Ten more 25-minute consumer-arithmetic lessons, Days 21–30. Start with the teacher scripts, provide learner Cards H–N, and choose from 20 optional context swaps. Day 25 and Day 30 have fresh public learner checks and a separately labelled public teacher-targeted key. Collect first responses before feedback; a public key does not make a secure exam. Teachers can change fictional inputs if prior access matters.
The two weeks progress from model overtime and allowance layers to mark-up versus margin, forward/return percentage change, a fictional AUD–USD rate, dividend yield and P/E ratios. Every day includes three equivalent-target response routes, distinct optional settings and a next teaching move. Five original A4 SVG/PDF and accessible text/tactile aids plus an offline invented-rate switch can be used with paper, calculator, oral/AAC or typed responses. There is no need to use real financial data or spend money.
The official QCAA General Mathematics 2025 v1.3 syllabus is the authority. See the exact source-page/row and partial-coverage crosswalk, rights ledger, dated source snapshot, desk run-through, verifier and SHA-256 manifest. GM-U1-T1 is our shorthand, not an official QCAA code. This resource does not complete the 14-hour Topic 1 subtopic, Unit 1, formal school assessment or a Year 11 course. No live class or user validation is claimed. Wages, exchange rates, companies, prices and dividends are invented, and no real employment, tax, currency or investment decision follows.
