It’s a good idea to try and bring the maths your child is focusing on ‘to life’ in the stories you read together. Most books present opportunities to do something, even if it’s just getting your child to look at the sequence of page numbers and use them to find a page.
Here are some you many already have that are great for particular areas of Maths:
Number pattern & order: Bertie and the Bear by Pamela Allen (K & upwards)
Making comparisons: Counting on Frank by Rod Clement (K & upwards)
Subitizing: The Grouchy Ladybird by Eric Carle (K & upwards)
Partitioning : One Is a Snail, Ten Is a Crab by Sayre & Cecil (K & upwards)
Counting large numbers: Out for the Count by Cave & Riddell (K & upwards)
