Maths
The teaching of Mathematics at Watford Grammar School for Boys aims to encourage students, reflecting 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
At Key Stage 3 pupils consolidate their existing mathematical understanding from Key Stage 2 and extend their knowledge of number, algebra, geometry and statistics as detailed below. Students are taught Mathematics in sets by ability level and the lower ability students follow a moderated curriculum. There are half termly progress tests for assessment and setting purposes along with end of year tests.

Key Stage 4
Key Stage 4 is a threeyear course following the Edexcel Exam Board, Higher Linear 1MA1. In May/ June of year 11 there are 3 exam papers (one calculator and two noncalculator) with an emphasis on problem solving and showing mathematical method. Students are taught Mathematics in sets by ability level. The top 3 sets follow an accelerated course to include an additional AQA Further Mathematics (Level 2) course which is two exams ( a calculator and a noncalculator) in the summer term of Year 11.
The lower sets follow the same curriculum and sit the Edexcel exams but with a moderated pace and expectation to match their ability. Some students will sit the Foundation papers instead of the Higher papers.
There are half termly Progress Tests and Mock GCSE exams in Year 11. The course can be summarised as follows:

Key Stage 5
The department offers the following A Level Mathematics course: Pearson Edexcel Level 3 Advanced GCE in Mathematics (9MA0)
This twoyear course builds directly on the foundation of the GCSE Higher Level syllabus. It presupposes 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:

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 3 external written examinations of duration 2 hours each at the end of the Upper 6th, with no coursework. Further details are available in the Edexcel specification document here.
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 mathsrich 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 skills gained are readily applicable to the problems that they will encounter in their A Level courses, further study, life and employment.
The course is assessed by two 90 minute papers and has the following content:
Compulsory content: Analysis of data, Maths for personal finance, Estimation, Critical analysis of given data and models 
Optional content (at least three of these must be studied): The normal distribution, Probabilities and estimation, Correlation and regression, Critical path and risk analysis, Expectation, Cost benefit analysis, Graphical methods, Rates of change, Exponential functions
