Using Math to Tell Time

Reading Clocks

Clocks help us know when it's time to do things! You'll learn to read both digital and analog clocks.

Hours and Minutes

The short hand shows the hour, and the long hand shows the minutes. There are 60 minutes in one hour.

Counting Time

You can use addition and subtraction to figure out how much time has passed or how much time is left.

Why Telling Time Matters

Knowing how to tell time helps you get ready for school, know when to eat lunch, and plan your day!

Examples

  • If school starts at 9:00 and it's 8:30, how many minutes until school starts? (30 minutes)

  • If you watch TV from 4:00 to 4:45, how long did you watch? (45 minutes)
