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 preserves rows and unknown count state.

Ordinary possible model

The table has one count and one missing count, with different produce labels.

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.
• Read complete market rows; model one pairing. Guide pencil count, then child labels unopened envelope without guessing.
• 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.

Title

Market-table record integrity

Whole unrelated teaching account

A fictional market tally has apples three and lemons no tally supplied; unknown lemons must not become zero.
