# Year 8 mathematics · Term 1 Weeks 3–4 · Days 11–20

**Ten authored, 25-minute daily lessons.** Week 3 continues the [opening Year 8 algebra](../../../term-1/weeks-01-02/mathematics/LESSONS.md) through distribution, like terms, factorisation and rearranging a simple linear model. Week 4 solves, graphs and verifies linear equations and one-variable inequalities. This follows the [Year 8 planning map](../../../year-sequence.md); that map's later weeks remain plans until authored. This is a **partial** sequence, not a whole-year or whole-day provision.

## Use in class

1. Read the [ten teacher scripts](LESSONS.md) and [fictional material cards/access notes](MATERIALS.md). Ordinary lessons are **2 + 5 + 6 + 6 + 4 + 2 = 25 minutes**; the two check days use **2 + 5 + 3 + 10 + 3 + 2 = 25**.
2. Give [the learner page](LEARNER.md), then one [A/B/C route](DAILY-CHOICES.md) each day. All 30 routes aim at the same mathematical construct, with different representations and examples. [Ten optional extras](DAILY-EXTRAS.md) extend practice without a printer or device.
3. Choose the original [expression grouping board](print/expression-tiles.pdf), [balance/rearrange mat](print/balance-rearrange.pdf) or [graph/boundary board](print/line-and-boundary.pdf). Use the [complete text and tactile equivalents](print/TEXT-ALTERNATIVES.md) where preferred.
4. Use the Day15/20 [fresh learner checks](STUDENT-CHECKS.md) after the corresponding lessons. The [teacher answer and next-move key](teacher/ANSWER-AND-NEXT.md) gives all worked answers. Both files are publicly accessible in this library, so these are formative prompts, not secure tests. Save first responses before feedback; change the case locally if prior access matters.
5. Review the [exact ACARA v9 code/row crosswalk](CURRICULUM-CROSSWALK.md), [source/rights record](SOURCES-AND-REVIEW.md) and [teacher/learner/funder desk test](RUN-THROUGH.md). Adjust the local timetable and adopted state/territory sequence with a teacher, while keeping the mathematical target and fresh-check integrity.

**Verification:** `python verify_pack.py` is read-only and checks exact pinned curriculum wording, day counts/timing, 30 routes, 10 extras, held-out separation, arithmetic, local links, A4/searchable PDF aids and the [hash ledger](MANIFEST.sha256). Run `python print/generate_print.py --write` only when intentionally regenerating aids; refresh crosswalk and hashes with `python verify_pack.py --write-crosswalk --write-manifest` after edits.

All model prices, tokens, cards, batches and points are fictional. No actual purchase, family data or classmate characteristics are needed. There has been **no classroom pilot, learner impact measurement, formal accessibility user test or state/territory approval**. The selected Year 8 v9 descriptions are touched in part only; see limits in the crosswalk.
