end in.../first digit goes up,
last digit goes down

If you add the answer’s
digits together, they add 9
e.g. 9 x 5 = 45
(4 + 5 = 9)

If you know your 2x tables,
then you can work out 4x
any number. X by 2, then
double it.
(always a tricky one!)
Answer first: 56 = 7 x 8. So it’s 5, 6, 7, 8.
Easy!

There isn’t a truly pain-free answer because…
• Everyone learns in best in different ways
• Real fluency demands practise over
weeks and months
Drilling is the key!
Practise, practise, practise!

Whilst children learn about numbers and maths at
school, there are also lots of ways that you can
support your child at home.
It doesn’t have to be by doing pages of sums or
text books – there are lots of fun activities and
games you can do or include in your everyday
routines!
Here are a few ideas to
help you…
