# N04 · Toy-car mat comparison

## Child invitation

Suggest one change and one similarity for a useful toy-travel question, then ask a further question with guidance.

## Guided different context

Lay two flat paper textures with a toy/card approved by adult. Plan a new question about travel without slopes, and leave any result open unless gently tried.

## Mode opportunity

This is supported teaching after review. Actual performing, reasoning about supplied stories and model construction are recorded separately. New-context transfer is a small observed step, not annual mastery or a new official grade.

## Next decision

If the named distinction is still unclear, return to two source-labelled cards in this unrelated context and one prompt at a time. If clear, offer a different job/source after further learning; do not retry this held case with the staff model rehearsed.

## Observable next evidence

Child connects comparison choices to the question and recognises an unmeasured factor.

## Ordinary possible model

Mat was the planned change; unmeasured push limits a mat-only cause claim.

## Teacher preparation

Full account/model and a separate blank child page; cards or paper drawings as named in the guided context. Offer pointing/AAC/exact scribing and quiet helper operation. No source collection or public publication is required.

## Teacher sequence

- Read the complete new account and ask which event/reference is actually supplied before showing its ordinary model.
- Show the car source in two panels. Ask what changed, what was only planned similar and what was not measured. Child directs a new safe plan without being told the result.
- Guide the different new context above using an open question. After child chooses, pause so they can author/select/draw their own evidence distinction; the model answer stays a teaching example, never inserted into their own work.
- Invite the child to explain one exact clue and one limit in the new task. Keep actual events, supplied stories and unperformed plans labelled. Use the observable check below to choose whether to revisit this meaning or offer a genuinely fresh task later.

## Whole unrelated teaching account

A fictional car desk compares the same toy rolled from a blue line on paper then cloth; stopping places differ. Release push was not measured.
