In Year 9 Mathematics, learners compare rational and irrational numbers, identify positions on a number line and apply understanding to express solutions to problems in exact and approximate form. They manipulate variables of functions and represent real situations graphically and algebraically to interpret solutions to inform behaviours and decisions. Learners use mathematical modelling in a range of contexts, including making predictions and developing insights about the economy, financial systems and financial choices to inform personal financial decisions. They use efficient methods for simplifying and solving problems involving exponent notation and laws in various contexts and verify the reasonableness of solutions.
Learners communicate and justify solutions to geometrical problems using coordinates in the Cartesian plane. They explain how the results of calculations depend on accurate measurement and how they are affected by using approximation. Learners deduce and justify choices of formulae to determine and quantify spatial relationships and trigonometric ratios.
Learners use sampling techniques and representations of data to support or refute conclusions or to promote a point of view. They design experiments to represent likely outcomes of events, drawing conclusions to inform and predict decisions.
Learners develop a productive disposition to mathematics through experiences which prompt curiosity. They reflect on and explain their thinking and embrace their mistakes as part of productive struggle. They view mathematics as understandable, worthwhile and relevant to their lives now and in the future.
