time interval

Standard 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, for example, by representing the problem on a number line diagram. Standard 3.MD.2 Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), milliliters (ml), and liters (l). (Excludes compound units such as cubic centimeters (cc or cm 3 ) and finding the geometric volume of a container). Add, subtract, multiply, or divide to solve one-step word problems involving masses of objects or volumes of liquids that are given in the same units, for example, by using drawings (such as a beaker with a measurement scale) to represent the problem. (Excludes multiplicative comparison problems.)

Application Task

3.MD.1

Draw the hands on each clock to show the time. (DOK 1)

Paul recorded his reading minutes every night. On Wednesday, he began reading at 6:10. He read for 35 minutes. At what time did Paul finish reading? Draw clocks to show the time that he started reading and the time that he stopped reading.
