Target/codes: Evaluate a design against actual evidence or a named unknown and propose a specific change; AC9TDEFP01.
- Welcome · 3 min. A card moving is useful information about one setup, not a wrong child answer.
- Read source · 4 min. Reopen the child's own Day 47 record. If there was no trial, use the blank revision mat and keep result NOT TRIED.
- Model · 5 min. Say explicitly as a hypothetical: “If a card crossed the line, I might draw a wider box or place it farther from the boundary; then I would check again.” A thicker printed line is not proven to stop a physical card.
- Child response · 7 min. Children propose one change to zone width, label position, border or card placement. Connect the change to an observed problem or untested question. With fresh local approval, a second real try gets a new record; otherwise remain a proposal.
- Check/respond · 4 min. Record evidence/unknown → proposed change → next check. If only decoration changes, ask how it serves the stated viewer/source purpose.
- Exit · 2 min. “I saw/was told , so I would ,” or “I still need to find out ___.”
