It is the mathematics department’s core belief is that every learner should leave De Aston with the ability to engage in the basic numerical and mathematical tasks that real-life will demand of them. Our aim is to provide learners with the skills to access their GCSE examinations in Year 11 with confidence so that they can achieve one of the key qualifications needed to progress to their next stage of education or training.

Learners will have the opportunity to engage in topics that will apply directly to the world around them and will be essential in later life, such as dealing with percentages and ratios, estimation, probability and statistics. Learners will also have the opportunity to challenge themselves with more abstract areas of mathematics that will prove useful in other subjects at GCSE level and beyond, such as algebra, geometry and graphing methods.

In Year 7 and 8 we run a “mastery” scheme of work which is designed to allow students a prolonged period of time covering a single topic in depth. For those who have a good understanding already, it is structured in a way which allows them to think laterally and deepen their understanding through problem solving.

The mathematics department aim to provide learners with a variety of in-class tasks and homework to challenge their understanding of the course content. We also aim to encourage critical thinking and interest in the subject beyond the constraints of the curriculum, after all, mathematics is a vast and interesting subject!

We expect learners to make mistakes. Experiencing them, reflecting on them and learning from them are the hallmarks of a good mathematician.

Head of Department:

Mr J Wood


We aim to have some spare equipment on hand, but cannot always guarantee a full stock. It is requested that learners come equipped with the following equipment in addition to the standard learning tools needed across the school:

  • Ruler
  • Protractor
  • Compass
  • Calculator. We have a stock of school calculators; however, some learners may feel more comfortable having and learning to use their own.


To support learners we run extra sessions in school. We have a Y7, 8 and 9 lunch session and a Y10 and 11 lunch session. After school we offer an additional session for those who cannot make the dedicated lunch sessions. Information and letters about these booster sessions can be obtained from the Head of Department, Mr Wood.

To challenge learners we seek to enter into the UKMT Mathematics team challenges and the FMSP Maths Feast at all age groups. We also provide the opportunity for learners to challenge themselves individually in the UKMT Mathematics individual challenges. There are a variety of additional trips that we offer to students to both challenge their understanding and engage interest in the subject, depending on availability.

  • Addition and subtraction
  • Multiplication and division
  • Angles
  • Fractions
  • Algebra and sequences
  • Data and percentages


  • Factors, roots, powers and mixed numbers
  • Negative numbers and sequences
  • Accurate drawings and quadrilaterals
  • Percentages and ratio
  • Circles and 3D shapes
  • Statistical graphs


In Year 9 learners begin to work on the topics examined at GCSE level, essentially beginning their 3 year Edexcel GCSE course in mathematics (1MA1). Learners will cover a broad variety of content in each of the mathematical disciplines depending on whether they are studying for the higher or foundation tier exam.

Higher tier assessments consist of approximately:
  • 15% number questions
  • 30% algebra questions
  • 20% ratio and proportion questions
  • 20% geometry questions
  • 15% statistics and probability questions
Foundation tier assessments consist of approximately:
  • 25% number questions
  • 20% algebra questions
  • 25% ratio and proportion questions
  • 15% geometry questions
  • 15% statistics and probability questions

At the end of Year 11 learners take three 90 minute exams with questions covering a mixture of topics from across the 3 year course. There will be one non-calculator exam: in the remaining two exams calculators are allowed. All three exams contribute equally to the learner’s final grade.

Further details of the course content and the assessment procedures can be found on the Edexcel website:


In Year 12 learners can choose to continue their studies with the A-level mathematics course: a 2 year Edexcel Level 3 Advanced GCE course (9MA0). Learners will have the opportunity to study a variety of disciplines within the subject including advanced algebraic methods, algebraic and numerical calculus, statistical methods and mechanics.

The “pure mathematics” topics studied include:

  • Proof
  • Algebra and functions
  • Coordinate geometry
  • Sequences and series
  • Trigonometry
  • Exponentials and logarithms
  • Differentiation
  • Integration
  • Numerical methods
  • Vectors

The “applied mathematics” topics studied include:

  • Statistical sampling
  • Data presentation and interpretation
  • Probability
  • Statistical distributions
  • Statistical hypothesis testing
  • Quantities and units in mechanics
  • Kinematics
  • Forces and Newton’s laws
  • Moments

At the end of Year 13 learners take three 2 hour exams. Paper 1 and 2 focus on the pure mathematical elements of the course and can pose questions from any of the topics listed above. Paper 3 focuses on the applied mathematical elements and is split into two sections: one examining statistics, the other examining mechanics. All three papers allow the use of a calculator and contribute equally to the learner’s final grade.
