Before This Module

Overview

Grade 2 Modules 1 and 2

Place Value Concepts Through Metric Measurement

In grade 2, students describe and apply place value concepts to two- and three-digit numbers. They count and bundle ones, tens, and hundreds up to 1,000. Students read and write numbers in standard, unit, and expanded forms and apply place value understanding to add and subtract two- and three-digit numbers by using a variety of strategies. Simplifying strategies consist of composing and decomposing tens and hundreds to make problems easier to compute mentally and developing various written methods to record student thinking.

Topic A Understanding Place Value Concepts Through Metric Measurement Students estimate and measure weight and liquid volume by using grams, kilograms, liters, and milliliters. Familiar concepts, such as composing and decomposing place value units, are applied to the relationship between the smaller unit (gram or milliliter) and the unit that represents 1,000 (kilogram or liter). The number line is applied as a familiar model for understanding how to read circular and vertical measurement scales. Students solve one-step word problems that have measurement contexts.

Students also estimate and measure length by using a variety of tools and units in the customary and metric systems of measurement.

Grade 3 uses familiar place value concepts to expand student understanding of metric measurement of weight and liquid volume and to develop fluency in addition and subtraction within 1,000.

Topic B Rounding to the Nearest Ten and Hundred Reading temperatures on a thermometer provides an initial context for students to round to the nearest ten or hundred. To round a number, students determine the two consecutive tens or hundreds that the number is between and then determine which ten or hundred is closer by thinking about the number in relation to the halfway mark. The number line, when presented vertically, provides a new perspective on a familiar tool and is used to help students to round numbers. Students then apply their rounding skills to estimate sums and differences.

Topic C

After This Module

Simplifying Strategies to Find Sums and Differences Students apply their knowledge of the vertical number line to the scale on a scaled bar graph. They represent data in a scaled bar graph and solve addition and subtraction problems related to scaled bar graphs. They explore a variety of addition and subtraction strategies based on place value, the properties of operations, and the relationship between addition and subtraction. The strategies include adding and subtracting like units, making the next ten or hundred, taking from a ten or hundred, and using compensation. Emphasis is placed on thinking flexibly and building toward the use of mental math. Throughout the topic, students share and critique solution strategies for addition and subtraction problems and explain how their choice in strategy helps them to add or subtract efficiently.

Grade 4 Module 1 In grade 4, students apply their understanding of measurement units to convert weight, liquid volume, and length measurements from larger units to smaller units.

Students generalize place value and rounding concepts and relationships to larger, multi-digit numbers. They add and subtract multi-digit numbers by using the standard algorithms for addition and subtraction.

Topic D Two- and Three-Digit Measurement Addition and Subtraction Topic D is devoted to using place value to model the standard algorithm for addition and the standard algorithm for subtraction with numbers within 1,000. Students use vertical form in conjunction with a place value model to allow them to better recognize like units and the value of numbers when they are not on the place value chart. Representations move from concrete to pictorial to abstract, and they serve to solidify the understanding of the composition and decomposition of units. Students learn that although standard algorithms work for all problems, there might be a more efficient strategy to use depending on the numbers being added or subtracted. Students apply learning from topic C to analyze addition and subtraction problems, many with a measurement context, and determine whether to use a simplifying strategy or the place value chart and standard algorithm for each.

Students begin the topic by using the place value chart and the standard algorithm for addition. They manipulate place value disks on a chart to represent the algorithm and record their work in vertical form. The concrete place value disks are then replaced with drawings on place value charts, where dots are used to represent the addends and the sum. Students bundle once and then twice and record the composition of new units vertically in different ways.

For subtraction, students manipulate place value disks on a chart before transitioning to drawing on the place value chart. Students get ready to subtract by checking each place value and unbundling as necessary before performing any subtractions. They record their work in vertical form with one and then two decompositions. Before subtracting, students estimate the answer by rounding the minuend and subtrahend and finding their difference.

After subtracting, students use their estimate to assess the reasonableness of their answer.

Students see that they can use addition to check their subtraction.

Within the topic, students apply their computation skills to solve one-step addition and subtraction word problems involving measurement contexts. To conclude the topic, students solve two-step word problems involving all four operations.

In future lessons, fluency activities provide ongoing practice toward developing fluency with addition and subtraction strategies and algorithms. Use of the standard algorithms for addition and subtraction extends to numbers within 1,000,000 in grade 4 module 1 and to decimals in grade 5.

Place value disks help to show addition and to transition to the vertical form.

The standard algorithm is a process I can use to add like units. When I need to make a new unit, I record the new group on the line.

Instead of using actual place value disks, I can draw dots on a place value chart to represent the disks. When I need to make a new unit, there are different ways I can record it. New groups below shows the renaming on the line. Totals below shows the total for each place value below the addends.

Representing a subtraction problem by using dots on the place value chart helps me to see how to get ready to subtract. Sometimes I need to unbundle twice to be ready to subtract. I can see this on the place value chart and in vertical form. For some problems, another subtraction strategy is a better choice. After I subtract, I can check my answer by using addition.
