• Number: Fractions, decimals, ratios, and percentages in real-life settings that include money-related matters like GST, interest, salaries and commission cost- and selling price. 

• Measurement: Perimeter of compound shapes, area of composite shapes, surface area of 3D shapes and volume.

• Algebra: Write expressions and equations, simplify, expand and factorise expressions, and solve multi-step equations and patterns.

• Probability: Use the Statistical enquiry cycle to investigate chance-based scenarios and express chance as a probability, Venn diagrams and probability trees.

• Space: Angle rules, angles, bearings, constructions and transformations

• Statistics: Statistical enquiry cycle(PPDAC) - Evaluate a problem, Create a plan to investigate, collect data to calculate central tendencies and create visual presentations, analyse the data to make informed conclusions.
