Classroom Timer
A clean, distraction-free visual countdown timer for classroom activities. Set any duration, display it full screen so students can always see the time remaining, and get an audio chime when time is up. Perfect for tests, group activities, transitions, and more. You can also use the Days Until Calculator to count down to important school dates like holidays or field trips.

Classroom Timer Tips
Use it for transitions
Setting a 2- or 3-minute timer for transitions (packing up, moving to a new activity) reduces downtime and helps students self-regulate. They learn to beat the clock rather than wait for a teacher prompt.
Set expectations with the label
The activity label field doubles as a quick visible instruction. Labeling a 10-minute timer "Independent Reading" or "Solve Problems 1–5" helps students stay on task without repeated verbal reminders.
Project in full screen during tests
Use full-screen mode during quizzes or timed assessments. The large font and high-contrast color scheme is readable from the back of most classrooms without requiring students to leave their seats.
Pair with discussion protocols
For structured activities like think-pair-share or Socratic seminars, set equal time segments for each phase. Reset and restart between phases so students know exactly how much time remains for each step.
