Much of our everyday lives and work has mathematics at its heart. It encompasses applying mathematical techniques to routine procedures, problem solving, presenting arguments which may be justified by proofs alongside interpreting solutions in the context of the problem at hand. At St Mary’s we aim to provide an expertly devised varied curriculum which teaches techniques whilst engaging and inspiring students to apply these skills to real life problems which extend to other subject areas. Additionally we offer chances for enrichment through lunchtime clubs, external group competitions as well as individual challenges which are conducted internationally. We offer a regular lunchtime help club where students of all ages and abilities are encouraged to seek any support or help with individual questions or topic areas.

Key Stage 3

In Key Stage 3 pupils follow the programs of study prescribed by the National Curriculum. They learn new techniques in each of the set areas of Number & Measure, Geometry, Algebra, Statistics, Probability, Ratio and proportion and Rates of Change and apply these to problems. We challenge and extend their thinking often going beyond that set out below. The pupils are encouraged to explain their thinking and to set this down on paper. They meet simple proofs and are encouraged to develop their talents of reasoning, interpretation and problem solving in the context of real life problems. More detail as to the content is set out below.

Key Stage 4

In Key Stage 4 students follow the prescribed National Curriculum which is assessed by Edexcel Examination Board. Students are entered for either Higher Level leading to grades 4 – 9 or Foundation level leading to grades 1 – 5. The vast majority of the course builds upon and extends the skills learned at KS3, but students do encounter and develop new areas of mathematics. Particular emphasis is to be able to confidently:
· Accurately recall facts and carry out routine procedures or set tasks requiring multi-step solutions. · Present arguments and proofs. · Make deductions, inferences and draw conclusions from mathematical information from mathematical information. · Interpret and communicate information accurately in the context of the given problem. · Evaluate methods used and results obtained. · Evaluate solutions to identify how they may have been affected by assumptions made. Assessment is by three separate 1 ½ hour written examinations at the end of the course. Paper 1 is non-calculator and Papers 2 & 3 require the use of a scientific calculator. The three papers are equally weighted. Those topic areas which are totally new to the tiers of entry are:

Key Stage 5

Students who opt to study either Mathematics or Further Mathematics follow the Edexcel syllabus for both. These exciting subjects extend the knowledge and reasoning acquired thus far and challenge the students’ application and evaluation to a greater and much deeper level.
The A level Mathematics course builds upon the three areas of Pure Mathematics, Statistics and Mechanics. The students will expand their knowledge of Proof

For A level Further Mathematics the exam board is also Edexcel. The subject code is 9FM0. For further details please visit
