# C11 · 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

Review the comparison against its question.

## Day

46

## 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

C11

## Materials

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

## Next teaching

If all changes counted as fair, use unrelated toy-travel plan: compare rolling on same mat versus rolling different toys on different ramps. Child chooses which answers a mat question then designs a new sound comparison.

## 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

Name action as the planned change and ask which similarities were only planned.

## Whole original context source and possible worked

C11 fictional costume shop asks whether tapping and rubbing the same lid will give different reports. Same helper/spot and one action each are planned. Before the trials, the helper predicts tapping and rubbing will give different reports, using an earlier supplied tap/rub comparison as the clue. Supplied reports: tap “short”; rub “longer”. Force not measured. Possible: “The described reports differ as predicted. The plan kept object/helper/spot similar; unmeasured force still limits an action-only cause claim.”
