 You can check if 2 x 3 = 6 is correct by dividing 6 by 2. It should give the answer 3.

# Year 2 Calculation - Division

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 using related division facts to perform written and mental calculations.

Year 2 children should begin to understand the relationship (or facts) between multiplication and division, and learn how they can use that relationship to check their answers. For example, if they calculate that 3 x 4 = 12, than they could check by calculating that 12 shared into 4 equal groups would give 3 in each group. Knowing and using the division facts will help with this.

Question 1
What is the opposite, or inverse of multiplication?
Subtraction
Multiplication
Division
Division and multiplication are the inverse of each other, as are addition and subtraction
Question 2
If 10 groups of 3 is 30...
then 30 multiplied by 30 will give 10
then 30 divided by 30 will give 3
then 30 multiplied by 3 will give 10
then 30 divided into groups of 3 will give 10 groups
A division 'cancels out' the multiplication as it is the opposite
Question 3
Seven groups of 2 makes 14 so 14 divided into groups of 2 would make...
28 groups
14 groups
2 groups
7 groups
If 7 x 2 = 14, then 14 ÷ 2 = 7 or 14 ÷ 7 = 2
Question 4
What could you do to check this calculation is correct:
9 x 5 = 45
Multiply 45 by 9
Divide 45 by either 9 or 5
Multiply 45 by 5
Find the total of all 3 numbers
The calculation is correct, but checking it with either division would prove it
Question 5
Which division calculation could you use to check this is correct:
5 x 6 = 30
6 ÷ 30 = 5
6 ÷ 5 = 30
30 ÷ 5 = 5
30 ÷ 5 = 6
In the division fact, the largest number always comes first
Question 6
Which division calculation could you use to check this is correct:
10 x 5 = 50
50 ÷ 50 = 10
50 ÷ 5 = 10
10 ÷ 5 = 50
10 ÷ 50 = 5
You could also use 50 ÷ 10 = 5
Question 7
Which number is missing?
90 ÷ ? = 10
19
90
9
109
9 x 10 = 90 so 90 ÷ 9 = 10
Question 8
Which two division facts can be found from knowing that 8 x 5 = 40?
5 ÷ 5 = 8 and 8 ÷ 8 = 5
40 ÷ 5 = 8 and 40 ÷ 8 = 5
40 ÷ 40 = 8 and 5 ÷ 5 = 40
8 ÷ 5 = 40 and 5 ÷ 8 = 40
The largest number comes first, followed by either of the smaller numbers to give the other as the answer
Question 9
Which 'family' of facts is correct?
2 x 3 = 5
6 x 2 = 3
6 ÷ 5 = 3
2 ÷ 3 = 6
4 x 5 = 20
5 x 4 = 20
20 ÷ 4 = 5
20 ÷ 5 = 4
2 x 8 = 14
8 x 2 = 14
18 ÷ 2 = 8
18 ÷ 8 = 2
4 x 9 = 50
9 x 4 = 50
55 ÷ 4 = 9
55 ÷ 9 = 4
If the multiplication facts are correct, the division facts should use the same numbers
Question 10
Which number is missing?
? ÷ 5 = 7
35
57
75
30
5 x 7 = 35 so 35 ÷ 5 = 7
