Beat the Clock: Time & Elapsed Time

Math, Unit 7, Topic 7.2. At the track, students read and set a geared clock and move its hands from a start time to an end time, draw elapsed time on a time track (a rock hop to the next hour, a hill for each whole hour, a jump for the minutes left), find end times and count back to start times, trade 60 minutes for 1 hour, and subtract times with regrouping.
