Classroom Timer for Teachers
This large, clear classroom timer is designed for teachers who need to display a countdown to their students. The circular progress ring makes it easy to see at a glance how much time is left — great for tests, group activities, transitions, and timed writing tasks.
How Teachers Use This Timer
Set the number of minutes and seconds, press Start, and press F or the fullscreen button to fill your projector or TV screen. The progress ring shrinks as time passes, giving students a visual sense of urgency without having to read the numbers. Use it for independent work periods, timed assessments, group activities, brain breaks, and classroom transitions.
Why Classroom Timers Work
Research on classroom management consistently shows that visible timers reduce transition time and increase on-task behavior. Students who can see time passing stay focused longer and are less likely to ask "how much time is left?" — giving you more time to teach.
