Classroom timer
A big visual countdown that students can read from the back of the room. The ring shrinks and changes from green to yellow to red as time runs out.
Using it in class
- Put it on the projector or smartboard and press Full screen.
- Tap a preset for quick activities, or type a custom length.
- Press Space to start and pause without reaching for the mouse.
- The Paper theme (black on white) shows up best on washed-out projectors.
Good for timed tests, group work, transitions, reading time and clean-up. It's free, with no ads inside the timer and no sign-up, and it works on Chromebooks.
