In KS2 Maths children will learn more about number sequences. This begins in Year Three with children recognising simple patterns, for example sequences increasing by 2, 3, 10 or 100 each time. They should also be able to recognise odd and even sequences of numbers.

Understanding number sequences is all about recognising patterns in the order of numbers. We can all see that in the order 1, 2, 3, 4, 5 the numbers are increasing by 1 each time. Therefore we have found the pattern. We know that the numbers are increasing by 1 so we know that the following number will be a 6. We just need to add 1 to 5.

How good are you at recognising patterns in number sequences? Can you find the rules for these number sequences in this quiz for 7-8 year olds?

1.

What is the next number of the sequence? 20, 120, 220, 320

300

350

400

420

The numbers are increasing by 100

2.

If you add two odd numbers together the answer is always what?

An odd number

An even number

A number ending in 5

A number ending in 2

Even + even = even

Even + odd = odd

Odd + even = odd

Odd + odd = even

Even + odd = odd

Odd + even = odd

Odd + odd = even

3.

How do we know a number is even?

It ends in 0, 2, 4, 6 or 8

It ends in 1, 3, 5, 7 or 9

It ends in 5

It ends in 9

All the even numbers can be divided by 2 and give a whole number

4.

How do we know a number is odd?

It ends in 6

It ends in 0, 2, 4, 6 or 8

It ends in 1, 3, 5, 7 or 9

It ends in 2 or 4

If odd numbers are divided by 2 there will be a remainder or fraction left over

5.

If you add two even numbers together the answer is always what?

An odd number

An even number

A number ending in 2

A number ending in 0

2 even numbers always make an even number but an even with an odd will make an odd number

6.

Which sequence is odd?

4, 6, 8, 10, 12

30, 32, 34, 36, 38

17, 21, 25, 29, 33

12, 20, 28, 36, 44

All the numbers end in 1, 3, 5, 7 or 9 so it must be odd

7.

What are the next two numbers of the sequence? 3, 6, 9, 12

15, 18

13, 14

15, 17

15, 20

The numbers are increasing in 3s

8.

Can you find the rule of this sequence? 3, 13, 23, 33

The numbers increase in 2s

The numbers increase in 3s

The numbers increase in 5s

The numbers increase in 10s

Each number (except the first) is 10 higher than the one before it

9.

Which is the next even number after 148?

158

150

160

152

148 + 2 = 150

10.

Can you find the rule of this sequence? 5, 10, 15, 20, 25, 30

The numbers increase in 2s

The numbers increase in 3s

The numbers increase in 5s

The numbers increase in 10s

This sequence is the 5 times table
