**2.1 Measurement—Time and Mass**

**Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.**

**Measurement and Data 3.MD**

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.

6 Excludes compound units such as cm3 and finding the geometric volume of a container.

7 Excludes multiplicative comparison problems (problems involving notions of “times as much”; see Glossary, Table 2).

**Essential questions**

• What do you need to know to accurately tell time to the nearest minute?

• How can you use a number line to show elapsed time when solving a word problem?

• When solving a word problem, how can you measure and estimate the mass/volume of objects?
