The opening fortnight codes below are from content_description records at exactly Year 8 level in the local normalized official ACARA Australian Curriculum Version 9.0 workbook, retrieved 29 September 2026. Workbook SHA-256: db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3. Weeks 3–4 also use Year 8 and official Years 7 and 8 band rows. Their exact wording, row numbers and taught limits are in the English, mathematics, integrated inquiry and five-area crosswalks. Exact description hashes appear in manifest.json. Recheck the official version history and applicable state or territory syllabus before classroom use. A code is a proposed link to part of a description, not a whole-content or achievement-standard claim.

The ACARA help says education authorities or schools determine teaching time. These 25/35-minute sessions and optional 12-minute blocks do not establish a mandated timetable.

Each later pack has a separate English rights ledger, maths source record, integrated rights ledger or five-area source ledger.

Holds before “classroom reviewed”
- A Year 8 educator and curriculum leader check the local syllabus, timing, model assumptions, mathematical progression and whether the source tasks suit their class. State and territory overlays remain unresolved.
- Learners and support staff try the text alternatives, screen reader/braille routes, large print, tactile graph, AAC, writing and private spoken response modes as relevant. The PDFs are print aids, not tagged accessible PDFs; the plain-text files are the screen-reader route until user testing says otherwise.
- The school checks privacy and consent before any real survey or recording. This pack uses fictional data so no learner must reveal household finance, travel mode, address or disability.
- Future First Nations histories, perspectives, Country/Place or languages need relevant community authority, source verification, consent and attribution. No such content or translation is invented here.
- A real classroom trial records missed steps, misunderstood prompts, time overruns and revisions. The author's dry run cannot replace one.
Automated checking verifies codes/level, links, file hashes, timing arithmetic, key calculations and print structure. It cannot establish classroom impact or full-year curriculum coverage.
