# C15 · 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

Keep a prediction separate from a missing result.

## Day

48

## 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

C15

## Materials

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

## Next teaching

If prediction becomes result, use an unrelated paper-bridge story predicting two toy figures will fit but no trial held. Put prediction before blank trial area, then child reconstructs a fresh cover record.

## 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

Place prediction before a genuinely empty covered-result space.

## Whole original context source and possible worked

C15 fictional reading-desk team predicts a cloth may make a tap seem softer. Uncovered tray/tap is reported “soft”; cloth-cover tray/tap has no result supplied. Possible: “The prediction is untested in these notes. We need the covered report before comparing.”
