# Maths

The teaching of Mathematics at Westfield Academy aims to encourage students, regardless of their Key Stage to:

• Develop their understanding of mathematics and mathematical processes in a way that promotes confidence and fosters enjoyment.
• Develop abilities to reason logically and recognise incorrect reasoning, to generalise and to construct mathematical proofs.
• Extend their range of mathematical skills and techniques and use them in unstructured problems.
• Develop an understanding of coherence and progression in mathematics and of how different areas of mathematics can be connected.
• Recognise how a situation may be represented mathematically and understand the relationship between ‘real world’ problems and standard, and other mathematical models and how these can be refined and improved.
• Use mathematics as an effective means of communication.
• Acquire the skills needed to use technology such as calculators and computers effectively, recognise when such use may be inappropriate and be aware of limitations.
• Develop an awareness of the relevance of mathematics to other fields of study, to the world of work and to society in general.
• Take increasing responsibility for their own learning and the evaluation of their own mathematical development.

## Key Stage 3

## Key Stage 5

The department offers the following A-Level Mathematics course: Pearson Edexcel Level 3 Advanced GCE in Mathematics (9MA0).

This two-year course builds directly on the foundation of the GCSE Higher Level syllabus. It pre-supposes skills in basic algebraic manipulation and the ability to work logically through multistage problems to further develop mathematical understanding. Students are encouraged to think, act and communicate mathematically, providing them with the skills to analyse situations in mathematics and elsewhere. The mathematical knowledge gained will be broad and widely applicable, preparing students for a range of destinations in Higher Education and employment.

The A-Level specification has 3 components:

Year 1: Pure Mathematics 1 (Weighting: 33 1/3%)

• Indices and surds, polynomials, coordinate geometry, trigonometry, sequences and series, algebra and functions, differentiation and integration, numerical methods, exponentials and logarithms, proof, vectors

Year 2: Pure Mathematics 2 (Weighting: 33 1/3%)

• All Pure Maths content as above

Years 1 & 2: Applied Maths - Statistics & Mechanics (Weighting: 33 1/3%)

• Sampling, interpretation in context, standard deviation, binomial and normal distributions, hypothesis testing, use of large data sets, conditional probability (50% of paper)
• Newton's laws of motion, kinematics of motion in a straight line and under gravity, equilibrium of a particle, force as a vector and resolving forces, projectile motion, moments (50% of paper)

Regular assessment takes place, usually half-termly, to ensure students remain on top of their studies, with mock exams taking place in the Spring term. Final assessment is by three external written examinations of duration two hours each at the end of the two-year course, with no coursework.

##### Key Stage 5 Further Mathematics

The study of further mathematics adds breadth and depth to the topics covered in A-Level Mathematics. It introduces new topics, for example matrices and complex numbers. Such topics form an important part of maths-rich degrees in areas such as the sciences, engineering, statistics, economics and computing, in addition to mathematics itself. Some prestigious universities now require a Further Mathematics qualification.

The department currently offers Pearson Edexcel Level 3 Advanced GCE in Further Mathematics (9FM0). The specification has 4 components:

1: Mandatory Core Pure Mathematics 1 (Weighting: 25%)

• Proof, complex numbers, matrices, further algebra and functions, further calculus, further vectors, polar co-ordinates, hyperbolic functions, differential equations, trigonometry

2: Mandatory Core Pure Mathematics 2 (Weighting: 25%)

• Any of the pure mathematics above

3: Option 1 (Weighting: 25%)

4: Option 2 (Weighting: 25%)

Regular assessment takes place, usually half termly, to ensure students remain on top of their studies, with mock exams taking place in the Spring term. Final assessment is by four external written examinations of duration 1.5 hours each at the end of the Upper Sixth, with no coursework.

## Exams & Assessment

• A-Level Further Mathematics course: Pearson Edexcel Level 3 Advanced GCE in Further Mathematics (9FM0)
##### Exams

Year 7 baseline test is conducted on the second week of Term 1.1. This provides data for groupings. In general, Term 3.2 of the previous year's testing provides a baseline for the current year, Term 1.2 and 2.2 tests provide mid-year data to identify whole cohort progress and students who need further support and intervention. End of year (Summer) tests gives the final judgement for the year.

Exam Timeline:

• Term 1.2
• Term 2.2
• Term 3.2

## Enrichment & Extracurricular

The Maths department regularly take part in country and national level competitions and challenges with recent accomplishments including winning the Maths Challenge Hertfordshire Maths Challenge in 2021 with Year 8.

• Many students participate in the Junior, Intermediate and Senior Maths Challenge from the UK Mathematics Trust and many achieve medals, with a significant number qualifying for the subsequent rounds.
• Hans Woyda Prep Club for Years 8-13 takes place each Monday lunchtime. Hans Woyda is a prestigious maths competition which takes place each year and students from the Academy have been very successful over the years.
