# D-first-3 · teacher component

**Complete held source:** Original fiction. A broad paper ticket rests touching a drawn station-goal boundary and is not wholly inside it. The written rule says “reach the station” and does not say whether boundary touching counts. A child-character dictates, “Could we say whether touching counts before the next turn?” A helper writes these exact words. No next turn or other player’s reply is supplied.

**Exact own prompt:** Give your own short useful message or question for a possible player. Leave their choice or reply open.

**Descriptive criterion:** Communicates source-relevant boundary-rule uncertainty with a plausible own message/question; no imagined reply, compulsory peer, writing or correct universal rule.

**Worked possibility, after own evidence:** “Do you want touching to count in this game?” is useful. “The rule does not say yet; shall we decide?” is another. The player’s own answer is absent.

## Complete unrelated next account · A player chooses whether to join

**Full source:** Original unrelated fiction. A maker has a paper parking-game sketch and asks a fictional player whether they want to try, change or leave it. No reply or trial is provided.

**Own invitation:** Give your own kind useful invitation without filling their answer.

**Teach:** Offer a private spoken/sign/AAC invitation or large picture choice. Let the learner choose wording rather than use a supplied reply. Explicitly leave a player-answer space blank, with no diagnosis or preference assumption.

**Observe:** Own invitation supports choice and preserves absent reply; participation and public speaking are not required.

Record the first exact evidence before help. A later source requires an actually recorded separate teaching opportunity. Source reasoning does not award an unperformed procedure or observation. Declined/not offered/not elicited/selected relation not shown remain distinct. This is not an official band or an annual grade.
