Classroom Timer – Big Projector Countdown
5:00
Ready
Your screen may turn off — keep it awake.
Keys: Space start/pause, R reset, + / − one minute, F focus. Shortcuts work when the timer is focused.
Press F (or the Focus button) for projector view: the timer fills the screen. Press F or Esc to leave it.
Put this timer on the projector or the whiteboard and the whole room can see how much time is left. High contrast is on from the start so the digits stay readable from the back row, and the alarm is set to override silent mode so you hear it at the end. It runs in any browser, including school Chromebooks, with nothing to install and no sign-up. Pick a preset or adjust by a minute.
Ways teachers use it
- Transitions: a 2 or 3 minute countdown to tidy up and get ready for the next activity.
- Group work and stations, with the time left visible from every desk.
- Timed tests and quizzes, with the alarm set to override silent mode.
- Reading time, brain breaks and clean-up on a Chromebook or interactive whiteboard.
