Day 17 — Two people can notice different effectsYear 3 HASS · T1 W3–4 · Teacher · Teacher / Day 17

Purpose/codes: Identify attributed perspectives and analyse what they support; K01/S04/S05/S07. Prepare: O17 two invented voices plus a shared event note. Child start: “What matters to each speaker? They don't have to agree.”

1. Invite: O17 INVENTED ferry-room note: a waiting table was moved from the door to the wall in 2020. Inez says “I can get past the door more easily”; Hal says “I preferred the table near the door so I noticed the timetable.” Both are supplied fictional reports, not today's user research.
2. Model: Place each person's stated effect beside their own name. Explain one change can have different effects; neither voice speaks for all visitors. Do not infer a diagnosis or actual capacity from a role.
3. Guide: Children make a two-view comparison. A third unnamed visitor's view is unknown, not automatically a compromise. Compare an attributed experience statement with a material/location fact.
4. Choose: Use one mechanism. Children can analyse without acting as a speaker; no compulsory public debate.
5. Check: Child names each priority/effect, one source-grounded common event and a missing view/question.
6. Next: If views swap, use unrelated fictional tool-shelf notes from Bea who values visible labels and Kit who values quiet instructions. Match exact words to each name, then offer new speakers. If everyone is assumed, limit “all” to the actual source scope.

Routes: (a) Two-voice soundless comic: speech/signed/AAC bubbles with names, read privately; no recording. (b) Perspective tiles: sort source phrases beside Inez/Hal and place an unknown card for an unasked person. (c) Host's fair summary: dictate a two-sentence introduction that preserves both views and the shared change without taking over their voices.

Observation: Accurate attribution and no universal claim; not persuasion polish. C-first can follow this teaching plus Day 18 source-limit instruction, rather than being offered early.
