Devonport High School for Girls

Name of Head of Department

Mr N Riseborough BSc (Hons), PGCE

Introduction to the department

It is our hope that mathematics at DHSG should first of all be fun. We wish to stimulate interest in, and enthusiasm for, the study of mathematics for its own sake so that girls discover for themselves the richness and variety of the subject and the unique insight it provides into the nature of the world around them. This is not to overlook the development of the skills required for adult life, other subjects, and the passing of examinations but is intended to demonstrate our commitment to the fostering of a positive attitude to the subject. We also aim to provide girls of varying abilities and interests, the opportunity to achieve their full potential in the subject at an appropriate level and rate of progress.

Key stage 4 (Year 9, 10 and 11) 

All students follow the new Edexcel GCSE (Higher) mathematics course. Whilst we do set by ability, all girls follow the same scheme of work and sit the same assessments. All students have the opportunity to achieve the highest grades.

Details can be found here:

Full details of the specification and assessment criteria can be found on the Edexcel website GCSE Mathematics Specification

Extra-curricular activities 

200 pupils every year take part in the junior, intermediate and senior mathematics challenges.

The department run a mathematics club on a lunchtime. Students from this group are selected for the Mathematics Challenge team. The school have been regional junior champions on a number of occasions.
