Mathematics
The Mathematics department aims to promote the appreciation of the power and beauty of Mathematics within each student and to enable each student to develop their mathematical skills and understanding to the limit of their capability. As mathematics is an essential prerequisite for many other subjects within the school curriculum, the department aims to provide each student with the mathematical background that they require to be able to apply their mathematics successfully in other areas. Also it aims to ensure that all students are aware of the power of a mathematical argument and the need for clear, logical arguments. In an academic school, the need for each student to attain the highest exam result possible for their ability is very important. With this in mind the department tries to ensure that all students are fully aware of the demands of the subject and have experienced a variety of teaching styles to facilitate their learning and can apply their mathematics in examination situations.

In Years 10 and 11, pupils study for the Edexcel IGCSE in Mathematics. All pupils take Higher Level and achieve great success with an average of 58.6% of all pupils obtaining A* (or 8/9) grades and 85.6% obtaining at least an A (or 7) grade in the five years prior to Lockdown and 62.8% obtaining grade 8 or 9 in 2022.
As well as extending the ideas covered during Years 7 to 9, the following new material will be covered over the course of the two years:

For the last eight years, the pupils in the top two sets have also had the chance to sit the AQA Level 2 Certificate in Further Mathematics which provides greater challenge for able mathematicians without accelerating pupils into A level work. The results they have achieved have been very pleasing with 110/315 obtaining A** grades and 147/315 obtaining A* grades prior to Lockdown and 35/37 obtaining grade 8 or 9 in 2022 after a grading structure reorganisation.
Those taking this qualification also cover the following material:
- Algebra - Quadratic identities. Completing the square. The factor theorem. Drawing piecewise continuous graphs and using such graphs to solve equations. Algebraic proof. Limiting values of sequences. Further calculus. Introduction to matrices and matrix transformations.
- Shape and Space - Equations of circles. Solving geometric problems involving circles and straight lines. Geometric proof. Three-dimensional trigonometry. Graphs of trigonometric functions. Solving trigonometric equations. Simplification and application of trigonometric identities.
A Level
Mathematics is the most popular subject in the Sixth Form with between 60 and 90 students opting to study it every year. It is also one of the most successful with an average of 29.7% of students obtaining A* grades and 82.4% A* to B grades in the five years before Lockdown and 59.6% obtaining grades A* or A in 2022.
An A Level in Mathematics is a very valuable qualification and is highly rated by both university tutors and employers. Any student who has enjoyed IGCSE (or GCSE) Mathematics and who feels they would benefit from being challenged by the more in-depth material of A Level Mathematics should consider taking the subject in the Sixth Form. As with any other A Level subject, it should be noted that A Level Mathematics requires hard work and dedication and students should not opt for the subject unless they are prepared to apply themselves fully.
An A grade/ grade 7 at IGCSE/GCSE is a minimum requirement, along with a very good level of fluency with algebra.
All students taking Mathematics at A-level will have 8 or 9 lessons in the Lower Sixth and 9 lessons in the Upper Sixth split between Pure Maths (6 lessons) and Applied Maths (2/3 lessons).
The course followed at Leicester Grammar School is the Edexcel A-level. From September 2017, A-level Mathematics is a linear course with three equally weighted exams taken at the end of the Upper Sixth determining the grade a student obtains. Unlike previous A-level specifications, there is now no longer any choice in the Applied Mathematics that a student will study.
The tables below show some details of the topics that are in each of the three A-level exam papers.

Setting:
Mathematics is fortunate in that all classes occur in the same option block. Hence it is possible to set by ability. It is likely that between 4 and 6 ability sets will be used in each year, usually with between 8 and 14 students in each.
Further Mathematics
To study Further Mathematics in the Sixth Form, a student needs to have real enthusiasm for the subject as twice as much lesson time (and twice as much self-study time) will be spent on Mathematics as compared to other subjects. The most able mathematicians who have found IGCSE/GCSE Mathematics straightforward and who are considering taking university courses in Mathematics, Engineering, Computer Programming or the Physical Sciences should consider this option. As a large part of the Sixth Form timetable will be spent on Mathematics, the coverage of material is very rapid and so a firm grasp of the algebraic skills learnt at IGCSE/GCSE is needed. An A* grade/grade 8 or 9 at IGCSE/GCSE should be a requirement for anyone wishing to follow a course in Further Mathematics.
Students opting for Further Mathematics at Leicester Grammar School with have 16 lessons in the Lower Sixth split between Pure Maths (11 lessons) and Applied Maths (5 lessons). The intention is that Further Mathematics students will take A-level mathematics at the end of the Lower Sixth. In the Upper Sixth, students will have 18 lessons split between Pure Maths (13 lessons) and Applied Maths (5 lessons), although this may depend on any options chosen.
Unlike A-level Mathematics, while half of the course content is compulsory, there is an element of choice in A-level Further Mathematics. It may be the case that students within the class (or classes) have some firm ideas about the areas they wish to pursue and, if this is possible from a timetabling standpoint, there will be the possibility of different students studying different topics. However, this will always be at the discretion of the Head of Mathematics, the Curriculum Deputy and the Headmaster in consultation with the subject teachers.
The table below shows some details of the topics that will be in the two compulsory exam papers together with a brief outline of the most likely optional papers to be taken.

Co-Curricular
The Mathematics Department believes that all pupils should be able to think about how to apply their knowledge of mathematical topics to solve problems. All pupils have the chance to take part in the UKMT Mathematics Challenges (All Year 8 and selected Year 7 in the Junior Challenge, all Year 10 and top set Year 9 in the Intermediate Challenge and all Lower Sixth Maths students and any Upper Sixth Maths students who opt to take it in the Senior Challenge). The department also sends teams to the Team Maths Challenge competitions and in 2012/13 our Junior Team qualified for the National Final and our Year 10 team qualified for the Midlands Final, in 2013/14 our Senior Team qualified for the National Final and our Year 10 team won the Midlands Final and in 2015/16, our Senior Team again qualified for the National Final. In 2018/19 our Junior Team qualified for the National Final.
