Children in Reception need to understand that 'half' is the same as sharing between 2 groups. Half is one of 2 equal parts. They need to understand that both groups need to be 'equal'; using the notion of fair and not fair will help with this. If one group has 3 cars and the second group has 4 cars then this is not fair as one group has more whereas if both groups have 3 cars then this is fair as they both have the same. They are equal.
- Using ladybirds (either using the template below or you can easily draw your own) and coins, raisins, chocolate buttons, cut out circles etc can you find half of 2, 4, 6, 8 and 10 by sharing the number of items onto each wing. Can you record your answers for example; Half of 2 = 1.
**When sharing we encourage the '1 to you, 1 to me, 1 to you, 1 to me' method or in this case '1 on this wing, 1 on that wing' etc.
Challenge yourself/Key Questions:
- Can you find half of a number to 20?
- Can all numbers be halved? What could you do with the left overs?
- What numbers can be shared between 3? 4?
- Showing 2 groups of objects (both with the same number of items) say to your child 'I have found half. True or false?' Repeat activity but this time 1 group should have more than the other. Can your child explain why it is or isn't half?
- Can all numbers be halved? Prove it/Show me. Can your child use objects and model sharing the items between to groups to show an example of a number that can't be halved?
- Pick a number for example 6 and say to your child 'half of 6 is 3. True or False?' Show me/Prove it. Can your child get 6 items and share it between 2 groups to find out? Repeat with different numbers sometimes giving them the correct answer and sometimes giving them an incorrect answer for e.g. 'half of 10 is 4'.
