## Lesson details

### Key learning points

1. There are three times as many threes as nines.
2. We can say that triple three is equal to nine.
3. Triple means 'three times'.

### Common misconception

Pupils may find it difficult to solve problems or misunderstand questions.

Model clearly how to identify key phrases and words which will identify the operation and equation required for word problems. This could involve drawing bar models or other representations.

### Keywords

• Triple - To triple means to become three times as many or to multiply by three.

By this point fluency in 3 and 9 times tables will support children in solving these problems. Continue to chorally rehearse the 3 and 9 times tables.
