Target/codes: directly compare two printed lengths with aligned starts, then order familiar parts of a fictional day; AC9MFM01, AC9MFM02. Prepare: P198 equal-scale sheet.
- Notice · 3 min. Point to straight strip M and N. Ask what must line up to compare length fairly; do not call a thicker strip longer.
- Model · 4 min. Align their printed left start marks on the same 100% page or trace them onto equal-scale paper. Show only the first common part.
- Guide · 5 min. Child compares right endpoints; N extends beyond M and is longer on this page. If scale/print changes, reset rather than report a result.
- Independent route · 7 min. Day 198 A/B/C use overlay, same-scale tracing or adult-directed alignment and then order MORNING → LUNCHTIME → AFTERNOON → NIGHT for an invented day.
- Reason check · 4 min. Move strip starts to different positions and ask if that is still a direct fair comparison. Re-align. Ask whether the four named times are a duration measurement; they are sequence labels, not measured elapsed time.
- Exit · 2 min. Child gives a length reason and one adjacent day-part transition. This does not assess capacity, mass or every duration event.
