In Year 9, students continue to build on their Maths skills and knowledge via the Maths Pathway learning platform. By this time students should have filled all of the gaps in their knowledge and commenced working towards their senior maths goals.
The following descriptions are an example of what some students will experience in Year 9 (depending on their prior learning).
Areas of study include;
Number: Irrational numbers and basic operations with surds; negative indices and scientific notation; use of ratios in scale drawing.
Space: Construction and properties of 2D and 3D figures; congruency; similarity. Probability: long-run proportion; compound events; simulation; measures of centre and spread; box plots and dot plots
Measurement, Chance and data: Length, area and volume relationships involving triangles, quadrilaterals, circles, prisms and pyramids; Pythagoras’ Theorem; trigonometric ratios and solving right-angled triangles.
Structure: Expanding products of linear factors; factorising quadratic expressions; linear, quadratic and simultaneous linear equations; graphs of linear and quadratic functions.
