Checked 29 September 2026. This is a dated review, not a live update feed. Curriculum wording is reproduced only in the exact code crosswalk with attribution. The lesson prose, thirty learner routes, two unseen checks, fictional number contexts, mathematical diagrams and text alternatives are newly authored. No third-party illustration, worksheet, song, logo, photo, video or First Nations cultural material is bundled.
| Source or asset | Verification and use | Boundary |
|---|---|---|
| ACARA Version 9 downloads and official workbook | Pinned local import products/curriculum-studio/data/frameworks/acara-v9.json, source SHA-256 db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3. The verifier checks exact Year 4 Mathematics text and official source rows AC9M4N01 17541 and AC9M4N03 17553. |
Two partial content-description links, not all Year 4 standards or a current state/territory plan. Refresh before a later edition. |
| QCAA ACiQ Version 9 Mathematics | Queensland implementation entry point checked. It provides Year 4 standards/content and planning resources. | Each school must verify its current local syllabus, calendar and agreed teaching sequence. This pack does not claim QCAA assessment approval. |
| ACARA copyright and terms | ACARA curriculum text is attributed under its general CC BY 4.0 terms with plain-text modification. | ACARA excluded material, including logos, photos, videos and support resources, is not reused. No ACARA endorsement or affiliation. ICIP boundaries are respected: no community-held content is invented. |
| Decimal/fraction arithmetic | Independently recalculated with exact rational values in the verifier, then checked against the staff key and learner prompts. Examples include 0.30 + 0.06 = 0.36, 0.70 − 0.68 = 0.02, 2/5 = 4/10 = 40/100, 1/2 − 2/5 = 1/10, and 3/4 − 3/5 = 3/20 = 0.15. |
Exact equalities assume the same whole and equal parts. A decimal number-line scale must have equal gaps. Fictional values do not establish real measurements. |
| Original decimal-line and equal-whole aids | Generated from original drawing source, visually inspected. Each PDF is one A4 page with selectable text. SVGs have title/description; the complete text/tactile alternatives supply every prompt and spatial relationship. The equivalence sheet uses five physically equal-sized square wholes, correcting an initial draft with mismatched bar/grid footprints. | PDF tagging, real printer devices and human screen-reader/tactile co-design are pending. The blank aids do not contain assessment answers. |
| DejaVu Sans PDF font subset | Font licence and full copyright notice accompany the embedded subsets. | Font rights remain separate from original lesson CC BY 4.0 material and Apache-2.0 code. No standalone font binary is bundled. |

Review state: The teacher/learner/home/funder desk run-through tests representative tasks and artifacts, not classroom learning.

An automatic link, code, arithmetic or print pass cannot establish student outcomes or year-long coverage.
