C07 · The labels overlap
Complete source: Original fiction. One adult uses the same broad paper piece, flat mat, start and direction. Intended-gentler attempts end one and two equal drawn spaces from the start. Intended-firmer still-gentle attempts end two and three of those same spaces from the start. All four attempts reset. The force is unmeasured; no later result or exact whole-path length is supplied.
Own invitation: What relation and variation can you show without claiming every firmer-labelled push went farther?
Worked possibility and a different next teaching invitation
Source-supported possibility: Gentler results are one/two; firmer are two/three, so the sets overlap at two. These few intended-firmer results are shifted toward farther resting positions, but not every one exceeds every gentler result. Both labels vary and no force number or universal law follows.
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 C16’s equal finishes with two intended labels. Read the unchanged start/unit/finish givens; ask what they establish about result and what they do not measure about force. Listen for the distinction, not arithmetic or a required fault.
