Goal: compare two new start-together events by observed duration and reject an unsupported staggered-start conclusion. Proposed code: AC9MFM01. Prepare: unseen Assessment setup, Card 120, private record and accessible A/B cues.
- Welcome · 3 min. Explain that the event comparison helps choose the next activity; it does not measure how fast a child works.
- Setup · 4 min. Name two large paper actions and give the agreed cue channel; do not hint which will stop first.
- Fresh observation · 5 min. Start both together, stop A first, continue B, then stop B. Offer an identical replay only when requested/needed and log it.
- Independent reason · 7 min. Child names first stop, continuing action and longer event, then explains using the shared start and observed stop order. Preserve first response.
- Boundary check · 4 min. Present the separate staggered-start case; ask whether stop order alone settles it and how to make a direct comparison. Record any coached revision apart.
- Close · 2 min. Choose one next move from Assessment: notice continued action, equal-start rule, ignore amount/distance, or access route. One check does not certify all of AC9MFM01.
The Week 23 integrated story/time guide and Week 24 feelings/help guide offer extra practice. Preserve each subject's first independent response before group rehearsal or feedback.
