Introduction for teachers and parents
In this book there are single-page exercises covering most of the mathematics work that children will meet in Year 4.
On each page there are some examples/hints along with a set of questions for children to answer. There is space for answers to be written in the book.
Each exercise ends with a challenging question for the more able children.
At the end of each page, children are invited to answer a self-assessment question.
Using this book
The exercises in the Maths Practice Questions books are not intended to be used in the initial teaching of new mathematics topics.
However, they can be used as:
• Homework activities - to consolidate work done in class.
• End of topic class activities - to give children the opportunity to check their understanding of a particular topic.
• Assessment tasks - allowing teachers to establish whether or not children are secure in their understanding of a topic.

I’m confi dent I’m nearly thereI can estimate and use ‘inverse’ calculations to check answers.
Estimating and checkingF
Don’t forget that you can check a calculation by doing the ‘inverse’ calculation.
E.g. 120 – 30 = 90
check: 90 + 30 = 120
Try these calculations and check them. The fi rst one is done for you. Try these using your mental maths skills.

By the end of Year 4, children are expected to know the facts in this section. Parents can help by regularly asking questions to test their children’s ability to recall these facts.
A little and often is the best approach, and any available fi ve minute period can be used.
Appendix - Information for Parents
Number bonds to 100
Children need to know all the pairs of numbers that add up to 100. For example:
60 + 40 = 100 40 + 60 = 100
25 + 75 = 100 75 + 25 = 100
72 + 28 = 100 28 + 72 = 100
A
They also need to know the related subtraction facts.
100 – 60 = 40 100 – 40 = 60
100 – 75 = 25 100 – 25 = 75
100 – 28 = 72 100 – 72 = 28
Try to use a range of vocabulary.
E.g. What do you need to add to 58 to get 100?
What is 100 take away 12?
What is 40 less than 100?
How many more than 82 is 100?
What is the difference between 55 and 100?
You can also use ‘missing number’ questions:
46 + = 100 100 – = 49

By the end of Year 4 children should know the times tables up to 12 x 12.
Division facts
Children also need to know the division facts for each times table. For example:
Again, try to use a range of vocabulary when asking questions.
E.g. What is 6 multiplied by 4?
What is 7 times 6?
What is 36 divided by 6?

Top Tip
If your child knows the 2, 5 and 10 times tables and knows the square numbers, it may help them to answer times tables questions in steps like this:
7 x 7 = 49 so 8 x 7 = 49 + 7 =
8 x 8 = 64 so 8 x 9 = 64 + 8 =
5 x 8 = 40 so 6 x 8 = 40 + 8 =
56

48
8 x 7
8 x 9
6 x 8
Fractions and decimals
Children need to know these facts:
C
110
= 0.1 210
= 0.2 310
= 0.3 1010
= 1.0
1100
= 0.01 2100
= 0.02 3100
= 0.03 10100
= 0.1
12

= 0.25 34
= 0.75

Multiplying and dividing numbers by 10 and 100
Children need to know these facts for 1-digit and 2-digit numbers:
D
x 10 = 202 x 10 = 20020 x 10 = 25025
x 100 = 5005 x 100 = 400040 x 100 = 350035
÷ 10 = 660 ÷ 10 = 0.55
÷ 100 = 0.880 ÷ 100 = 0.066
You could ask any similar question and also try ‘missing number’ questions.
E.g. 60 ÷ = 6 etc.
