Hours and Half Hours
Read o'clock and half past on both kinds of clocks.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 57
- A clock has two hands. The short one is the hour hand. The long one is the minute hand.
- When the minute hand points straight up to 12, it's o'clock. The hour hand points to 3, so it's 3 o'clock. A digital clock writes 3:00.
- Half an hour later, the minute hand points down to 6. It's half past 3, or 3:30. See how the hour hand moved halfway to the 4?
- Your turn! Turn the hands to show 7:00.
- Now try 7:30. The minute hand goes to 6!
Georgia's K-12 Mathematics Standards:
- 2.MDR.6.1 — Tell and write time from analog and digital clocks to the nearest five minutes, and estimate and measure elapsed time using a timeline, to the hour or half hour on the hour or half hour.
