How to use the classroom timer
- Choose a preset, such as Group work · 15 min, or type the minutes and seconds and press Set the timer.
- Press Full screen so the countdown fills the projector or interactive whiteboard.
- Press Start. The button changes to Pause and then Resume if you need to stop for a question.
- Use +1 min to extend the activity and Reset to put the full time back.
When time is up, the clock shows “Time’s up!” and a short alarm plays. The countdown is calculated from a fixed end time, so it stays exact even if you switch to your slides in another tab. Where the browser supports it, the screen stays on while the timer runs.
Why a visual timer helps
Many students, especially younger ones, cannot yet judge how long “five more minutes” is. The ring around the digits empties as time passes, so children can see at a glance whether they are near the start or the end of an activity, without reading the numbers. A visible countdown also cuts down on “How long is left?” questions and makes transitions calmer, because the end of an activity is expected rather than sudden.
Preset lengths and ideas
| Preset | Length | Ideas |
|---|---|---|
| Clean-up | 2 min | Tidying desks, packing bags, lining up |
| Think-pair-share | 3 min | Thinking alone, then sharing with a partner |
| Brain break | 5 min | Movement, stretching, a quick game |
| Quiz | 10 min | Short quizzes, warm-up questions |
| Group work | 15 min | Projects, stations, discussions |
| Silent reading | 20 min | Independent reading, journaling |
| Test | 30 min | Tests and timed writing |
Tips for younger students
- Say the time out loud when you start, and point to the ring so students link the shrinking color to the time left.
- Give a warning with a minute or two to go, so nobody is surprised by the alarm.
- Keep it short. Several 5-minute blocks often work better than one long block for young children.
- Check the volume before class so the alarm is heard but does not startle anyone.
For other lengths, try the 5 minute timer or the 45 minute timer for a full class period. To structure study time with breaks, use the Pomodoro timer.
