Math Mastery

Maths Mastery

Intent

At Otley and Witnesham Primary Schools, our ambition is for every child to develop a deep, lasting and adaptable understanding of mathematics. We believe every child can succeed in mathematics when given the right opportunities and support. We want every child to leave our school with a love of maths and the skills to succeed well. We follow a Maths Mastery approach, which focuses on building deep, secure and long-lasting understanding of mathematical concepts. 

We teach using the Five Big Ideas from the National Centre for Excellence in the Teaching of Mathematics (NCETM):

• Foster Conceptual Understanding: We aim to move beyond rote learning so pupils understand why mathematical structures and procedures work, using small, incremental steps.

• Develop Fluency: Ensure rapid, accurate recall of core arithmetic facts alongside a deep understanding of mathematical structures, enabling cognitive load to be freed up for complex reasoning.

• Build Mathematical Language: Empower pupils to reason, justify, and articulate their thinking using precise mathematical vocabulary and full sentences.

• Encourage Problem Solving: Build resilient learners who can break down routine and non-routine problems into manageable steps and apply their learning to science, technology, and real-world financial contexts.

We keep class cohorts together through the same curriculum content, ensuring no child is left behind while offering rich, depth-of-learning challenges rather than premature acceleration to new content.

Class structures:

Taught separately: Reception, Year 1 and Year 2

Taught in mixed-aged classes: Years 3 & 4, and Years 5 & 6

Implementation

We implement our curriculum through the NCETM Teaching for Mastery approach, supported by structured high-quality schemes including White Rose Maths, the NCETM Curriculum Prioritisation materials, Primary Mastery Professional Development materials and Oak Academy.

What this looks like at Otley and Witnesham:

• Coherence & Small Steps: Lessons break down complex concepts into small, progressive learning steps. Concepts are built sequentially, allowing all children to master foundational concepts before moving on.

• The Concrete-Pictorial-Abstract (CPA) Approach: Pupils use physical manipulatives (e.g., base ten, tens frames, counters) and visual representations (e.g., bar models, part-whole models) to anchor abstract mathematical concepts.

• Mathematical Language & Oracy: Teachers model precise mathematical terminology and encourage "maths talk." Children use stem sentences to clarify their reasoning, build arguments and embed mathematical structures.

• Varied Practice & Representation: Children are exposed to standard, non-standard, and variation-focused exercises. This challenges their perception of concepts and prevents procedural rote-learning.

• Number Sense & Fluency Focus: Daily dedicated practice, including the NCETM Mastering Number programme in EYFS and Key Stage 1. This ensures automaticity in key number facts. Interactive platforms like Times Tables Rock Stars support fluency in Key Stage 2, preparing children for the Multiplication Tables Check (MTC) and future mathematics.

• Targeted Support & Immediate Intervention: Assessment is continuous. Teachers use precise questioning and same-day or timely interventions to address misconceptions quickly, ensuring all pupils remain ready to move forward together.

Impact

The impact of our mastery approach is evident in pupils' attitudes, confidence and attainment across both schools:

• Confident, Fluent Mathematicians: Children exhibit quick and accurate recall of fundamental facts and concepts, showing flexibility when choosing efficient calculation strategies.

• Oracy: Pupils speak and write like mathematicians. They can explain how they arrived at an answer, spot patterns, make conjectures and justify their mathematical thinking using subject-specific language.

• Resilient Problem Solvers: Children tackle unfamiliar or multi-step problems with confidence and perseverance, drawing on concrete and pictorial strategies to expose underlying mathematical structures.

• Strong Outcomes: Pupil progress is monitored using formative classroom assessment and termly assessments. Children demonstrate strong progress relative to their starting points and leave Key Stage 2 fully prepared for the secondary curriculum.

• Positive Mindsets: Mathematics is seen as an inclusive, enjoyable subject where mistakes are viewed as valuable learning opportunities and every child believes they can succeed.
