Prepare: Paper or a described rectangle; no scissors or printer.
Invitation: Invite two equal parts of one whole, then four. Child may fold, draw, describe or direct your hands. Ask what proves equality.
Adult model/check: MODEL: four equal-width sections at one height; one is 1/4 and three more make the whole. Unequal pieces are not quarters merely because there are four.
Observe and respond: Ask for one useful reason; keep the child's response as actually made. If equality is unclear, compare two differently sized pieces from a new whole. Actual folding is optional and separately observed.
Usual communication, wanted exact scribing, private/untimed work, rest and stopping are welcome. No purchase, photo or upload. A model is not an observation of your home; actual child mathematical choice, helper physical action and any real willing-reader trial are separately named.
