Year 11 Mathematics Standard

TERM 3, 2025

Interest and Depreciation (continued)

Students will determine the outcomes and probabilities for multistage experiments, calculate simple interest for different rates and periods, calculate the depreciation of an asset using the straight-line method and use a spreadsheet to calculate and graph compound interest as a recurrence relation involving repeated applications of simple interest.

Linear Relationships

Students will model, analyse and solve problems involving linear relationships, including constructing a straight-line graph and interpreting features of a straight-line graph, including the gradient and intercepts. They will construct and analyse a linear model, graphically or algebraically, to solve practical direct variation problems, including the cost of filling a car with fuel or a currency conversion graph.

Working with Time

Students will learn how to indicate positions on the Earth’s surface using latitude, longitude or position coordinates and calculate times and time differences around the world. This will include understanding and using the link between longitude and time to find time differences, solving problems involving time zones in Australia and in neighbouring nations and solving problems involving Coordinated Universal Time (UTC), and the International Date Line (IDL).

Budgeting and Household Expenses

Students will interpret and use information about a household’s electricity, water or gas usage and related charges and costs from household bills, plan for the purchase, running and maintenance of a car and prepare a personal budget for a given income, taking into account fixed and discretionary spending.
