Adding and subtracting time intervals can be tricky! In this lesson, students will review what it means to add and subtract time intervals. They will then practice writing their own story problems that involve time intervals, and place their story problems in a large bucket. Finally, they will draw from the bucket to answer their classmates story problems.
