# Year 7 mathematics · Term 1, Weeks 3–4 · Days 11–20

**Ten ready-to-run 25-minute lessons.** Week 3 revisits rational forms and estimates, then extends fraction/decimal/percentage operations to multiplication and grouping division. Week 4 builds prime factorisation with exponent notation and connects perfect squares to their positive roots. This continues the [authored Year 7 opening fortnight](../../../term-1/weeks-01-02/README.md) and the [40-week planning route](../../../year-sequence.md). It is a **partial** Year 7 maths sequence, not a complete year, whole school day, state/territory endorsement or achievement-standard judgement.

## Take it to class

1. Prepare [teacher scripts](LESSONS.md), [materials/access routes](MATERIALS.md), and keep the [private staff answer/next-move key](teacher/ANSWER-AND-NEXT.md) off learner displays.
2. Give the [clean learner page](LEARNER.md), one of [three meaningful daily practice routes](DAILY-CHOICES.md), and the right original A4 aid: [operation/check mat](print/operation-check.pdf), [prime-factor tree](print/prime-factor-tree.pdf), or [square/root link](print/square-root-link.pdf). The [complete text/tactile alternatives](print/TEXT-ALTERNATIVES.md) carry every label and layout.
3. Each ordinary lesson uses **2 + 5 + 6 + 6 + 4 + 2 = 25 minutes** for launch, model, guide, practice, exit and evidence note. The [ten optional extras](DAILY-EXTRAS.md) extend a local timetable or home practice without a device or purchase.
4. On **Days 15 and 20**, open the [fresh checks](STUDENT-CHECKS.md) only then. The six-minute route and four-minute exit become a ten-minute check. D15/D20 routes are **later practice**; save first responses before feedback. Record neutral access support separately from a mathematical hint.
5. Use the [staff key](teacher/ANSWER-AND-NEXT.md) to choose one next teaching move from exact work. Speech, sign/AAC, pointing, typing, drawing, tactile pieces and learner-directed transcription can show mathematical reasoning.

All contexts and numbers are invented teaching examples. No real price, measurement, group outcome, local knowledge, learner identity or family budget is represented. The [exact ACARA v9 crosswalk](CURRICULUM-CROSSWALK.md) pins Year 7 content rows with taught limits. [Sources and rights](SOURCES-AND-REVIEW.md), a [teacher/learner/funder desk run](RUN-THROUGH.md), [hashes](MANIFEST.sha256) and [read-only verifier](verify_pack.py) make the pack inspectable. Run `python verify_pack.py` from this folder.

**Evidence boundary:** internal desk simulation and automated checks have been completed. There has been **no classroom pilot, learner outcome study, formal accessibility user test, validated assessment or jurisdiction sign-off**. Check the adopted state/territory curriculum and class access needs before use.
