## Lesson details

### Key learning points

1. Multiples of 4 are all multiples of 2 but not all multiples of 2 are multiples of 4
2. Multiples of 4 are double the multiples of 2
3. Multiples of 2 are half the multiples of 4

### 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.

### Keywords

• Multiple - A multiple is the result of multiplying a number by another whole number.

• Double / doubling - To double means to become twice as many or to multiply by two.

• Halving - Halving means to divide into two equal parts.

By this point fluency in 4 times tables will support children in solving these problems. Continue to chorally rehearse the 4 times tables.
