Complete original fictional display-ledge diagram account. Drawn labelled bases M and N use a printed centimetre scale from zero with equal1cm intervals. M spans0–3cm; N spans0–5cm. Those are supplied diagram readings, not dimensions of real rocks or the child’s own ruler measurements. The diagram records no prior prediction. Its display-reader job is to compare these two drawn bases accurately. A separate new plain-paper measuring plan could ask which chosen paper base is longer, use a familiar centimetre ruler with zero aligned and the same base direction, and keep an actual prediction before its own measurement. No new paper result is supplied.Optional separate full source reference
