Dear parents/carers,
At St Brendan’s RC Primary School, we believe that knowing times and divide tables is a key
Maths skill. It offers a foundation for learning other aspects of Maths. Regular practise of times
tables is essential in ensuring that they are embedded in the children’s long term memory.
This is a Year 5 booklet, which focusses on the factors, multiples, prime numbers, multiplying and
dividing using known facts and squared and cubed numbers. We request that the children
practise their times tables at home on a regular basis to support them with these areas of Maths.
The children need to be able to answer all mental multiplication and division questions accurately
and timely.
Tips for helping your child to learn their times tables:
~Regular practise (at least 3 times a week)
~Demonstrate
~Chant / sing songs
~Stick up a chart
~Play games

Dear student mathematician,
You are working on the Year 5 booklet, which focuses on multiples, factors, prime
numbers, multiplying and dividing using known facts, square and cube numbers. It is very
important that you practise these as often as you can to improve your speed and accuracy.
How quickly can you answer 40 questions?
Tips to help you learn your key facts:
~ Practise chanting your times tables
~Make a rhyme
~Ask someone to test you in a random order.
Good luck!

Top Tips:
A multiple is a number which can be divided by another
number without a remainder. Multiples appear in the number’s
multiplication table. You can calculate them by counting on by
that number.

Factors
The factors of 24 are: 1, 24, 2, 12, 3, 8, 4 & 6.
The factors of 32 are: 1, 32, 2, 16, 4 & 8.
The factors of 108 are: 1, 2, 3, 4, 6, 9, 12, 18, 36, 27, 54 & 108
Top Tip:
A factor is a number that divides exactly into a larger number.
To find the factors of a number, you can set it out like this:
Factors of 18:
18
1 x 18, 2 x 9, 3 x 6, therefore, the factors of 18 are 1, 2, 3, 6, 9 & 18.

Prime Numbers
Top Tips:
The numbers shown in yellow above are all prime numbers.
Prime numbers can only be divided by 1 and itself. 1 is not a
prime number. 2 is the only even prime number. There are no
prime numbers ending in 5, except 5. To test if a number is a
prime number, divide it by 2, 3, 5, 7, 9 or 11.

Multiplying and dividing using known facts
1 x 80 = 80
400 ÷ 8 = 50
90 x 80 = 7200
2 x 80 = 160
480 ÷ 8 = 60
10 x 80 = 800
3 x 80 = 240
560 ÷ 8 = 70 8800 ÷ 10 = 880
4 x 80 = 320
640 ÷ 8 = 80
960 ÷ 8 = 120
Top Tip:
Practise your times tables at home because if you know your times tables and corresponding
division facts, this will help you mentally calculate multiplication and division facts that are
ten, hundred, thousand etc. times bigger.
E.g. if you know that 7 x 6 = 42, then you should know the answer to 70 x 6, as it is 10
times bigger. Therefore, 70 x 6 = 420.
If you know that 8 x 9 = 72, then you should know the answer to 80 x 90, as it is 100 times
bigger. Therefore, 80 x 90 = 7200.
