Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Target: Compare B's far and near count-2 routes while holding counts 1, 3 and 4 constant.
Prepare:B, path grid, two colour-independent marker rows.
Launch · 2 min. Offer a fictional guide needing to direct attention towards either the far side or near edge; these are imagined spaces.
Model · 4 min. Build H–F–R–H above H–N–R–H. Cover the matching counts. Name count 2 as the only different location.
Guided looking · 5 min. Ask what a viewer can see at 2 and why a far-side purpose could favour F. Acknowledge more than one defensible answer with evidence.
Practice route · 7 min. Learner directs, annotates or opts in to a comfortable direction gesture. They choose one route for a stated audience/context and name the changed count.
Audit · 4 min. Count both four-beat versions, ask whether the claim predicts every viewer, and ensure no floor travel was demanded.
Exit · 3 min. Save two route strips and one because-sentence; preview timing with locations unchanged.
