# Year 9 mathematics · Term 1 Weeks 3–4

Ten original **25-minute lessons** continue the Year 9 opening fortnight's attention to representations, units, domains and model limits. Days 11–15 use numerical integer exponents; Days 16–20 extend laws to variable bases and exponents. This is a **partial teaching sequence for one ACARA description**, not a complete Year 9 subject plan or a claim that learners have met an achievement standard.

## Start here

1. Read the [ten staff lessons](LESSONS.md) and choose the day's [fictional model card](MODEL-CARDS.md).
2. Give learners only the matching [clean Day 11–20 page](LEARNER.md). Each day offers **three genuine routes** to the same maths goal; access can change from task to task and is not a fixed learning-style label.
3. Use the [20 short extras and ten no-purchase home routes](EXTRAS-AND-HOME.md) selectively. They are optional, not homework requirements.
4. Prepare the three [A4 SVG/PDF aids and full text/tactile alternatives](print/TEXT-ALTERNATIVES.md). The [font and artwork rights](print/FONT-RIGHTS.md) are separate.
5. Use the two [fresh Days 15/20 checks](ASSESSMENT.md) as clean learner prompts, then the [teacher worked key/next moves](TEACHER-KEY.md) after collection. Both are publicly accessible in this library, so they are formative rather than secure tests; change a case locally if prior access matters.

## Use and review boundaries

The [pinned Year 9 ACARA crosswalk](CURRICULUM-CROSSWALK.md) records exact description wording, source row and the narrow actions in this pack. [Source and rights](SOURCES-AND-RIGHTS.md) distinguish original content, official wording and the external SI-prefix fact. [Desk run-through](RUN-THROUGH.md) records teacher, learner, accessibility and funder checks, not classroom outcomes. Run `python3 verify_pack.py` to recheck source, arithmetic, links, assets and the [hash receipt](MANIFEST.sha256).

Read aloud, AAC, Braille, tactile cards, typing and directed scribing can carry a learner's mathematics; log the access and any mathematical hint separately. A reading accommodation does not demonstrate independent print reading. The fictional counts do not prove game uptake, public safety, physical feasibility or local syllabus approval. Ask a qualified local educator to map this sequence to their state/territory syllabus and learners before classroom use. No translation or First Nations language/cultural content is asserted; any such edition needs authorised language/community review.
