About classroom timers
Visual timers help students stay focused and manage classroom time effectively. Research shows that students work more productively when they can see how much time remains for an activity. Our free classroom timer features a large, easy-to-read display that's visible from anywhere in the classroom.
Each timer includes an audio alert when time is up, a full-screen mode for projecting on smartboards, and a clean design that won't distract students. Use the timer for brain breaks, station rotations, timed tests, silent reading, group work, and classroom transitions.
Frequently asked questions
Can I project the timer on a smartboard?
Yes. Use full-screen mode to display the timer on any smartboard or projector. The large numbers are readable from the back of the classroom.
What timer length works best for brain breaks?
Research suggests 1–3 minute brain breaks between activities. A 2-minute timer is ideal for quick movement or stretching, while 3 minutes allows for a short game or breathing exercise.
Does the alarm work on school Chromebooks?
Yes. Our timer works in any modern browser including Chrome on Chromebooks. The audio alert plays through the device speakers when the countdown reaches zero.
