Press Show to class for the board or projector. The disc shrinks and turns yellow, then red. Space starts and pauses. The screen stays awake while the timer runs.
Time's up!
Great work, everyone.
Why use a full screen timer
Show to class mode turns this page into a board display: no menus, no buttons, no ads, just the words, the disc and very large digits. It fills the screen, keeps the screen awake while running, and pauses when you tap it, which is handy on an interactive whiteboard.
How to run it
- Set the time and the words on the board.
- Press Show to class. The browser switches to full screen and hides everything except the timer.
- Tap the screen (or press the space bar) to start and pause.
- Press Esc, or the small Exit button in the corner, to return to the controls.
Tips
- On a wide projector the disc and digits sit side by side; on a tall screen they stack.
- Dark mode is easier to read on some projectors.
- If full screen isn't allowed (some phones), the board view still hides all the controls.
Questions teachers ask
How do I exit full screen?
Press Esc, or tap the Exit button in the bottom corner. On touch screens, a single tap pauses or resumes the timer instead of exiting.
Does it work on a smartboard?
Yes. Open the page in the board's browser. Tapping the board pauses and resumes the timer.
Are there ads on the full screen view?
No. The board view never shows ads or anything other than the timer.
