In Year 9, students continue to develop strong mathematical skills and positive attitudes as they deepen their understanding of integer and rational number systems. They strengthen fluency in mental calculations, written methods, and digital tools, while routinely checking the reasonableness of results in context.

They use exponents and exponent notation to formalise their understanding of natural number representations and make conjectures involving natural numbers, supported by experiments and digital tools.

Students recognise, develop, and use algebraic expressions and formulas, following conventions and using appropriate notations and symbols. They interpret and evaluate these expressions through substitution, find unknown values, and solve simple equations using various methods.

They apply mathematical modelling to solve practical problems involving rational numbers, ratios, and percentages, carefully choosing representations and strategies, and clearly communicating solutions within context.

Students use variables, constants, relations, and functions to represent relationships in real-life data, interpreting key features through rules, tables, and graphs.

They extend their understanding of angles to discover new relationships and apply these in measurement and spatial problem-solving.

Students create and use algorithms to classify plane shapes and use tools to construct shapes, including two-dimensional representations of prisms and other objects.

They describe transformations using coordinates in the Cartesian plane.

Students apply the statistical investigation process to collect numerical data related to questions of interest, select suitable displays for data distributions, and interpret summary statistics to determine the centre and spread in context.

Finally, they conduct probability simulations and experiments involving chance events, construct sample spaces, observe frequencies, and compare expected, simulated, and experimental results.
