Bounds
All described events are original supplied fiction. No local experiment, child success, measurement, reader hearing ability or annual attainment is supplied.
Child invitation
Make a guide for a no-sound purpose.
Different child try
Offer a new not-yet-tried pretend job chosen by the child. Child names which information would be needed before a result claim; that new result remains genuinely open.
Materials
Full printed/readable source, blank paper guide and optional exact scribing/AAC; no required device/audio/material purchase.
Next teaching
If “best everywhere” persists, use unrelated library opening-time cards where one branch has a supplied time and another none. Make a branch-bounded advice sentence, then child refines a different sound guide.
Observe
Listen/read/point for the exact source-qualified distinction named in the invitation; record authorship, support and actual/supplied/model mode. A selected label without its meaning does not prove the whole understanding.
Role
ordinary teaching/worked model; never independent held assessment evidence
Teacher moves
Allow no-sound recommendation justified by the stated quiet job, not by an invented acoustic reading.
Whole original context source and possible worked
C18 fictional kitchen role play wants no sound while another group reads. No sound reports provided. Possible: “A printed turn card fits this quiet job; a future reader can tell us if its instruction is clear.” No noise-law/local acoustic fact claimed.
