GCSE Year 10 Topic List (Higher)

GCSE Year 10 Topic List (Foundation)

Mathematics is a core subject in the National Curriculum.

The understanding of the processes used in Mathematics is the key to success; this is essential since the introduction of the Functional Mathematics element of the curriculum.

A variety of teaching and learning styles is used: individual, paired and group activities requiring oral, written and practical work. Textbooks, worksheets and software are used as appropriate. The students are expected to take on the challenges of extension work appropriate to them; however, confidence and enjoyment are paramount if they are to work with determination.

The students’ ability to reason mathematically and solve problems is nurtured through their learning. Number, Algebra, Shape, Space and Measures, and Data Handling (including Probability) are the key strands of learning during Key Stage Three. At Key Stage Four, the focus of learning remains the same but along with preparation for the GCSE examination.

At the end of Key Stage Four, the students are encouraged to take the opportunity to gain two GCSE qualifications in Mathematics: GCSE Methods in Mathematics and GCSE Applications of Mathematics. Should it be more appropriate, a student will be advised to take the single GCSE qualification. We are currently using the OCR examination board.

Mathematics is a creative and highly interconnected discipline that has been developed over centuries, providing the solution to some of history’s most intriguing problems. It is essential to everyday life, critical to science, technology and engineering, and necessary for financial literacy and most forms of employment. A high-quality mathematics education therefore provides a foundation for understanding the world, the ability to reason mathematically, an appreciation of the beauty and power of mathematics, and a sense of enjoyment and curiosity about the subject.

- become fluent in the fundamentals of mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and the ability to recall and apply knowledge rapidly and accurately
- reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, justification or proof using mathematical language
- can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions

Mathematics is an interconnected subject in which pupils need to be able to move fluently between representations of mathematical ideas. The programmes of study are, by necessity, organised into apparently distinct domains, but pupils should make rich connections across mathematical ideas to develop fluency, mathematical reasoning and competence in solving increasingly sophisticated problems. They should also apply their mathematical knowledge to science and other subjects.

The expectation is that the majority of pupils will move through the programmes of study at broadly the same pace. However, decisions about when to progress should always be based on the security of pupils’ understanding and their readiness to progress to the next stage. Pupils who grasp concepts rapidly should be challenged through being offered rich and sophisticated problems before any acceleration through new content. Those who are not sufficiently fluent with earlier material should consolidate their understanding, including through additional practice, before moving on.

Mathematics is an interconnected subject in which pupils need to be able to move fluently between representations of mathematical ideas. The programme of study for key stage 3 is organised into apparently distinct domains, but pupils should build on key stage 2 and connections across mathematical ideas to develop fluency, mathematical reasoning and competence in solving increasingly sophisticated problems. They should also apply their mathematical knowledge in science, geography, computing and other subjects.

Decisions about progression should be based on the security of pupils’ understanding and their readiness to progress to the next stage. Pupils who grasp concepts rapidly should be challenged through being offered rich and sophisticated problems before any acceleration through new content in preparation for key stage 4.
