# Mathematics

## Year 9 Mathematics

Mathematics equips pupils with a powerful set of tools to understand and change the world. These tools include logical reasoning, problem solving skills and the ability to think in abstract ways. Thorpe House School Mathematics Department will provide for every boy an opportunity to benefit from mathematical experiences, which will help them acquire the skills and understanding required for other subjects studied and in everyday life. It reflects the essential part that mathematics plays in education.

## Enrichment

Year 9 students will have the opportunity to go and visit Bletchley Park which is a place of exceptional historical and mathematical importance. It is the home of British codebreaking for World War Two and a birthplace of modern information technology.

Students will also have the opportunity to compete in the UK Intermediate Maths Challenge (UKMT).

## Facilities

Our Mathematics classroom has been designed with large white boards around the room to encourage student’s enthusiasm about maths in a more practical way. Laptops and Ipads are used on a regular basis to enhance student’s understanding of each topic.
