As children progress through KS2 they will learn more about multiples in Maths. As well as being familiar with the multiples of the numbers 2, 5, 10, 50 and 100 , in Year Four children will be exposed to the multiples of other numbers corresponding to their increasing knowledge of times tables. They will also come to learn how to work out multiples using division as well as multiplication.

A multiple is a number resulting from the multiplication of two other numbers. You can find which numbers a multiple is of by using division. If a number can be divided by another number with no remainder then it is a multiple of that number. For example, 25 and 30 are multiples of 5 because they both can be divided by 5. Did you know that the number 0 is a multiple of everything?
