C19 · Keeping a useful rule

Complete source: Original fiction. One adult makes two short intended-gentle pushes of the same broad paper piece from the same drawn start toward the same broad goal on the same mat. Both recorded resting positions are wholly inside the goal after resets. The maker keeps the “one small push toward the goal” rule for this job. Exact force and a future different-player attempt are not supplied.

Own invitation: Why can keeping the rule be sensible here, and what remains open?

Worked possibility and a different next teaching invitation

Source-supported possibility: Two supplied fits support the maker’s limited keep choice for this job. A change is not compulsory, more distance is not automatically better and another player/surface/attempt is open. It does not establish exact force, permanent reliability or a child’s actual motor performance.

Unknown/limits: Keep every missing force, path, future attempt, actual child operation and player response within this source’s stated limits. A complete fictional record is source evidence, not performed-investigation evidence.

Full next teaching: Use C05’s purpose-dependent gentler/firmer comparison. Ask which result serves that source’s job and one bounded next question. Listen for purpose rather than compulsory change or universal “stronger is best”.
