- A square number can be represented as the product of two factors which are the same.
- When both factors have the same value, the product is called a square number.

### Common misconception

Pupils might think that a square number is simply any number or a number multiplied by 2

Remind children that a square number is the product of a number multiplied by itself (e.g., 4 × 4 = 16). Take time to use square arrays to demonstrate this.
