Colouring by Maths is a 21 page PDF based on the basic maths skills taught to children who are 5+ (Key Stage 1).
I have created each picture and the mathematics behind each one. At the bottom of each page are the colours needed and the maths that the child needs to know or work out to be able to colour the picture.
Each picture has a specific objective from the English National curriculum for Key Stage One.
