CGP offer a range of educational books which link directly to the national curriculum in a range of subjects. They are ideal for your child to work through at home to consolidate learning and also to provide catch-up support.
The link to the CGP website can be accessed here https://www.cgpbooks.co.uk/primary-books/ks2/year-4-(ages-8-9)
There are targeted question books for Spelling, Punctuation and Grammar, Maths and Reading, which I have linked separately.
