| [ACARA Version 9.0 full curriculum download](https://www.australiancurriculum.edu.au/downloads), accessed 29 September 2026; official XLSX SHA-256 `db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3` | [Verifier](verify_pack.py) checks original workbook bytes, exact Year 5 Mathematics content descriptions, codes and workbook source rows against the pinned local import. [Crosswalk](CURRICULUM-CROSSWALK.md) maps five **partial** opportunities. | Codes do not prove full content descriptions, achievement, state/territory adoption or a mandated week order. Recheck current official and local sources before reissue. ACARA material remains under [its terms](https://www.australiancurriculum.edu.au/copyright-and-terms-of-use). |
| [ACARA Year 5 mathematics work-sample page](https://www.australiancurriculum.edu.au/resources/work-samples/mathematics/year-5/ws03-representing-and-adding-fractions) | Its Year 5 achievement summary describes efficient strategies for larger-number multiplication; used only as a level check. | That sample concerns fractions; no pupil work, annotation or illustration is copied, and this two-week pack does not assess a full standard. |
| [QCAA ACiQ Version 9](https://www.qcaa.qld.edu.au/p-10/aciq/version-9) | Queensland implementation entry for local checking. | Other states/territories use their own current implementation; no nationwide compliance conclusion follows from a national code. |
| [AERO explicit instruction practice guide](https://www.edresearch.edu.au/guides-resources/practice-guides/explicit-instruction-practice-guide-full-publication) | Supports explicit worked examples, small guided steps, deliberate practice and feedback in the lesson design. | The new scripts are SubjectNest choices. AERO did not review, trial or endorse them. |
| Original arithmetic and contexts | Independently recomputed every [30 core learner-card product](teacher/TEACHER-KEY.md), 18 numeric optional extensions, two held-out products, budget differences and bundle-limit comparisons with integer arithmetic. The [verifier](verify_pack.py) rechecks a structured audit list and fresh-answer separation. | All settings are fictional. The arithmetic does not establish an actual sport capacity, travel plan, shop price, environmental benefit, school need or child outcome. The two open-design extensions have no single numeric key; a teacher checks the child's chosen numbers. |
| Original print aids | [Vector source](print/generate_print.py) generated two A4 SVGs and matching one-page PDFs; PDF text extraction and font embedding checked. [Full text/tactile equivalents](print/TEXT-ALTERNATIVES.md) provide all labels and numerical examples. | Local large-print/Braille/AAC and learner testing are pending. DejaVu font subsets retain [separate rights](print/FONT-RIGHTS.md); no external image/worksheet copied. |

A future translation requires a named locale and qualified human review; a First Nations-language adaptation also needs authorisation from the relevant language custodians.

**Human review holds:** experienced Year 5 teacher checks classroom timing and taught prerequisite facts; local curriculum lead checks scope/reporting; accessibility reviewer and learners test print/tactile/AAC formats; any real-world data use requires permission and local protocol. The [run-through](RUN-THROUGH.md) is a desk test, not a classroom trial.
