How the 55 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 55:00 down to 27:30 | More than half the time left |
| Yellow | From 27:30 down to 11:00 | Less than half left |
| Red | The last 11 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).
