (G.3) Geometric structure. The student applies logical reasoning to justify and prove mathematical statements. The student is expected to: (B) construct and justify statements about geometric figures and their properties. (G.9) Congruence and the geometry of size. The student analyzes properties and describes relationships in geometric figures. The student is expected to: (A) formulate and test conjectures about the properties of parallel and perpendicular lines based on explorations and concrete models. Key performance indicators students will develop in this PBL: Develop vocabulary (corresponding angles, distance from a point to a line, parallel lines, bisect, rhombus, angle bisector, conjecture, vertex), find patterns, create rules for bisecting angles, write and solve word problems 21st century skills that students will practice in this PBL: www.21stcenturyskills.org Critical thinking, problem solving, collaboration, communication STEM career connections and real world applications of content learned in this PBL:

Careers: Civil Engineering, Construction, Government/Political Science Connections: Roadway design impacts workers, land owners, design engineers, and city planners.

9. Finally, the rancher is debating putting a billboard advertisement up along the road. If a person is traveling on CR131N and hits the northwest corner of Tract A heading east at 50 miles an hour, how long will he be on the road before he is at the spot mentioned in #7 above? 10. A diagram showing Tract A, CR131N, CR131S, the gas lines, distances from any intersections, and any other point of reference must be created and formally presented to your boss.

Explore Activity Have the students work in their teams to complete the Explore Activity (see below). Upon completion of the Explore Activity, have the students investigate the size of an acre, hectare, and other measurements of land. Have the students create a poster with 3 land-based word problems that require the use of angle measurements, bisectors, and conversions to solve. Upon completion, proof the students’ problems and solutions and use a gallery walk format with the students sending them around to work all problems…including their own. Debrief the activity with the students Explore Activity Products and Artifacts Explore Activity, poster, word problems and solutions, gallery walk with completed problems Explore Activity Materials/Equipment Attached Explore Guide, Internet Access, Graph Paper, Protractors, Rulers, Pencils/Pens, Notebook Paper Explore Activity Resources Explore Activity http://www.frentzandsons.com/Hardware%20References/landmeasurements.htm http://www.answers.com/topic/hectare Explain Activity Have the students present their findings from the Explore Activity to the rest of the class. Upon the conclusion of all group presentations, have the students discuss observations, ideas, questions, and hypotheses with the rest of the class. Act as the facilitator, clear up any misunderstandings, and broaden the students’ vocabulary base. During the discussion, add to an existing word wall or have students add to their vocabulary journals. The students can then refer back to these during the project. Have the students reflect in their journal regarding the concepts and vocabulary that have been discussed during the Explain phase. Have the students apply their learning by individually creating a rough sketch of how to solve the problem in their journals. Upon completion, provide the students with time to re-assemble as a group and discuss the processes they feel will lead them to the final solution. © 2008 Transformation 2013

Are new roads or highways being built in your area? See if one of the foremen or engineers can visit your class to discuss the road design process. Explain Activity Products and Artifacts Word Wall, journal reflection, notes Explain Activity Materials/Equipment Journal, pencil, word wall, construction paper, markers Explain Activity Resources None Elaborate Activity Students were introduced to the design challenge at the end of the engage activity and have been exploring possible drawings for their project. Time should be taken to expand concepts being discussed and mathematics being discovered. Provide the students with opportunities for practice of the concepts that they will be using to solve the challenge. Constructions required for this project will either be introduced or reviewed. Give the students time to practice their construction skills. Add additional constructions that may be related to topics that relate to those addressed in the Explore and Explain steps. Once the concepts are solidified, re-introduce the problem to the students and provide them with the opportunity to solve the problem and create a presentation of their results. Share the rubric with your students so they know the expectations for the project.

Evaluate Activity Have students post their drawings around the room. Using a gallery walk with a docent, have students examine the other groups’ work. Regroup and discuss which groups excelled at meeting the different criteria. Class should vote for the “best” team and explain what sets them apart from the other designs. Students will present their drawings to the class or a teacher-selected panel with grading from the assigned rubric.

B. Use the segments from Section A to construct a line segment with length AB + CD. C. Use the segments from Section A to construct a line segment with length AB + 2EF â&#x20AC;&#x201C; CD D. Construct duplicates of the following angles: 1

2.

E. Draw 2 Acute angles. Construct a third angle with a measure equal to the sum of the measures of the first two angles. F. Draw an equilateral triangle using the following line segment: A B G. Construct triangle ABC with segment OU connecting the midpoint O of AB and the midpoint U of AC. H. Construct a 900 angle, a 450 angle, and a 1350 angle. I. Draw a large acute triangle. Bisect each of the angles making sure the bisector crosses the opposite side of the triangle. Construct an altitude from one vertex and a median from another vertex. Explain anything you might notice about any of the lines. If you drew a different triangle would the same things happen? J. Draw a large scalene obtuse triangle ABC with angle B the obtuse angle. Construct the angle bisector BR, the median BM, and the altitude BS. What order are the letters M, R, and S, on the segment AC? Will this order always be the same (no matter the size of angle B)? Write a conjecture.
