Throughout the school there is a focus on learning maths using practical objects, then pictorial recording before teaching children symbolic recording. This will prepare children for the demands of the National Curriculum for Mathematics. We encourage children to explain how they arrived at a specific answer, and compare different ways of calculating to decide which is the most effective. This ‘mathematical reasoning’ is a significant part of the maths curriculum and enables us to find out whether children really understand what they are doing and why.
