It’s easy to time classroom activities...with an ingenious timer that actually shows students how much time is left! Just slide the red dial to select the amount of time you want to track, then watch as it slowly disappears—and you’ll hear a beep when time is up! The 60-minute timer is magnetic and wall-mountable and even has a built-in stand...so you can use it anywhere! Timer measures 7 1/2" x 7 1/2". Requires 2 “AA” batteries (not included).
