Next teaching D-later-3

Whole source

Original next full revision pair: First guide: “Use that page.” Revised guide: “Open Picture parts on page 1.” Destination page 1 says: The pretend model has a square body and round wheel marks. No reader has tried the guide.

Invitation

Explain the change and what a future response could check.

Three complete moves

Read both versions and the complete destination.

Ask what the new pointer supplies and plan one relevant reader-understanding question without claiming its answer.

Cover the model. Reread the whole new source in the usual route, invite a fresh small contribution, and preserve the exact own words and actual help.

Staff possible reasoning

The revision gives a heading and page with a full matching destination; whether a particular reader finds it remains unreported.

Notice

A text change and a still-open practical outcome are distinguished.

Original different teaching source; not performed teaching or learner evidence

Record actual teaching and help before a later offer. Model exposure is not erased by covering the model.
