How to Use This Classroom Timer
- Pick a duration. Choose a preset (1–30 minutes) or type a custom number of minutes.
- Press Start. The big display counts down and the progress bar shrinks so students can see time passing at a glance.
- Go fullscreen when projecting. Click the fullscreen button for a clean, distraction-free display on your classroom screen or interactive whiteboard.
- Listen for the alarm. When time runs out, a gentle chime sounds and the display flashes.
Classroom Timer Tips for Teachers
- Transitions: a 2–3 minute timer makes cleanup and switching activities dramatically smoother.
- Young learners: the shrinking progress bar works as a visual timer — perfect for kids who can’t read a clock yet.
- Tests and quizzes: project a 15 or 30 minute timer so everyone paces themselves.
- Group work: set 10 minutes, then use the alarm as the signal to rotate or share out.
- Brain breaks: a visible 5-minute break timer helps students actually relax — and actually come back.
