This is a 21 page colouring by Maths book based entirely on KS1 Maths objectives. It covers lots of different number and calculation objectives. Children in Year 2 and above enjoy colouring in each picture, using their Maths knowledge.
It comes with a contents page which outlines which objective is covered so you can just print the pages which cover the current objectives.
Some teacher in my school love setting it as homework as a great way to reinforce recent learning!
