grade 1 Clock Reading

A clock has a short hand and a long hand, and reading them together tells you the time. The short hand points to the hour, and the long hand points to the minutes. When the long hand points to 12, it is an o'clock time like 3:00; when it points to 6, it is half past, like 3:30. Pick a time with the sliders and both hands move to show it.

💡 How to read a clock
①The number the short (orange) hand points to is the hour
②When the long (blue) hand points to 12, it is o'clock
③When the long hand points to 6, it is half past
④At half past, the short hand sits between two numbers
⑤The number for the current hour is colored orange on the clock face

Times in your day

📅 Times in a day
①At 8 in the morning, you go to school
②12 o'clock is lunchtime
③At 3:30, it's snack time
④At 6, you eat dinner
⑤At 9, it's time for bed

Wrap-up

Short hand
short hand → the hour
Read the number the short hand points to
Long hand
long hand at 12 → o'clock / at 6 → half past
Read the minutes from where the long hand points
Telling time
short hand + long hand = the time
Example: short hand on 3, long hand on 12 → 3 o'clock
🎯 Remember
①The short hand shows the hour, and the long hand shows the minutes
②Long hand on 12 means o'clock; on 6 means half past
③The clock only goes up to 12, so the short hand goes around twice each day
④Every time comes once in the morning (a.m.) and once in the afternoon or evening (p.m.)

Examples and unit check

Example 1
The long hand points to 12 and the short hand points to 3. What time is it?
1
When the long hand points to 12, it is o'clock.
2
The short hand points to 3, so it is 3 o'clock.
▸ 3 o'clock
Read the hour from the short hand; if the long hand is on 12, it is o'clock.
Example 2
The short hand is between 9 and 10, and the long hand points to 6. What time is it?
1
When the long hand points to 6, it is half past.
2
The short hand has just passed 9, so it is half past 9.
▸ 9:30 (half past 9)
At half past, the short hand sits about halfway between two numbers.
Unit check
The long hand points to 12 and the short hand points to 7. What time is it?
①6 o'clock
②7 o'clock
③7:30
④12 o'clock
▸ ② 7 o'clock
1
The long hand is on 12, so it is o'clock.
2
The short hand is on 7, so it is 7 o'clock.
