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

Subject overview
Mathematics is a creative and highly interconnected 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 highquality 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 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 post16. 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.
Please look at the Edexcel specification for more information about the course content.
