# Foundation / Prep mathematics · Term 4 Weeks 33–34

**Development draft · 29 September 2026.** Ten 25-minute lessons (Days 161–170) continue the [Foundation year sequence](../../../year-sequence.md). Week 33 asks a given question of fictional observation drawings, sorts the pictures by a feature actually shown, then counts and compares the groups. Week 34 compares length, capacity and mass **directly** while planning a pretend toy shelter. These are mathematics lessons; a story about living things or design does not establish Science or Technologies outcomes.

Start with [timed teacher lessons](LESSONS.md), the matching [clean learner cards](LEARNER-CARDS.md) and [exact materials](MATERIALS.md). Every day offers three switchable same-target response routes and [two optional worked context swaps](PRACTICE-SWAPS.md). [Fresh Day 165 and 170 checks](STUDENT-CHECKS.md) have a separate [public teacher-targeted key](teacher/KEY-AND-NEXT.md). Both checks and keys are accessible by URL: collect a first response before feedback, and replace a case if prior access matters. These are **not secure exams**.

Use large, supervised paper cards and school-approved plastic vessels. For water transfer and mass comparison, an adult handles the equipment at the child's direction; there is a dry paper/text alternative for preparation, but the evidence for a *direct* comparison needs the actual objects and observed action. Never treat a pictured larger cup or parcel as proof of capacity or mass. Preflight the actual cups and pan balance; if the expected relation fails, replace the materials before a child is assessed. No small loose pieces, real species claims, personal data, photographs, purchases or internet are required.

Original A4 [sort mat](print/feature-sort-mat.pdf), [count board](print/count-compare-board.pdf), [align-ends mat and practice strips](print/align-ends-mat.pdf), [transfer station card](print/transfer-station.pdf), [balance observation card](print/balance-observation.pdf) and [teacher-held check preparation](print/teacher-held-checks.pdf) each have SVG, selectable-text PDF and [full text/tactile alternative](print/TEXT-ALTERNATIVES.md). Keep the last sheet off practice tables. The [crosswalk](CURRICULUM-CROSSWALK.md), [source and rights ledger](SOURCE-AND-RIGHTS.md), [desk run-through](RUN-THROUGH.md) and [hash verifier](verify_pack.py) state what was checked and what remains for local educator review.
