Mathematics

Core Mathematics

Mathematics at Year 9 has a key focus on the students developing their skills via engaging, inquiry-based learning activities and reflecting on their learning habits to identify opportunities for further improvement. 

Content

The course also aims to provide an appropriate balance between the mathematical skills students should acquire at Year 9 level and the authenticity of the skills they are learning. Students undertake a range of modelling and application activities, so the classroom Mathematics can be put into context as authentic situations are presented. It is the intention, wherever possible, to provide student centred learning opportunities that link Mathematics to real life situations and engage them to see Mathematics in a broader perspective. 

Dimensions/ Number and Algebra 

They solve problems involving linear equations and inequalities, quadratic equations and pairs of simultaneous linear equations and related graphs. Students substitute into formulas, find unknown values, manipulate linear algebraic expressions, expand binomial expressions and factorise monic and simple non-monic quadratic expressions, with and without the use of digital technology. They represent linear, quadratic and exponential functions numerically, graphically and algebraically.

Measurement and Geometry

Students solve and explain surface area and volume problems relating to composite solids. They use parallel and perpendicular lines, angle and triangle properties, similarity, trigonometry and congruence to solve practical problems and develop proofs involving lengths, angles and areas in plane shapes. 

Statistics and Probability 

Students compare univariate data sets by referring to summary statistics and the shape of their displays. They describe bivariate data where the independent variable is time and use scatter-plots generated by digital technology to investigate relationships between two continuous variables. Students evaluate the use of statistics in the media. 

Special Conditions

Students should retain their CAS (computer algebra system) calculator from Year 9 as it will be a key resource for their Year 10 and subsequent VCE maths studies. 

Assessment

All students will complete CATs, topic tests, problem solving tasks, regular homework assignments and two end-of semester exams. 

Additional

Students will be encouraged to enter/participate in the Maths Extension and Enrichment Activities in class and in external set competitions such as ICAS, University of Melbourne and the Australian Maths Challenge.
