This original continuation follows Weeks 1–2 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, three flexible same-target learner routes daily, twenty worked context swaps, eight original A4 pictorial SVG/PDF aids with exact text/tactile equivalents, and two fresh public formative checks with a separate public key.
The offline keyboard-accessible copy checker 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 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 only when suitable; otherwise mark AC9TDIFK01 not observed and teach with paper.
The exact ACARA v9 and Queensland Prep crosswalk separates conditional K01 from partial K02/P01. The source/rights ledger, teacher/learner/reviewer desk run, read-only default verifier and SHA receipt 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.
