## Lesson details

### Key learning points

1. Look at the numbers in the problem to decide which strategy is most effective and explain why.
2. Use partitioning strategies if the numbers are related by times tables.
3. Use short multiplication or division if the numbers are not related by times tables.

### Common misconception

Pupils may not be able to identify the key words leading to the operation.

Highlight the keyword and read back the question highlighting the context of the word problem. Words such as 'of' will need exemplifying.

### Keywords

• Multiplication - The basic idea of multiplication is repeated addition.

• Division - Division is splitting into equal parts or groups. It is the result of "fair sharing".

• Inverse - Inverse means the opposite in effect. The reverse of.

Ensuring pupils understand the inverse of each operation is key to this lesson. Encourage children to also use the inverse to check their answers.
