Mathematics at Durham Johnston School

The Mathematics department at Durham Johnston consists of 9 full time teachers and two part-time teachers. We are also supported by a member of the leadership group who teaches 9 hours per week. All members of the department have both mathematics and teaching qualifications and the department is able to offer a complete range of mathematics courses at all levels. Students also have the opportunity to take part in national mathematics contests and our students have a very good record of success.

Students receive three lessons of maths per week in year 7,8 and 9. In each Year we cover the five main areas of mathematics. Number, Geometry and Measures, Ratio and Proportion, Algebra and Data Handling.

KS3 Mathematics

KS3 Setting

In year 7 the students are arranged into three bands; 7X, 7Y and 7Z. This reduces to two bands in Years 8 and 9.

The table below shows the change in sets from year 7 into 8.

We are currently following AQA GCSE Specification (8300).

Assessment Details

A-Level 2017 Onwards

The mathematics department will be following the OCR Linear specifications for A level maths and further maths.

We have chosen Mathematics A H230/240

We have chosen Further Mathematics A H235/H245

These are new courses that started in September 2017. All year 12 students of mathematics or further mathematics will take the AS exam in the summer of year 12.
