Bounds
All described events are original supplied fiction. No local experiment, child success, measurement, reader hearing ability or annual attainment is supplied.
Child invitation
Build two exact report rows.
Different child try
Child chooses an unrelated everyday job and writes/draws one source/action clue plus one unknown. Do not copy the ordinary worked sentence; keep any actual event distinct.
Materials
Full printed/readable source, blank paper guide and optional exact scribing/AAC; no required device/audio/material purchase.
Next teaching
If rows swap, use unrelated skate-park model notes: “roll toy car—stops by blue line; slide card—stops by red line”. Pair action/result first, then return to sound without borrowing a model answer.
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
Draw source/action/report columns and read each entire supplied row before placing it.
Whole original context source and possible worked
C03 fictional parcel station uses the same tray and observer spot. Row1: helper gently taps tray once; report “short low tap”. Row2: helper rubs tray edge once; report “longer scratchy sound”. Strength was not measured. Possible ordinary response: “These notes give two different descriptions for two actions on the tray. They do not show that action alone caused the difference.”
