Great work, everyone.
What a 25 minute timer is good for in class
- A focus block for older students, followed by a 5-minute break (the pattern many study routines use).
- A full writing session: plan, draft and reread.
- A unit quiz with time to check answers.
Running one of these every day? See the test timer and quiet timer for set-up tips.
How the 25 minute 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 25:00 down to 12:30 | More than half the time left |
| Yellow | From 12:30 down to 5:00 | Less than half left |
| Red | The last 5 minutes | Final 20 percent |
Sounds
- A soft two-note warning chime at 1:00 left (you can turn it off).
- 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).
Splitting 25 minutes into parts
For a long session, Station rotations can split the time into parts with a short break between them. Some ways to divide 25 minutes of work, with 2 minute breaks added between parts:
| Parts | Each | Breaks | Total |
|---|---|---|---|
| 2 | 12 min | 2 min | 26:00 |
| 3 | 8 min | 4 min | 28:00 |
| 4 | 6 min | 6 min | 30:00 |
Questions teachers ask
Can I use this for study blocks with breaks?
Yes. Turn on Station rotations, set stations to the number of blocks and switch time to the break length (up to 5 minutes). The break shows as a purple Switch! screen.
How do I start a 25 minute timer?
This page is already set to 25:00. 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 25 minute timer turn yellow and red?
It turns yellow with 12:30 left and red with 5:00 left. You can turn colour changes off so the disc stays green.
What sounds does the 25 minute timer make?
A warning chime at 1:00 left, then 3-2-1 blips and an end chime. Sound only starts after you press a button, and the speaker button mutes everything.
