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.
Telling time is not enough. Students need to understand and apply strategies to solve elapsed time situations that are real world. This knowledge is essential in creating a deep understanding of using clocks as a tool to measure the passing of time.
Students that can write their own story problems, and create math situations that require thought and perseverance to solve, are students that understand. This engaging activity reviews all of the third grade concepts and creates a review packet as well!
