Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.

#### Subject overview

Mathematics is a creative and highly inter-connected discipline that has been developed over centuries, providing the solution to some of history’s most intriguing problems. It is essential to everyday life, critical to science, technology and engineering, and necessary for financial literacy and most forms of employment. A high-quality mathematics education therefore provides a foundation for understanding the world, the ability to reason mathematically, an appreciation of the beauty and power of mathematics, and a sense of enjoyment and curiosity about the subject.

Students are encouraged to make plenty of contributions in lessons, to listen carefully to the ideas of others, and to critically reflect upon contributions. We explicitly teach learners the appropriate ways to talk like mathematicians, and to listen to one anothers' ideas and reasoning.

#### Key Stage 3 Mathematics overview

We follow the National Curriculum for Mathematics at Key Stage 3.

Students build on their KS2 study, and are taught to:

• Develop fluency
• Reason mathematically
• Solve problems

We teach the following topics:

• Number
• Statistics
• Probability
• Geometry and measures
• Ratio, proportion and rates of change
• Algebra

#### Key Stage 4 Mathematics overview

We follow the Edexcel specification for Mathematics. All students are entered for either the Foundation tier or the Higher tier GCSE at the end of Year 11.

The Edexcel GCSE encourages learners to develop confidence in, and a positive attitude towards, mathematics, and to recognise the importance of mathematics in their own lives and to society. It also provides a strong mathematical foundation for learners who go on to study mathematics at a higher level post-16. This specification enables learners to:

• develop fluent knowledge, skills and understanding of mathematical methods and concepts
• acquire, select and apply mathematical techniques to solve problems
• reason mathematically, make deductions and inferences and draw conclusions
• comprehend, interpret and communicate mathematical information in a variety of forms appropriate to the information and context.
