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 students 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 students 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 3  (Year 7 and 8)  

Our students follow a bespoke five-year curriculum pathway to meet the needs of our selective cohort. Whilst we do not differentiate between KS3 and KS4, all elements of the KS3 curriculum are met by the end of year 9.

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.
