MA19.4.22

Use the four operations to solve measurement word problems with distance, intervals of time, liquid volume, mass of objects, and money.

Unpacked Content

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:
  • Solve measurement word problems
  • Involving distance, intervals of time, liquid volume, mass, and money.
  • Involving measurement conversion of larger units to a smaller unit.
  • Involving simple fractions or decimals.
  • Using diagrams to represent measurement quantities and solutions.

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.
