You and your students can see at a glance how much time remains for testing or classroom events. Just set this battery-operated timer to the amount of time a task requires; the red indicator moves as time passes and the clock beeps when time is up. Stand it on a desk or table for self-monitored activities, or hang it on a wall for classroom and group tasks. You can choose between silent operation and an audible signal to indicate when times up. Requires one AA battery (not included).
