Pace a class period

Class periods often run about 45 minutes. A timer on the board keeps the lesson on plan, and during an exam the pie shows students how much time remains without anyone calling it out. At home, 45 minutes fits a long study session or deep work. Plan a break after it.

A 45-minute study session

  1. Pick one topic and gather everything you need before you start.
  2. Start the pie and work through practice questions.
  3. When about a third of the pie is left, switch to reviewing your mistakes.
  4. When the pie is empty, take a 10 to 15 minute break.

What fits in 45 minutes

In the classroom

  • A science lab
  • A practice test
  • A long project block

At home and at work

  • Assembling furniture
  • Roasting vegetables
  • A long study session with a break after

Try this

For a long block, set the timer for the work you can do, not the work you hope to do. Add time at the end if you need it.

45 minute timer questions

How do I start a 45 minute timer?

Press Start. This page opens with the pie set to 45 minutes. When time is up, the timer plays three soft tones and counts the time over.

Can I show it to a class or change the length?

Yes. For a class, turn on Projector colors and press Full screen. To change the length, tap another length under the pie, or drag around the pie to set any time from 1 to 180 minutes.

How should I split a 45-minute class?

A common plan is about 5 minutes to open, 30 to 35 minutes of main work, and 5 minutes to wrap up. Run a timer for each part, or one 45 minute timer for the whole period.

How long should a study session be?

Long enough to get into the material, and short enough to keep your focus. A 45-minute block followed by a 10 to 15 minute break is one common pattern. Shorten it if your attention fades sooner.
