Half Past :30

Teaching half past

Prerequisites: reading o’clock times and knowing that the hour hand names the hour. See O’Clock for a recap.

Suggested sequence (10–15 min)

1. Halves first: Fold a paper circle in half, and cut an apple in half. “Half a turn round the clock is half past.”
2. Model: Start at an o’clock time, then turn the blue hand halfway round to the 6. Say, “It has gone half way round, so it’s half past.”
3. The Room Trick: Show the hour hand halfway between two numbers and ask “Whose room is it in?” Children name the smaller number.
4. Practice: Use Projector view with the “O’clock or half past” level and let pairs agree on an answer before you reveal.

Common misconceptions

• Reading the wrong hour. At 3:30, the red hand is nearer the 4 for some children, who say “half past four”. Use the Room Trick: it hasn’t crossed into room 4.
• “Half past 6”. Children see the blue hand on the 6 and say six. Ask: “Which hand tells the hour?”
• Expecting the hour hand to be on a number. At o’clock it is, but at half past it’s halfway between two numbers.

Questions to ask

• “Where is the blue hand? What does that tell us?”
• “Which two numbers is the red hand between?”
• “Whose room is it in?”
• “What would the digital clock show?” (:30)

Smartboard tip: start on Half past only, then switch to O’clock or half past to check children can tell the two apart.

Curriculum links

UK Year 1: tell the time to the hour and half past the hour. US CCSS 1.MD.3: tell and write time in hours and half-hours using analogue and digital clocks.

What your child is learning

Your child is learning to read half past times, such as half past 3. The long hand points straight down at 6, and the short hand sits between two numbers. They say the smaller number as the hour.

Why it can feel tricky

• The short hand is no longer pointing at a number, so children aren’t sure which hour to say.
• The word “half” links to maths: half a turn, half an hour, half an apple.

It’s completely normal for children to take a while to feel confident with this.

Easy ways to help at home

• Connect to halves: “Half an apple, half a pizza, half past the hour!”
• Say half-past times as they happen: “It’s half past seven — time to leave!”
• Ask “What’s the smaller number?” if your child is unsure of the hour.
• Let your child set an analogue clock to half past and tell you where the hands are.
• Keep sessions short and playful: 2 or 3 minutes is plenty.

Try this at breakfast: “It’s half past seven. What will the clock say in half an hour?” (8 o’clock!)
