# Foundation / Queensland Prep Digital Technologies · Term 1 Weeks 3–4

This original continuation follows [Weeks 1–2](../weeks-01-02/README.md) with a new task: read an invented four-entry picture source, represent the same data with **physical objects, pictures and symbols**, find a mismatch in a copy, and use an actual approved digital system for a clear purpose if available. It contains ten optional [25-minute Days 11–20 teacher scripts](LESSONS.md), [three flexible same-target learner routes daily](LEARNER-CARDS.md), [twenty worked context swaps](PRACTICE-SWAPS.md), eight original [A4 pictorial SVG/PDF aids with exact text/tactile equivalents](print/TEXT-ALTERNATIVES.md), and two [fresh public formative checks](STUDENT-CHECKS.md) with a [separate public key](teacher/KEY-AND-NEXT.md).

The [offline keyboard-accessible copy checker](interactive/copy-checker.html) lets a child switch the original prop source between picture and symbol views, change a mistaken symbol copy and receive position-specific feedback. Its [full paper route](interactive/PAPER-EQUIVALENT.md) reaches the same representation/correction target without a device. Both routes use fictional data and no accounts or personal input. A **screen drawing, screenshot, paper card or adult-operated device cannot show that a child explored a running digital system**. Use the [school-approved actual-device evidence gate](DEVICE-GATE.md) only when suitable; otherwise mark AC9TDIFK01 **not observed** and teach with paper.

The [exact ACARA v9 and Queensland Prep crosswalk](CURRICULUM-CROSSWALK.md) separates conditional K01 from partial K02/P01. The [source/rights ledger](SOURCE-AND-RIGHTS.md), [teacher/learner/reviewer desk run](RUN-THROUGH.md), [read-only default verifier](verify_pack.py) and [SHA receipt](manifest.json) show what was checked. No child name, image, voice, address, help route, account or actual data is requested or stored. Checks are fresh relative to lessons but public, **not secure exams**. This is not full Foundation Digital Technologies, a QCAA-endorsed unit or a classroom-effect claim.
