Main Focus: Mentally halving and quartering a number.
 Halving even numbers to 20
 Halving multiples of 10 up to 100 e.g. half of 100 is 50, half of 60 is
30.
 Find a quarter of a number by halving and halving again e.g. to find
a quarter of 80, halve it to get to 40 then halve again to get to20.
This is a key area of maths that we would like you to focus on this half
term with your child. Start with halving small numbers and work up. Then
move onto quartering. If they are fluent at these skills can they now
double numbers?
Remember little and often is key to success! We have included a few
ideas of how you can help your child learn these skills, but feel free to
come up with your own.
Please also feel free to bring in photos, pictures or work that your child
has completed at home to go on our super home learning maths board.
The children are able to earn stars for their class each time they do this to
win prizes each half term.
If you need any support your child’s class teacher will be happy to help.
Everyday activities
Spot numbers as you walk or
drive. Can they be halved or
quartered?
Walking along the street
looking at house numbers. Can
you halve them? Can you halve
the numbers on both sides of
the street? Why not?
Online
Remember each child has access to Education
City where there are lots of games to play to
help them learn.

Colour in a number can they find the double?
What do you notice when you
halve all the multiples of 10?
Can you quarter these? How
about halving numbers that
end in 8? Can you quarter
these?
A cake recipe makes 24 cakes, but you only need
12 – can you halve the recipe to
make the right amount? What
would you do to make 6 cakes?
Playing
Numbers that are
tricky to work out!
Use your child’s favourite toys to engage them in
their learning. Teach the teddy!
How many are there? I remove half, how many
are there now? If I had 7 could I halve them?
Why not? What do you notice about the
numbers that we can half? Are they odd or even
numbers?
Build towers – can they build one
that is half the size? How many
bricks did they use? Can they make
one that is a quarter of the size?
Partition the number into tens
and ones (in this example it
would be 50 and 6), halve those
separately (25 and 3) and then
add the two answers together.
