A classroom timer students can read from anywhere
A shared clock takes the pressure off the teacher and gives every student the same, visible finish line. This classroom timer is designed for projection: oversized tabular digits, a simple visual ring, and high contrast that stays readable on a projector or interactive whiteboard.
Set the activity name, choose a quick preset, press Start, and use fullscreen when the timer is the only thing the room needs to see. As time gets short, the visual cue shifts from calm teal to amber and then red—giving students a quiet, predictable prompt to wrap up.
How to use this free classroom timer
- Choose a ready-made duration for a transition, partner discussion, writing sprint, or class period.
- Add a clear label such as “Science stations” or “Exit ticket” so students know what the time is for.
- Click Start, then select fullscreen (or press F) before you project the display.
- Pause, restart, or add a minute when the lesson takes an unexpected but useful turn.
Built for everyday teaching moments
Use a one- or two-minute countdown to settle the room or move between stations. Give a five-minute warning for pair work, ten minutes for a quick write, or a full class period for independent practice. When the activity has no fixed endpoint, switch to the stopwatch and let the class see time accumulate together.
The timer stays intentionally uncluttered. There are no ads competing with your lesson, no account to create before class starts, and no busy dashboard for students to decode.
