The Westborough School


At Westbrough we follow the Mathematics Mastery approach through the ARC programme, which has three key principles: deep understanding, mathematical thinking and mathematical language, with problem solving at the heart of the curriculum. Instead of learning mathematical procedures by rote, we want pupils to build a deep conceptual understanding of concepts which will enable them to apply their learning in different situations. The habits of thinking mathematically are life-enriching as it is vital to be numerate to participate fully in society. Therefore, we ensure we make rich connections across mathematical ideas to develop those skills from EYFS to Year 6. 


The Mathematics Mastery programme has provided curriculum resources alongside professional development. Therefore, all teaching staff have now been fully trained in implementing the approach in their classrooms ensuring consistency throughout school. 


The Mathematics Mastery curriculum is cumulative - each school year begins with a focus on the concepts and skills that have the most connections, and this concept is then applied and connected throughout the school year to consolidate learning.


As Mathematical language is a key principle of our approach, at the start of each new topic, key vocabulary is introduced, revisited throughout lessons and embedded as the topic progresses. 


Children are taught through the C-P-A (Concrete – Pictorial – Abstract) approach. This allows teachers to show clear modelling and reinforce the learning that is achieved by going back and forth between the representations, building pupils’ conceptual understanding.


Teachers also use a six part lesson structure which allows the lesson to be pacey whilst the children acquire a new skill, apply the skill and deepen the skill within the lesson.


Feedback is given on children’s learning in line with our marking and feedback policy. Formative assessment within every lesson helps teachers to identify misconceptions, the children who are ready for a challenge or the children who need to access support through same-day interventions. 


The Mathematics Mastery approach allows children to develop their mathematical fluency whilst being able to apply this knowledge through reasoning and problem solving. Therefore, children are able to move between different contexts and representations of maths flexibly. They are also able to show a concept in multiple ways, use mathematical language to explain their ideas and can independently apply the concept to new problems in unfamiliar situations. 


Pupils need to be fluent, but that fluency must encompass understanding and be accompanied by reasoning and problem solving.
