# C09 · 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

Count records without counting an unknown as silence.

## Day

45

## 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

C09

## Materials

Full printed/readable source, blank paper guide and optional exact scribing/AAC; no required device/audio/material purchase.

## Next teaching

If missing means zero, use an unrelated seed-packet story: two packets have counted seeds, third is unopened. Ask whether unopened means empty, then return to the missing sound report.

## 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

Make one token mean one event row, including the not-recorded report row.

## Whole original context source and possible worked

C09 fictional makers-fair log: tray/tap—“short soft”, paper/rub—“scratchy”, lid/tap—no sound report supplied. Possible table has three rows and an unknown label on the third; two described reports and one unrecorded report, not “two sounding objects and one silent object”.
