The Importance of Mathematics

Maths is important for all members of modern society. Mathematical thinking and the use of mathematical techniques is part of the essential equipment that all students need to enter the world of work and decision making.

We believe that Maths should also be a stimulating and enjoyable experience for all of our students, helping them to learn the basic skills and to develop the ability to solve problems in a creative way.

We strive to create an atmosphere where students are challenged and encouraged to do their best.

Course Aims

In Years 7, 8 & 9 students pursue a course in Mathematics in line with the new National Curriculum. In these first three years of secondary school Mathematics we aim to enthuse and encourage all students. During KS3 we lay the foundations in algebra, number, geometry and data handling for work at GCSE level.

We encourage students to think mathematically and we offer them appropriate challenges throughout.
