A question about material for a paper badge · separate next teaching

Complete unrelated fiction: Original unrelated fiction. Broad paper and cloth badge pictures have the same outline, mat, flat start and chosen lifted edge with one helper. Material differs; force is unmeasured. Each is lifted once; no result supplied.

Own invitation: Which two things would be useful matches for a material question?

Teaching: State the question before offering details. Invite the learner to name matches and the intended material difference. Ask whether a planned similar height is an actual measured guarantee; leave all results empty.

Observable meaning: Matches are related to the material question while paper/cloth stays the intended difference, not an automatic fault.

This account is separate from held C-first-2. Offer only the wanted actual next learning opportunity, record the help/actor/exposure, and do not invent an observed response or later improvement.
