Knowledge
Students know:
- Relative sizes of units within one system of measurement.
- Strategies to solve word problems involving the four operations.
- Measurement units in the same system are multiplicatively related.
Skills
Students are able to:
Note: Quantities and operations are limited to grade 4 standard expectations.
- Solve measurement word problems
- Involving distance, intervals of time, liquid volume, mass, and money.
- Involving measurement conversion of larger units to a smaller unit.

Note: Quantities and operations are limited to grade 4 standard expectations.
Understanding
Students understand that:
- Relationships among units within a system of measurement are multiplicative comparisons.
- The size of the unit of measurement and the number of units are inversely related.
- Addition and subtraction of measurements require measurements in the same unit and that the common unit is maintained in the answer.
