Teacher Resources
Teaching Notes

Emphasize connecting time units to real-world activity durations. Discuss why certain activities take minutes versus hours or seconds.

Vocabulary
Second: A very short unit of time.
Minute: A medium unit of time.
Hour: A long unit of time.
Common Mistakes
  • Confusing seconds/minutes for longer durations like hours.
  • Choosing a unit that is not reasonable for the activity's actual duration.
  • Guessing instead of visualizing or estimating the activity's length.
Differentiation
SupportUse visual schedules and discuss personal daily routines.
ChallengeEstimate durations of complex activities; introduce conversions.
Discussion Questions
  • What activities do you do that take about one minute?
  • When would it make sense to measure an activity in seconds?
  • Why is it important to know how long different activities take?
  • Can you describe an activity that would take several hours to complete?
Extension Activities
  • Time activities with a stopwatch.
  • Compare durations.
  • Plan a day using time units.
Parent Tip

Ask your child if an activity takes seconds, minutes, or hours.
