Checked 29 September 2026 against the official QCAA General Mathematics page and General Mathematics 2025 v1.3 General senior syllabus, published January 2026. The page says the syllabus applies to students completing in 2026 or later. source-snapshot.json records its identity and page references. This is a Queensland senior syllabus, not an ACARA Version 9 P–10 year-code mapping. GM-U1-T1 is local SubjectNest shorthand, not an official QCAA code.
QCAA places Unit 1: Money, measurement, algebra and linear equations at PDF p. 16 / printed p. 14, then Topic 1: Consumer arithmetic and the subtopic Applications of rates, percentages and use of spreadsheets (14 hours) at PDF p. 17 / printed p. 15. A unit has 55 notional hours including assessment. The first three SubjectNest fortnights each contain ten 25-minute model periods, totalling 750 minutes = 12 hours 30 minutes. Even that planned duration is less than the 14-hour subtopic; quantity alone would not prove coverage or learning. Schools determine actual sequencing and delivery within syllabus requirements. Unit 1 Topics 2–5 and Unit 2 are separate future work.
Printed page 15 subject-matter bullet map
The bullet numbers below reflect their order on QCAA printed p. 15. This is an independent paraphrase, not QCAA wording or an exhaustive account of each expectation. Consult the official source before teaching. A prompt or model touches only the named part; a learner response is needed to judge understanding.
| QCAA row | Official subject-matter focus, paraphrased | This fortnight's evidence | Limit and remaining work |
|---|---|---|---|
| Printed p. 15 bullet 1 | Rates and percentages. | All calculation days label a rate or percentage base and unit. | A few invented examples do not establish fluent mastery. |
| Printed p. 15 bullet 2 | Wages by period or hourly rate, including overtime, allowances, commission and piecework. | Days 21–22 model stipulated additional-hour rates and a once-only allowance; Check A transfers both. | These multipliers and allowances are not Australian awards or entitlements. Period conversion, piecework and commission were in Weeks 3–4. Actual legal pay and deductions remain outside this pack. |
| Printed p. 15 bullet 3 | Government allowance/pension income-support payment calculations. | None. | Unaddressed. Do not replace current eligibility and rates with invented claims; any future real-value lesson needs current official sourcing and school review. |
| Printed p. 15 bullet 4 | A budget for a given income with fixed and discretionary spending. | No new budget lesson here. | Weeks 3–4 offered fictional budget models, not a personal real-world budget. |
| Printed p. 15 bullet 5 | Unit-cost comparisons. | No new unit-cost lesson here. | The opening pack addressed a case; this fortnight cannot stand in for that evidence. |
| Printed p. 15 bullet 6 | Percentage increase/decrease and applications such as mark-up, profit/loss, GST and simple interest. | Days 23–24 compare cost-based mark-up with price-based gross margin; Day 26 reverses a percentage change; Check A transfers base choice. | Margin is a related comparison, not a separate syllabus row. The invented figures are not actual inflation, tax or net-profit data. Other percentage contexts require further examples and assessment. |
| Printed p. 15 bullet 7 | Conversion between Australian dollars and foreign currency. | Day 27/Card M and Check B use AUD and USD with stipulated fictional rates; the offline file lets learners vary a model rate. | No current quote, exchange date, spread, fee, provider or real transaction is established. Source a dated real rate separately if a lesson requires actual market data. |
| Printed p. 15 bullet 8 and formula lines | Share dividend/yield calculations and P/E comparison. | Days 28–29/Card N and Check B compute annual dividend dollars, dividend yield and two P/E ratios. | All companies and figures are fictional. A dividend and ratio do not predict a return, value a company or recommend a purchase. |
| Printed p. 15 bullet 9 | Spreadsheet display for repeated computations. | Day 27 supplies an optional offline rate-switch workbook with two formula rows and a paper equivalent. | The file being present does not prove any learner used or audited it. Observe and record actual spreadsheet action separately if targeting this bullet. |
QCAA lists Unit 1 objectives on printed p. 14, including using/communicating mathematics, evaluating reasonableness and justifying a decision. The labelled checks and limitation statements create limited opportunities to see those behaviours. They are not a full objective-by-objective assessment. The syllabus's printed p. 5 gives Units 1–2 school assessment requirements; our Day 25 and 30 checks are public formative practice, not those formal instruments or secure exams. Their public worked key requires first-work collection before feedback and new locally authored variants when prior access matters.

QCAA subject page identified v1.3. This document paraphrases, and its claim of coverage is independent. |
| Wage multipliers, allowance, prices, percentage changes, exchange factors, dividend and earnings/share | Original invented classroom assumptions in this pack. They are neither current rates nor observed data. Arithmetic is independently verified locally. |
| Real-world pay, foreign exchange, company valuation, suitability | No claim made; the pack names omitted conditions. Teachers must consult current authoritative material before any real-world treatment. |
