- If you double the multiples of 2 and double again you get the multiples of 8

### Common misconception

Pupils may misunderstand the contexts or language within worded problems and therefore not understand the calculation required to solve.

Model clearly how to identify key phrases and words which will identify the operation and equation required for word problems. Pupils may benefit from representing what is known and what is unknown such as by drawing a bar model.
