Complete held source: Original fiction. A broad paper theatre cue has an existing fold. It begins as a low V at a drawn curtain on a flat mat. A helper presses its edge toward a drawn stage mark. During contact it moves nearer the stage mark and becomes flatter. After release it rests nearer and flatter than its first V. Exact force, complete path, later stability and an uncreased cue result are not supplied. No child operation is described.

Exact own prompt: Show or tell the cue’s before, during-contact and after-release moments.

Descriptive criterion: Preserves all three supplied moments: first low V at curtain; during nearer/flatter; after nearer/flatter at rest. No spontaneous return or later stability is added.

Worked possibility, after own evidence: It starts as a low V at the curtain; it moves nearer and becomes flatter during contact; after release it rests nearer and flatter.

Complete unrelated next account · A low pretend bridge picture

Full source: Original unrelated fiction. An existing-fold broad paper picture begins flat. A helper presses at its fold; it bends during contact and rests as a low V after release. No weight, real crossing or later stability is tested.

Own invitation: Show the three moments without adding a later return.

Teach: Read before/during/after slowly. Ask for a drawing, sign or spoken turn per moment. Revisit after release separately from a later unseen moment.

Observe: Sequence retains flat, bending during, low-V rest after; no real structure safety or spontaneous return is inferred.

Record the first exact evidence before help. A later source requires an actually recorded separate teaching opportunity. Source reasoning does not award an unperformed procedure or observation. Declined/not offered/not elicited/selected relation not shown remain distinct. This is not an official band or an annual grade.
