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.

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.
