Try one little turn.
Prepare: A described 0–1 number line split into four equal gaps.
Invitation: Ask where one-quarter and three-quarters go. Child can give an ordered spoken list rather than draw.
Adult model/check: MODEL 0,1/4,2/4,3/4,1; three gaps from 0 reaches 3/4, one gap remains. Five marks do not make fifths.
Observe and respond: Ask for one useful reason; keep the child's response as actually made. If ticks and gaps confuse, trace two gaps between three marks on a new halves line. No timer or body movement.
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.
