This week in maths, the children have been exploring how numbers are broken down into parts. We looked at a lot of pictures first and then the children used cubes, counters on plates and part-part-whole models to show the 'whole' number and 2 or 3 'parts' that make up that number.
For example, 5 is the whole and the parts are 4 and 1 or 3 and 2 or 5 and 0. This will help the children to learn their number bonds for numbers within 10 and then eventually their number bonds for numbers up to 20.
The children also began to understand that addition is commutative i.e. it can be done in any order, by discussing that the 'parts' of 5 can be 3 and 2 or 2 and 3. The whole will still be 5 each time.
