## H09 · A rule can need a boundary word

**Complete source:** Original fiction. A broad paper piece rests touching a drawn goal line. One reader says it touches the boundary; another says it is not wholly inside. The written rule only says “reach the goal”. It does not state whether touching counts.

**Own invitation:** Can both readers’ descriptions fit? What question would help with the rule?

**Wanted practical offer:** A broad drawing and an unmoving paper piece are enough. The child can invent a wanted line rule, keep it private and decide whether a later person should be asked. No winner is needed.

**Complete alternative and access:** Read each statement separately. Offer the complete source again and neutral “touches”, “inside” pictures or usual AAC without indicating a preferred rule.

**Notice and next:** Do not turn a missing rule into a wrong observation or an argument to win. Different player preferences remain unsupplied.
