Classroom Timer

About this classroom timer

This is a clean, distraction-free timer for classroom use — no flashing animations, no kids' theming, no popup ads to wait through. Set it for a class period, an activity, or a transition, project it onto the board, and it does its job. The default preset is 10 minutes, but the homepage lets you set any duration.

Common classroom timer uses

• Activity timing: "You have 10 minutes to finish question 3" works much better with a visible timer than a verbal reminder.
• Transition timing: 2–3 minutes for getting books out, lining up, or moving to the next station.
• Class period: a 45-minute timer can serve as a visible "we're 30 minutes in" reference.
• Test and quiz timing: show a clear, large countdown so students can pace themselves.
• Group rotations: a repeating timer with rounds works well for stations and small-group rotations.
• Brain breaks: 2–5 minute breaks between focused work blocks.

Tips for using a timer in the classroom

• Make it visible. Project it where every student can see — visible deadlines work better than verbal ones.
• Use it consistently. Students learn to pace themselves when the timer's predictable.
• Build in transition time. If activity time is 10 minutes and transition is 2 minutes, run the timer for 12 — and tell them what the breakdown is.
• Don't let the timer become punishment. Going over should sometimes be okay; otherwise students rush rather than think.

Useful classroom timer durations

• 2-minute timer — quick transitions, brain breaks.
• 5-minute timer — short writing prompts, exit tickets.
• 10-minute timer — short tasks, station rotations.
• 15-minute timer — independent reading, focused practice.
• 20-minute timer — small-group activities, paragraph writing.
• 45-minute timer — full class periods, tests.
• 1-hour timer — long blocks, exams.

Why a web timer beats apps for classrooms

• No installation — works on any computer, smart board, or projector with a browser.
• No school-IT permission issues — it's just a web page.
• No ads or notifications interrupting class.
• Bookmarkable; loads in any browser tab in under a second.
