 Lots of things come in groups of 10, like the green bottles in the song!

# Year 2 Calculation - Multiplication and Division By 10

This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with multiplication and division by 10.

Counting up and down in steps of 10 is an important and useful skill which helps with multiplying and dividing problems.. It is usually practised regularly, in order for the skill to be fluent, and children are also taught to recognise that multiples of ten are even and end with '0'. Once the 10 times table is familiar, children will learn how to use the multiplication facts to solve division questions. For example, if they know that 2 x 10 = 20, then they may also recognise that 20 ÷ 10 = 2 or 20 ÷ 2 = 10.

Question 1
What are the next two numbers in this sequence: 30, 40, 50, ?
51, 61
55, 60
51, 52
60, 70
The numbers are going up in steps of 10
Question 2
If one child has 10 toes, how may toes will 4 children have?
40
14
44
400
10 x 4 = 40
Question 3
I put 60 children into groups of 10. How many groups do I make?
10, because 60 ÷ 10 = 10
16, because 60 x 10 = 16
60, because 60 ÷ 1 = 60
6, because 60 ÷ 10 = 6
We also know that 6 x 10 = 60 and 10 x 6 = 60
Question 4
How many tens are there in 170?
100
7
17
71
Counting up in tens until you reach 170 is useful here
Question 5
Is 83 a multiple of 10?
Yes, because it has 8 tens
Yes, because it's bigger than 10
No, multiples of ten end with a '0'
No, it's not big enough
Multiples of ten have a '0' as a last digit
Question 6
I know that 5 x 10 = 50. What else do I know?
5 ÷ 10 = 50
50 x 10 = 50
50 ÷ 10 = 5
50 ÷ 5 = 500
If 5 groups of 10 makes 50, then 50 divided into groups of 10 will give 5 in each group
Question 7
Which is the odd fact out?
11 x 10 = 110
110 ÷ 11 = 10
11 x 11 = 111
110 ÷ 10 = 11
11 x 11 = 121 not 111!
Question 8
What is 8 x 10?
18
80
88
108
Multiplying by 10 makes the number 10 times larger
Question 9
What is 100 divided by 10?
10
20
100
1000
Dividing by ten means making groups of ten from the number until nothing is left
Question 10
Which is not true?
9 x 10 = 90
10 x 5 = 50
10 x 14 = 140
10 x 7 = 107
10 x 7 = 70
