Classroom Timer Tips
Seven ways teachers use a timer on the board, and how to set each one up in a few seconds.
1. Calm transitions
Give a warning before a change ("two minutes left") and show it. A visual timer with the numbers hidden lets pupils see the time shrink without reading a clock. The Indiana Resource Center on Autism describes visual timers as a way to help some pupils on the autism spectrum see how much time is left before a transition (Hume, 2008, read 10 November 2026).
2. Clean-up in a set time
A 3 to 5 minute hourglass on the board turns tidying into a race against the sand. Flip starts it again from full.
3. Station rotations
On the interval timer, set Work to the time at each station, Rest to the move time and Rounds to the number of stations: 5 stations of 10 minutes with 1 minute to move is 55 minutes in total. The word WORK or REST is on the board, so nobody has to remember which colour means what.
4. Tests and timed writing
Put a 30 or 45 minute timer in full screen. Near the end the picture turns orange and then red with stripes, which is a quiet, visible "5 minutes left" for the room. If you need the computer for something else, the time left stays in the browser tab title.
5. Think time and pair talk
Short, fixed think time (a 1 minute timer) before hands go up gives slower thinkers a fair chance. For pair talk, 2 or 3 minutes is usually enough.
6. Quiet alarms
Pick Soft or Chime under Sound, press Test before the lesson, and turn the volume down. With None, the board flashes four times and shows "Time is up" without a sound, which suits exams.
7. Count down to something exciting
Make a countdown to a trip, a show or the holidays with Days until, or use the summer and Christmas countdowns. Save it and it is there the next day on the same computer.

Questions and answers
What is the best timer for young children?
A visual one: the classroom timer's shrinking disc, the visual timer or the hourglass, with the numbers hidden if they cannot read a clock yet.
How do I stop the timer from being too loud?
Choose Soft or Chime under Sound and lower the volume, or choose None for a silent visual finish.
Can I run a timer for every station?
Use one interval timer for the whole room: every pupil moves on the same beep, and the board shows which part you are in.
