If (and only if) your Year 2 are secure in their understanding of time in hours, my next step will be to introduce the concept of half past.
Going back to my horizontal number line, I will position the hand half way “past” the 2 and 3, as below:
A number line pointing between two and three to represent half past two
I will explain that because the hour hand is halfway between the 2 and 3 (or half way past the 2) we say it is half past 2. This means it is half way past two hours. Repeat for various numbers.
Then, once again, rearrange your post its into a clock face to model a clock and get children to show various times using their hour hand only clocks. Then ask what time it will be half an hour later and show how it will be 3 o’clock.
Then half past 3, and so on. Repeat this using your hour hand only example and get the children to do the same.
Once this is secure, there is lots of Maths you can do using your circular number line to work out what time it will be:
Finally, at this stage, Year 1 and 2 children are ready for the familiar worksheet with clock faces showing o’clock and half past. Although you will of course have removed the minute hands from these!
Tell the children that when they see a clock with two hands, to ignore the other hand for now and that they will still be able to tell if it is o’clock or half past or nearly o’clock or half past.
Throughout the day when you are teaching telling the time draw attention to the class clock and say things like, “we go to PE at 2:30 and look, the hand is almost half way between the 2 and the 3, that must mean it is almost 2:30, so in a few minutes it will be time for PE.”
This is so much easier than having to remember about a 6 meaning half past.
