## What was checked

- [ACARA, Australian Curriculum Version 9.0 downloads](https://www.australiancurriculum.edu.au/downloads), official workbook downloaded **29 September 2026**. Local file `products/curriculum-studio/research/sources/acara-australian-curriculum-v9-download-2026-09-29.xlsx` has SHA-256 `db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3`. The normalized `products/curriculum-studio/data/frameworks/acara-v9.json` declares the same source hash. The [crosswalk](CURRICULUM-CROSSWALK.md) gives each selected Year 6 or official Years 5 and 6 band code, original workbook row, exact wording and an honest partial-evidence boundary. Source wording is not a SubjectNest learning outcome or state syllabus guarantee.
- [ACARA copyright and terms of use](https://www.australiancurriculum.edu.au/copyright-and-terms-of-use) was checked for attribution, CC BY 4.0 core material and exclusions. © Australian Curriculum, Assessment and Reporting Authority (ACARA) 2010 to present, unless otherwise indicated. The curriculum wording was downloaded from the Australian Curriculum website on 29 September 2026 and was not modified in the crosswalk wording column. SubjectNest adds a day/scope analysis. ACARA does not endorse, sponsor, approve or affiliate with this pack.
- **All case data and arithmetic are original fiction.** Source B's exclusive categories sum `12 + 6 + 6 = 24`; `12/24 = 1/2`, `6/24 = 1/4`, `18/24 = 3/4`, and a hypothetical `8/24 = 1/3`. Source E's `24` factors include 2×12, 3×8 and 4×6; `23` is prime; `25 = 5²`. Check A's `14 + 7 + 7 = 28`, `28 = 4×7`, and `29` is prime. Check B's `16 + 8 + 8 = 32`, giving `1/2`, `1/4` and `3/4`. These are arithmetic truths inside invented records, **not verified real observations**. No real source is cited to support an invented trial.
- The teaching approach and 35-minute timings are original design decisions, not research-tested effectiveness claims. The one-day paper-sign record cannot establish stability, safety, readability to every viewer, accessibility, sustainability, outdoor performance or success at scale. A real supervised classroom mini test, if undertaken, produces **separate** observations under school policy; the invented values are never pooled with it.

## Claims and local holds

This is **ten 35-minute inquiry sessions** to accompany the existing English and mathematics weeks. It does not supply a full weekly HASS, Science, Technologies or Arts allocation, a whole-year course, an achievement-standard decision, a psychometric assessment or a state/territory-approved sequence. One check cannot measure all strands of the codes. The live status of a lesson is “authored and desk-tested”, not classroom-trialled. School educators must review the local jurisdiction's syllabus, timetable, equipment, safeguards and access requirements. No real signage is installed; no children are surveyed, photographed or identified. The pack makes no claims about local Country/Place or First Nations knowledge/language and supplies no translation. Such additions would require appropriate community authority, rights and linguistic review. Science `conduct`/`measure` evidence is conditional on an **actual permitted test**; design making, visual art creation and partner interaction are likewise conditional on observed action.
