### Key learning points

- Multiples of ten can be represented with addition of tens.
- 10 + 10 + 10 is equal to three tens which is equal to 30
- An expression shows the number of groups being added.
- An equation includes the sum or total shown using =

### Common misconception

Children may think that each group of ten is worth more than the last when we count up in tens.

Ensure children understand that we count all as we go along to find how many things are in a group, the last number we say tells us how many there are.
