H09 · A rule can need a boundary word

Source review complete · local suitability still needs review.

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.
