Job: repeat a useful actual comparison and represent the available evidence. Ready: chosen locally approved setup and optional blank record-a-try mat. Say: “What did we actually notice?”
- 0–3: Choose an available question/plan from ordinary work or begin a fresh one. Never invent a Day25 result. Decide whether actual apparatus is wanted and which observation/quantity matters.
- 3–8: Offer a short actual baseline/changed look before table discussion. Repeat a part if that will answer the question. Name operators/observers; do not call an adult trial independent child equipment work.
- 8–12: Choose a fair description/measurement for the available edges: qualitative size/clarity/position, or an appropriate instrument/unit and sensible precision. Let the learner decide how to represent it—table, labelled drawing, spoken/signed record or directed marks. Adult-read measurements retain their source.
- 12–20: Record the available actual observations, repeat only when useful, and retain missing/unclear entries. Add model predictions in a separately named area if wanted; do not fill actual-result rows with them. A diagram-only route represents model information and proposes a future record.
- 20–25: Ask which record helps the child's job/question. Notice an actual representation choice and supported relation, or an honest gap. Next: a different question about the screen. No minimum number of trials or full table gate.
