Mathematics

Head of Department

Mr N Riseborough BSc (Hons), PGCE

Statement of Intent

At the core of everything we do is the ideal that mathematics at DHSG should be an exciting adventure where our students are guided to discover the richness and variety of our subject.

Though our bespoke and ambitious curriculum, we aim to stimulate our students’ interest in and enthusiasm for mathematics, with a commitment to fostering a positive attitude towards their studies.

Whilst striving to grow a love of studying mathematics for its own sake, it is important that our girls recognise the diverse applications of our subject and how it underpins almost every area of the wider curriculum, from the more obvious science and computing links, through to the music and art subjects.

Our curriculum offer is much more than teaching the skills required for the GCSE. We teach our girls to ask questions, think critically, and respond with brave reliance when faced with unfamiliar situations.

It is our intention that at the end of middle years, all girls have a positive view of mathematics and are confident and fluent with the curriculum. Girls will have outstanding foundations for any further study and, importantly, enter the world beyond school as highly numerate citizens.

Middle Years Exam and Specification Information

All students follow the new Edexcel GCSE (Higher) mathematics course. Whilst we do set by ability, all students 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 E dexcel website GCSE Mathematics Specification

Extra-curricular activities

200 students 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.
