About this 3 minute timer
Use this 3 minute timer for the in-between moments of the day: a movement break, a quick review round, or a heads-up before stations rotate. Three minutes feels generous to students but keeps the lesson moving.
Start it with the space bar from anywhere in the room. The timer keeps accurate time even when you switch tabs to show slides, and a sound plays at zero.
Need something different? The full tool lets you set anything you like: classroom timer.
