Factors are whole numbers which exactly divide another whole number.

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

A property is a character or quality that something has.

When you classify objects, you arrange the objects by some property.

Use knowledge of properties of number to solve problems

Maths

 In this unit pupils will explain how to identify a multiple or common multiple to solve problems in a range of contexts. In the future unit pupils will explain why the product stays the same when one factor is doubled and the other is halved and use knowledge of equivalence when scaling factors to solve problems.

In the prior unit pupils explained reasons for changing 2-factor multiplication calculations to 3-factor multiplications and explained what a factor is and how to use arrays and multiplication/division facts to find them. They identified prime numbers and composite numbers. In this unit pupils will explain how to identify a multiple or common multiple to solve problems in a range of contexts.
