Module 2
Place Value and Problem Solving with Units of Measure
Module 2 Lessons:
Topic A: Time Measurement and Problem Solving
Lesson 1: Explore time as a continuous measurement using a stopwatch.
Lesson 2: Relate skip-counting by fives on the clock and telling time to a continuous measurement model, the number line.
Lesson 3: Count by fives and ones on the number line as a strategy to tell time to the nearest minute on the clock.
Lesson 4: Solve word problems involving time intervals within 1 hour by counting backward and forward using the number line and clock.
Lesson 5: Solve word problems involving time intervals within 1 hour by adding and subtracting on the number line.
Topic B: Measuring Weight and Liquid Volume in Metric Units
Lesson 6: Build and decompose a kilogram to reason about the size and weight of 1 kilogram, 100 grams, 10 grams, and 1 gram.
Lesson 7: Develop estimation strategies by reasoning about the weight in kilograms of a series of familiar objects to establish mental benchmark measures.
Lesson 8: Solve one-step word problems involving metric weights within 100 and estimate to reason about solutions.
Lesson 9: Decompose a liter to reason about the size of 1 liter, 100 milliliters, 10 milliliters, and 1 milliliter.
Lesson 10: Estimate and measure liquid volume in liters and milliliters using the vertical number lien.
Lesson 11: Solve mixed word problems involving all four operations with grams, kilograms, liters, and milliliters given in the same units.
Topic C: Rounding to the Nearest Ten and Hundred
Lesson 6: Build and decompose a kilogram to reason about the size and weight of 1 kilogram, 100 grams, 10 grams, and 1 gram.
Lesson 7: Develop estimation strategies by reasoning about the weight in kilograms of a series of familiar objects to establish mental benchmark measures.
Lesson 8: Solve one-step word problems involving metric weights within 100 and estimate to reason about solutions.

Topic D: Two- and Three-Digit Measurement Addition Using the Standard Algorithm
Lesson 15: Add measurements using the standard algorithm to compose larger units once.
Lesson 16: Add measurements using the standard algorithm to compose larger units twice.
Lesson 17: Estimate sums by rounding and apply to solve measurement word problems.
Topic E: Two- and Three-Digit Measurement Subtraction Using the Standard Algorithm
Lesson 18: Decompose once to subtract measurements including three-digit minuends with zeros in the tens or ones place.
Lesson 19: Decompose twice to subtract measurements including three-digit minuends with zeros in the tens and ones places.
Lesson 20: Estimate differences by rounding and apply to solve measurement word problems.
Lesson 21: Estimate sums and differences of measurements by rounding, and then solve mixed word problems.
