In Number and Algebra, Units of Work

This task addresses some of the burning questions most teenagers have: “How much will I earn when I leave school?” and “How much will it cost to buy a car?”, along with some of the more essential questions young people forget to ask… such as “How much will I be taxed?”, “How much will it cost to borrow money?”

This alternate assessment task in Financial Mathematics has been developed for Year 10 students, or for Year 9 at challenge level. It is mapped against the Australian Curriculum (Mathematics) and the NSW Mathematics Syllabus (Stage 5.1 & 5.2) and it includes a marking rubric and a teacher’s marking calculator (in Microsoft Excel format) with which to generate marking responses based on selected student variables.

Concepts covered include calculating gross and net wages before and after tax; operating and solving problems using simple and compound interest; and making valid comparisons between total accumulated costs and the initial (principal) amounts of money borrowed or invested.
