Clock Tab Add to Chrome

A classroom clock everyone can read from the back row

Put a large clock on the smart board so students can see how much time is left without asking. Switch to the timer for tests, group activities and breaks. There are no ads or sign-up, so nothing unexpected pops up in front of the class.

Ideas for lessons

  1. Tests: set the timer to the length of the test and press F for fullscreen.
  2. Group work: run a 5 or 10 minute timer and add a minute when groups need it.
  3. Breaks and transitions: show the clock so everyone knows when the lesson resumes.
  4. Reading time: use the stopwatch to time silent reading or fluency practice.
