Target/codes: Compare two proposed materials for a named user's cue, without inventing properties; AC9TDEFK01 and AC9TDEFP01.
- Welcome · 3 min. Revisit the willing user's choice: a gentle cue, a visible cue or no sound.
- Notice source · 4 min. Read BROAD CARD and CLEAN SOFT CLOTH plus the two-purpose brief. Both materials are large clean proposals; suitability is unknown.
- Model · 5 min. “I could propose card because I can draw a large visible start mark on it. I would still need to inspect approved real card and ask the user.” Distinguish a design reason from an observed sound or feel.
- Child design talk · 7 min. Child gives a possible use and a question for each candidate, then chooses one to explore for their stated user. Let a child say “neither until the adult checks” with a purpose-linked explanation. An adult may describe actual school-approved materials; note that source explicitly.
- Check/respond · 4 min. Record both candidate questions and the provisional choice. If “the cloth will always be soft enough” appears, ask which person's comfort, exact cloth and approval still need checking.
- Exit · 2 min. “I would ask ___ before choosing ___.”
