Telling time to the minute

Mathematics · Measurement · procedural

Measure and begin to record time in hours, minutes, and seconds

  • Use a sand timer or stopwatch to time an activity
  • Begin to understand that 1 minute = 60 seconds
  • Record a duration in simple terms (e.g. 'it took about 2 minutes')
