### Key learning points

- When a whole is partitioned into parts, it can be represented using the addition symbol.
- The addition symbol shows that the parts combine to make the whole.
- We can describe the parts to help us understand how to represent them.

### Common misconception

Children may have difficulty understanding partitioning of the whole group where one part is zero.
