How the 2 hour 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 2:00:00 down to 1:00:00 | More than half the time left |
| Yellow | From 1:00:00 down to 24:00 | Less than half left |
| Red | The last 24 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 2 hours into parts
For a long session, Station rotations can split the time into parts with a short break between them. Some ways to divide 2 hours of work, with 2 minute breaks added between parts:
| Parts | Each | Breaks | Total |
|---|---|---|---|
| 2 | 1 h | 2 min | 2:02:00 |
| 3 | 40 min | 4 min | 2:04:00 |
| 4 | 30 min | 6 min | 2:06:00 |
Questions teachers ask
Will a two-hour timer keep the projector awake?
While it runs, the page asks the browser for a screen wake lock where supported. Some devices and power settings can still override this, so check your projector's sleep setting for long sessions.
How do I start a 2 hour timer?
This page is already set to 2:00:00. 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 2 hour timer turn yellow and red?
It turns yellow with 1:00:00 left and red with 24:00 left. You can turn colour changes off so the disc stays green.
What sounds does the 2 hour 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.
