Complete source: Original fiction. A broad paper piece with an existing fold starts flat on the mat. An adult gently presses along that fold; while pressing, its two sides rise into a bend. After release it remains V-shaped at rest. The maker wants a small paper picture stand. No later stability check, reader reply or uncreased-piece result is given. The star and square drawn on the mat keep the viewpoint fixed.
Own invitation: Describe the shape at each supplied moment and a useful further question.
Worked possibility and a different next teaching invitation
**Source-supported possibility:** Flat before, bent during the supplied pressing action, V-shaped after release. This piece’s existing fold/history is part of the source. A later rest or different-history question is useful, but no stability guarantee or all-paper claim follows. An adult acted in this fiction.
**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 C12’s cloth moments including an extra arranging act. Invite the child to keep all moments in order and describe what happened after release versus after new contact. No required physical folding or shape vocabulary length.
