# Teaching 4.MD.A.2 – Use the Four Operations to Solve Problems Involving Measurement and Conversion

## Measurement & Data – 4th Grade

#### Solve problems involving measurement and conversion of measurements.

CCSS.Math.Content.4.MD.A.2
Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

Teacher Notes
Students should know some benchmarks for units of measurement and when measuring objects, we must decide which unit (a smaller or larger unit) is most appropriate for expressing measurements.

Student Knowledge Goals
I know there are different ways we can display measurements.
I know different tools and strategies that you can use to solve measurement problems.
I understand measurement concepts helps us communicate mathematically and make sense of real-life situations.
I can use +, -, x, and ÷ to solve word problems.
I can solve measurement word problems that include whole numbers, fractions, and decimals.
I can convert larger units into equivalent smaller units to solve a problem.
