Year 1 Handbook

Time: o'clock and half past

Read the hour and half-hour positions on an analogue clock.

What you are learning

Read the hour and half-hour positions on an analogue clock.

Key idea

The short hand shows the hour. The long hand points to 12 at o'clock and to 6 at half past.

At o'clock, the long hand points to 12.

Worked example

Read 3 o'clock

3 o'clock

  1. Find the long hand. It points to 12, so the time is o'clock.
  2. Find the short hand. It points to 3.
  3. Say the time as 3 o'clock.

The clock shows 3 o'clock.

Another way

Use the clock position

The long hand at 6 means half past. Read the short hand as the hour it has passed.

Why this works

The clock face is divided into 12 hour positions. The long hand makes one complete turn in an hour, while the short hand moves between hour numbers.

Common mistake

Remember

Short hand: hour. Long hand at 12: o'clock. Long hand at 6: half past.
