This free online classroom timer is built for teachers using a projector, smartboard, or front-of-room display. Add the activity and what students should do when time ends, choose an exact duration, then switch to full screen. The running view keeps the instructions, countdown, and controls together without an account or an ad beside the clock. Calm Display replaces changing seconds with a stable whole-minute estimate when a fast countdown would add pressure.
A clear way to use it
- Name the activity in a few clear words, such as Silent reading, Quiz, or Pack up.
- Write one finish instruction so students know what happens when the timer ends.
- Choose the duration and select Silent or Gentle chime for a quieter room.
- Turn on Calm Display when whole-minute updates suit the group better than changing seconds.
- Open full screen, then press Space or Start when everyone is ready.
- Use the plus or minus controls to change the deadline without stopping the activity.
Adjust when needed
- Put the action first in the activity label: Read, Discuss, Write, Check, or Pack up.
- Use a silent finish for tests when the visible end instruction is enough.
- Keep full screen on while projecting so unrelated browser tabs and page content stay out of view.
- Copy the setup link when another teacher needs the same duration and instructions. The link includes the text you entered, so do not put student names or private information in it.
Useful questions
What timer length works for common classroom activities?
Try 1 to 3 minutes for an exit ticket or quick transition, 5 minutes for a warm-up or cleanup, 10 to 15 minutes for reading or partner work, and 20 to 30 minutes for independent practice or a quiz section. Adjust the time to the age group and task instead of treating any duration as universal.
Can I use this timer on a projector or smartboard?
Yes. Open the page in the browser connected to the classroom display, set the activity and finish instruction, then use full-screen mode. Test text size, contrast, sound, and the finish instruction from the back row before students arrive.
Can students at the back of the room read this timer?
Full-screen mode enlarges the activity, countdown, and finish instruction while removing the rest of the page. Check the display from the back row before class, because projector size, contrast, and room lighting vary.
What does Calm Display do?
Calm Display shows the remaining time as a whole-minute estimate instead of changing the seconds every moment. The underlying countdown remains exact, the progress ring continues to move, and the chosen alert still happens at zero.
Can I use the classroom timer for an exam?
Yes. Add the exam section as the activity, use a short final instruction such as Pencils down, and choose Silent if an alarm would be disruptive. Keep the official room clock and your institution's timing rules as the authority.
Does the shared setup include student data?
The link contains only the duration, display preference, sound setting, and the activity and finish text you chose. Avoid names or sensitive information. FocusHub does not add your local session history to the link.
