Main Focus: Mentally doubling a number
 Double numbers to 20
 Double multiples of 10 up to 100 e.g. double 40 is 80
 Know key doubles e.g. Double 15 is 30, double 25 is 50
This is a key area of maths that we would like you to focus on this half
term with your child. Start with doubling small numbers and work up.
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.

Numbers that are
tricky to work out!
Partition the number into tens and

30 and 4), double those separately
(60 and 8) and then add the two
answers together.
