Module 2: Place value and problem solving with units of measure
Students will be able to:
|
- Build and decompose a kilogram to reason about the size and weight of 1 kilogram, 100 grams, 10 grams, and 1 gram
- Develop estimation strategies by reasoning about the weight in kilograms of a series of familiar objects to establish mental benchmark measures
- Solve one-step word problems involving metric weights within 100 and estimate to reason about solutions
- Decompose a liter to reason about the size of 1 liter, 100 milliliters, 10 milliliters, and 1 milliliter
- Estimate and measure liquid volume in liters and milliliters using the vertical number line
- Solve mixed word problems involving all four operations with grams, kilograms, liters, and milliliters given in the same units
- Round two-digit measurements to the nearest ten on the vertical number line
- Round two- and three-digit numbers to the nearest ten on the vertical number line
- Round to the nearest hundred on the vertical number line

Round 155 to the nearest ten and nearest hundred.
- Add measurements using the standard algorithm to compose larger units once and twice
- Estimate sums by rounding and apply to solve measurement word problems
- Decompose once to subtract measurements including three-digit minuends with zeros in the tens or ones place
- Decompose twice to subtract measurements including three-digit minuends with zeros in the tens and ones places
- Estimate sums and differences of measurements by rounding, and then solve mixed word problems
