A quick countdown for wait time, rapid-fire answers and game rounds.
Activity

Station rotations
4 × 10 seconds, 60s to switch · 10 seconds total
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.
What a 10 second timer is good for in class
- Wait time after a question, so every student has a moment to think before hands go up.
- Rapid-fire rounds: name a word that rhymes, a fact you remember, or a multiple of 7 before the disc empties.
- A ten-second freeze at the end of a dance break so the room settles before the next instruction.
Running one of these every day? See the brain break timer and transition timer for set-up tips.
How the 10 second timer looks on the board
The disc starts full and shrinks clockwise. Its colour tells the class how much time is left, even from the back of the room:
| Disc | Clock shows | Meaning |
|---|---|---|
| Green | From 0:10 down to 0:05 | More than half the time left |
| Yellow | From 0:05 down to 0:02 | Less than half left |
| Red | The last 2 seconds | Final 20 percent |
Sounds
- No 1-minute warning chime: it only plays on timers longer than 90 seconds.
- Three short blips at 0:03, 0:02 and 0:01.
- A rising end chime, “Time's up!” on the board and a burst of confetti (skipped if your device is set to reduce motion).
Running 10 second timer rounds back to back
Turn on Station rotations to repeat the 10 second timer as rounds, with a short rest between them. With a 15 second rest:
| Rounds | Work | Rest | Total |
|---|---|---|---|
| 3 | 30 s | 30 s | 1:00 |
| 5 | 50 s | 1 min | 1:50 |
| 8 | 1 min 20 s | 1 min 45 s | 3:05 |
Questions teachers ask
Is 10 seconds long enough to be useful?
Yes, for thinking rather than doing. Ten seconds of silent wait time after a question gives slower processors a fair start, and the shrinking disc stops the quickest hands from jumping in early.
How do I start a 10 second timer?
This page is already set to 0:10. Press Start or the space bar. To put it on the board, press Show to class: the controls disappear and the timer fills the screen. Tap the screen to pause, press Esc to exit.
When does the 10 second timer turn yellow and red?
It turns yellow with 0:05 left and red with 0:02 left. You can turn colour changes off so the disc stays green.
What sounds does the 10 second timer make?
No warning chime (the timer is too short for one), but 3-2-1 blips and an end chime. Sound only starts after you press a button, and the speaker button mutes everything.
