Purpose

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 4 distinct domains, which we label as Number, Algebra, Geometry and Data. Pupils should build on their existing knowledge and skill from  Key Stage 2 and make 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, Computer Science and other subjects.

Content

Year 9 consolidates and extends students' knowledge, preparing them for GCSE. In Number, students deepen their understanding of standard form and indices, percentages, and errors in measurement. Algebra becomes more sophisticated, with a focus on solving simultaneous equations, introducing quadratics, and inequalities, as well as understanding graphical representations. In Shape, students study Pythagoras’ theorem, trigonometry, and more advanced geometry, including circles and loci. Statistics focuses correlation and working with grouped data, while Probability introduces tree diagrams and theoretical probabilities. Problem-solving and reasoning are central, ensuring students develop the analytical skills and confidence to excel in Years 10 and 11.
