How the 50 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 50:00 down to 25:00 | More than half the time left |
| Yellow | From 25:00 down to 10:00 | Less than half left |
| Red | The last 10 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 50 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 50 minutes of work, with 2 minute breaks added between parts:
| Parts | Each | Breaks | Total |
|---|---|---|---|
| 2 | 25 min | 2 min | 52:00 |
| 3 | 16 min | 4 min | 52:00 |
| 4 | 12 min | 6 min | 54:00 |
Questions teachers ask
Can the timer go longer than an hour?
Yes. The minutes box goes up to 180 (3 hours). Times over an hour show as hours, minutes and seconds, such as 1:30:00.
How do I start a 50 minute timer?
This page is already set to 50:00. 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 50 minute timer turn yellow and red?
It turns yellow with 25:00 left and red with 10:00 left. You can turn colour changes off so the disc stays green.
What sounds does the 50 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.
