C16 · Same resting count, strength unknown
Complete source: Original fiction. Two intended action labels, gentler and firmer-but-still-gentle, use the same broad card, start, direction, mat, adult and equal drawn-space unit. Each supplied resting finish is two spaces from the start. No force measurement or whole travelled path is recorded. The question is whether these finishes establish exactly equal strength.
Own invitation: What is equal in the record and what is still unmeasured?
Worked possibility and a different next teaching invitation
Source-supported possibility: The stated resting displacement/count and unit agree. The intended labels differ, but actual force strength is unmeasured; equal finishes do not prove exactly equal force. No need to invent a setup fault or say a supplied result is wrong.
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 C07’s overlapping four results and ask the child to keep the two-space overlap. Record whether actual source results and intended action labels remain distinct; no average, motor competition or stronger push needed.
