45 Minute Timer

Forty-five minutes fits a full lesson, a test or a long practical. Keep the whole period on the board so students can pace themselves instead of asking how much time is left.

Timer style

How do you use the 45 minute timer?

  1. The timer is already set to 45 minutes. Press Start or the Space bar to begin, and Space again to pause.
  2. Press Present (or F) to show it full screen. Pick Pie, Bar or Digits, and choose an end sound.
  3. When time is up you'll hear the chime and see "Time's up!". Press Start again for another round, or +1 min if the class needs longer.

Ways to use a 45 minute timer in class

  • Full-period test: one clear countdown from the first question to pens down.
  • Science practical: set up, carry out and clear away before the chime.
  • Extended writing: plan, draft and check, with a glance at the board instead of the clock.

Questions teachers ask

Can I use the forty-five minute timer for a whole lesson?

Yes. Start it as the lesson begins and the class can see the time left all period. If you started late, press Reset and set a shorter time, or press +1 min to add time as you go.

Can students see how much time is left from the back?

Press Present (or F) for a full-screen countdown. Digits show the exact minutes left, and Bar or Pie shows at a glance how much of the period has gone.
