"Don't let anyone look down on you because you are young. Be an example to all believers, in what you say, in the way you live, in your love, your faith and your purity."1 Timothy 4:12



At St. Mary’s C of E School, the teaching and learning of mathematics is a high priority as we recognise it as an essential skill for life. Our children are taught the 3 main areas of the National Curriculum Fluency, Reasoning and Problem Solving through a mastery curriculum. In order to meet raised national expectations within the National Curriculum we ensure that all of our children develop a deep and sustainable understanding of mathematical concepts through a maths curriculum which promotes a rich understanding of mathematical concepts taught in small steps in a systematic way through the use of Power Maths. We encourage our children to explore mathematical concepts using physical resources and pictures, enabling them to visualise and understand abstract concepts.  


We believe that every child can access their class learning objective, at varying degrees, and have full access to the curriculum.  Our teachers broaden and deepen children's understanding with questioning, whilst allowing children to explore new concepts or ones that need consolidating using resources to help develop their understanding.

We strive to offer a Maths curriculum which is consistent, sustainable and progressive through continuously looking at ways in which we can enhance the teaching and learning of mathematics within our school.

At St Mary’s C of E School, we have all been on a journey over the last three years in order to improve the teaching and learning of mathematics. Led by our Maths Leads, Mr Leigh Pritchard and Miss Kim Rundle.   we have worked to improve our children’s understanding of maths through development of the teaching for mastery approach within our school. This has involved training on each of the principles of teaching for Mastery, planning support and enhancing our classroom mathematical environments.

KIRFs (Key Instant Recall Facts) 

KIRFs are designed to support the development of children’s mental skills that underpin much of the mathematics work in school. They are particularly useful when calculating, be it adding, subtracting, multiplying or dividing.  

Each year group is allocated up to six skills to focus on throughout the year, in line with age related expectations. 

The expectation is that children practise these at home in small daily bursts so that they grow in confidence to recall their facts instantly. We will also refer to the KIRFs and practise them in school.

Please share your child’s progress towards learning their key skills via Seesaw. We will look forward to celebrating their learning! 

Each half term, children will complete a KIRF assessment with their teachers in class.
