Maths
At Mengham Junior School, we are dedicated to developing confident mathematicians whose mathematical fluency allows them to solve ever more challenging problems. We use discussion to promote reasoning and explore new concepts, building them up layer by layer.
Across all year groups, we are using a mastery approach to teaching and learning mathematics. This is supported by a primary maths programme called “Inspire Maths”. We use it to build firm foundations and a deep understanding of mathematical concepts through a concretepictorialabstract approach. The concrete step can be thought of as the “doing” stage and involves physically manipulating objects to solve a maths problem. The pictorial stage or “seeing” stage involves using images to represent objects. The final step in this approach, abstract, is known as the “symbolic” stage and involves using only numbers and symbols to solve maths problems.
Our pupils get a varied and challenging diet of Maths problems. This helps them become successful at solving both routine and nonroutine problems. The focus on deep understanding and solving problems makes maths lessons at Mengham an enjoyable and exciting place to be.
