## Lesson details

### Key learning points

1. Properties of number allow us to talk about numbers and to sort and classify them

### Common misconception

Pupils who are insecure with their times tables may not be efficient at finding factors and multiples.

Provide children with a multiplication grid to support them in identifying factors and multiples. When finding a multiple, ask: 'Is it in the x times table?' When finding a factor, ask: 'Which times tables is this number in?'

### Keywords

• Factor - Factors are whole numbers which exactly divide another whole number.

• Multiple - A multiple is the result of multiplying a number by an integer (not by a fraction).

• Property - A property is a character or quality that something has.

• Classify - When you classify objects, you arrange the objects by some property.
