The Mathematics Department at West Hill School aim to expose all boys to a wealth of mathematical skills, enabling them to approach real world issues in a logical and analytical way. This is realised through quality teaching and learning experiences, teamed with boys growing independence and resilience in their mathematics journey.

Year 7

Lesson contact time is 3 hours per week.  The topics followed are:

  • Number – Enhancing numeracy skills; Working with fractions, decimals and percentages; Special numbers.
  • Algebra – Simplifying expressions and solving equations; co-ordinates; graphs.
  • Shape – Area and Perimeter of 2D shapes; Volume of 3D shapes; Transformations; exploring angle sums.
  • Probability - Introducing probability and using it to predict outcomes.
  • Ratio, proportion and rates of change – Introducing ratio; Solving ratio problems and introducing simple proportion problems.
  • Statistics- Averages; Collecting and representing data.

Year 8

Lesson contact time is 4 hours per week.  We build on the topics in year 7 and extend on to the following topics in preparation for the GCSE course:

  • Number – Compound interest; calculating percentage change.
  • Algebra – Expanding and factorising expressions; algebraic problem solving and forming equations; Plotting linear/quadratic functions; simultaneous equations; nth term of sequences.
  • Shape – Plans and elevations; Enlargements using fractional scale factors; construction and loci.
  • Probability – mutually exclusive outcomes; probability of successive events.
  • Ratio, proportion and rates of change – Using proportional reasoning; direct proportion problems.
  • Statistics- Types of data; cumulative frequency; scatter graphs; averages from grouped data and frequency tables.

Year 9

Lesson contact time is 4 hours per week. We begin the new specification GCSE in year 9 to allow for the increase in content. Topics covered in this year include:

  • Number: Prime factorisation, Highest Common Factor (HCF) and Lowest Common Multiple (LCM).
  • Algebra: Compound measures; solving quadratic equations; manipulating basic formulae.
  • Shape: Angles in polygons; the circle theorems and Area/ Circumference of circles/sectors.
  • Ratio, Proportion and rates of change: Growth and decay problems; Expressing ratios as linear functions and similar shapes.
  • Statistics: Venn diagrams and sampling.

Year 10

Lesson contact time is 4 hours per week. We continue covering the GCSE in year 10 and some of the topics covered in this year include:

  • Number: Surds, index laws and standard form.
  • Algebra: Graphical intersections; plotting cubic and reciprocal graphs and exploring gradients of perpendicular and parallel lines
  • Shape: Volume and surface area of cones, spheres, cylinders and pyramids; area and perimeter of sectors and calculating using multiples of pi.
  • Ratio, Proportion and rates of change: Direct and inverse proportion problems.
  • Statistics: Cumulative frequency and histograms.
  • Probability: tree diagrams and relative frequency.

Year 11

Lesson contact time is 4 hours per week. The GCSE course is finished and teachers will identify key areas to revisit in order to prepare your son for his examination. We use internal & external assessment to identify key areas for individual students to build on. Topics covered in this year include:

  • Number: Bounds and fractional indices.
  • Algebra: Iteration, composite functions, proof and geometric progressions.
  • Shape: Vectors, Trigonometric graphs, Pythagoras and trigonometry in three dimensions.
  • Ratio, Proportion and rates of change: applying the concepts of instantaneous and average rates of change by looking at the gradients of tangents and chords to a curve.
  • Statistics: Estimating the median from a histogram.
  • Probability: Using algebra to solve probability tree diagrams.


To support your son’s learning and engagement in this subject he needs to have:  a pen, a pencil, a ruler, a rubber, a pair of compasses, a protractor and a calculator. We recommend an up to date Casio model.


To support your son, resources are available on the school’s VLE,  We also make use of the website  In Years 10 and 11 we recommend boys use the Corbett maths website as it contains topic-specific questions to focus their studies:

  • We sell the new specification Collins All-in-one practice revision books for £4, Higher and Foundation to key stage four pupils.
  • We recommend that pupils download and use the PiXL maths & Times Table APPs for smartphones, tablets or desktop computers.

GCSE Mathematics Examination Tips


In years 9, 10 and 11 pupils follow the AQA 8300 course.  This course is assessed by examinations only at the end of Year 11.  The exam is based on three papers – 1 non-calculator paper and 2 calculator papers.  Further details are available from the examination board here:
