Multiples are a major part of KS2 Maths. In Year Three children will be taught to recognise and work out multiples for the numbers 2, 5, 10, 50 and 100. This goes hand in hand with their previous knowledge of times tables and multiplication.

A multiple of a number is the result of multiplication with some other whole number, for example 3 x 5 = 15 so 15 is a multiple of 3 and 5. Knowing the times tables for different numbers will help you to work out multiples. Each of the numbers in a times table is a multiple of the first number, for example 5, 10, 15, 20, 25 and 30 are all multiples of 5. The same rule applies in all of the times tables.

How much have you remembered from your school classes about multiples? Take this quiz for 7-8 year olds all about multiples and multiplication and find out!

1.

Which is the next multiple of 5 after 120?

115

121

130

Just add 5!

2.

Which is a multiple of 50 and 100?

50

200

250

750

As 100 is a multiple of 50, all multiples of 100 are also multiples of 50

3.

Which of these is a multiple of 50?

75

220

250

A multiple of 50 always ends in 00 or 50

4.

What is the next multiple of 2 after 198?

199

200

208

198 + 2 = 200

5.

Which is the smallest multiple of 100?

50

100

200

300

Every number is a multiple of itself as it is itself multiplied by 1

6.

A multiple of 2 is always?

An odd number

A multiple of 5

An even number

A number ending in 2

A multiple of 2 ends in 0, 2, 4, 6 or 8 and is therefore an even number

7.

What does a multiple of 100 always end in?

00

2

5

11

Similarly, multiples of 10 (20, 30, 40 etc.) always end in 0

0

0 or 00

0 or 5

Think of the numbers in the 5 times table: 5, 10, 15, 20, 25, 30 etc

9.

Which of these is a multiple of 2 and 5?

2

5

10

15

2 x 5 = 10.

20, 30 and all other multiples of 10 are also multiples of 2 and 5

20, 30 and all other multiples of 10 are also multiples of 2 and 5

10.

Which is the multiple of 100 before 1,000?

100

500
