# C03 · Complete ordinary teaching context

## 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.

## Day

42

## 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.

## Id

C03

## 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.”
