Year 9 Mathematics develops more advanced thinking and independence. Students work with linear and nonlinear relationships, expand and factorise expressions, and solve equations that model real-world situations. They use graphs to understand patterns of change in areas such as finance, science and everyday problemsolving. Students apply Pythagoras’ theorem and trigonometry in practical contexts, and strengthen their ability to analyse and interpret data. The focus is on reasoning, justification and tackling more complex problems with confidence in preparation for senior mathematics pathways.
Unit 1: Algebra and Cartesian Plane Students will extend on their index laws and apply them to calculations involving scientific notation. Students will use algorithms to explain geometric constructions. Students will revisit Pythagoras and be introduced to Trigonometric ratios to solve problems.

Unit 2: Measurement and Geometry Students will solve problems involving direct proportion ratio and scale and communicate their findings. They will apply enlargement transformation to images and objects. Students will have to recall and apply Trigonometry to show similarity. They will solve problems involving surface area and volume of right prisms and cylinders.

Unit 4: Statistics and Probability Student will investigate how sampling techniques can be used to support conclusions. They will compare numerical data sets by calculating summary statistics and comparing shapes of distribution. Students will investigate compound events and assign probabilities. They will conduct probability experiments and compare results.
