Our School


Maths at St. Peter’s


At St. Peter’s, our aims, vision and values are at the core of everything we do.

We are guided by the key message of our Mission Statement,


'If we follow Jesus, the world will follow us.'


They define our teaching and learning, and provide an environment which prepares our pupils as confident, capable, resilient and responsible citizens able to enjoy a healthy life to the full.


Our inclusive school community works in partnership to meet the responsibility of developing each child in every way – spiritually, emotionally, academically, physically and socially because each child who is a unique creation of God and loved by God, deserves this.


We deliver the Maths curriculum through the unique approach of the St. Peter’s Family and our St. Peter’s five key driver words: Faithful, Confident, Responsible, Resilient and Healthy.


Why is Maths important at St. Peter’s?

  • Mathematics is essential to everyday life.  Therefore, Mathematics at St Peter’s Catholic Primary School teaches children how to make sense of the world around them through developing their ability to calculate, investigate, reason and solve problems.
  • Through their growing knowledge and understanding, children develop fluency within the subject, as well as a deeper understanding of the mathematical processes they use on a daily basis and why they use them. 
  • Through a strong problem solving and reasoning approach to Maths at St. Peter’s, all children develop their mathematical reasoning, encouraging children to think about the mathematical processes that they are using and find explanations as to how they came to their answers.
  • Pupils develop an enjoyment of learning through practical activity and regular problem solving, investigation, exploration and discussion;
  • Children develop fluency and flexibility within Mathematics, enabling children to make links between ideas, methods, strategies and concepts, therefore developing transferable mathematical skills;
  • Maths at St. Peter’s allows children to regularly engage in real problems, enabling them to actually make sense of maths;
  • Pupils develop curiosity in seeking solutions and exploring patterns.
  • Children develop confidence, responsibility and resilience when seeking solutions, working through problems and following a line of enquiry.
  • Maths promotes confidence and competence with numbers and the number system;
  • Children learn to understand relationships and patterns in both number and geometry in their everyday lives.
  • Children learn to appreciate the contribution made by many cultures to the development and application of Mathematics.
  • Pupils develop a practical understanding - in relation to statistics, ratio, proportion and algebra - of the ways in which information is gathered and presented.
  • Pupils explore features of geometry (shape and position), and develop measuring skills in a range of contexts.
  • Children see Maths as an important part of everyday life, understand that we use Maths in everything that we do, which aids the development of the cross-curricular use of mathematics in other subjects.

What are the key Maths subject discipline skills?

  • become FLUENT in Mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and the ability to recall and apply knowledge rapidly and accurately.
