Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
Grade 3
3.MD.1.
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
3.MD.2.
Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).6 Add, subtract, multiply, or divide to solve onestep word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.[Excludes multiplicative comparison problems (problems involving notions of “times as much”; see Glossary, Table 2)]
