# C19 · 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

Identify one useful information revision.

## Day

50

## 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

C19

## Materials

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

## Next teaching

If polish becomes evidence, use unrelated garden sign drafts: decorated sign missing plant name versus plain sign naming plant/source date. Child chooses the useful information change, then names one next science question.

## 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

Compare actual information changes, without choosing by decoration.

## Whole original context source and possible worked

C19 fictional toy-shop guide draft1 says “best tap”; draft2 says “for our pretend stop cue, the supplied helper described one short tap; reader trial is open”. Possible: “Draft2 adds a named purpose, source clue and limit. It is more bounded; actual reader success is not supplied.”
