# Check a budget result


## Access

Read or sign the exact source and prompts neutrally, enlarge them, or scribe the learner’s chosen words. A figure, operation, regrouping, equation role or check supplied by an adult is mathematical help and is recorded as such. Show, draw, type, sign or use usual communication. One component can be enough; pause/pass/finish are choices. Four own spaces are genuinely empty. Models, criteria and next lessons stay on separate staff pages.

## Complete different guided source

A pretend AUD plan costs $148 and $247, budget $400.

## Complete new source

A fictional AUD plan costs $237 and $186, budget $430.

## Complete own invitation

An invented AUD plan costs $267 and $236, budget $500.

## Entry and teach

Teach sum minus one part recovers other on $18+$7=$25.

## Guided instruction

395 cost, 5 left; 395−148=247. Invite each relationship before the answer; teach missing facts and name help.

## Materials

Broad paper/empty bar or line/place-value headings as useful; usual communication; no actual stock/handling/purchase.

## Observe and follow up

Receive one available own relationship before staff possibility. If it matches criterion, offer another small new context later; this is not automatic mastery. If not, return to the entry relationship and fade one hint. Record the actual mathematical help. If access/time is not available, change access or sitting rather than marking wrong.

## Relationship to check

Teach the observed missing relationship in a new ordinary domain; not an answer repetition or further held item.

## Session sequence


1. Read the new source and name units/wanted quantity. Teach sum minus one part recovers other on $18+$7=$25.

2. Model on separate adult paper. 423 cost, 7 left; 423−186=237 checks. About 240+190≈430 is inconclusive.

3. Guide a different complete source. A pretend AUD plan costs $148 and $247, budget $400. 395 cost, 5 left; 395−148=247.

4. Receive one own attempt. An invented AUD plan costs $267 and $236, budget $500. Staff reference only: 503 cost, 3 over; 503−267=236.

5. Compare available work with: An exact connected check supports the decision; rough rounding alone does not. Choose one follow-up offer; never infer independence from a copied model.

## What to look for

An exact connected check supports the decision; rough rounding alone does not.

## Staff own possibility

503 cost, 3 over; 503−267=236.

## Teacher model

423 cost, 7 left; 423−186=237 checks. About 240+190≈430 is inconclusive.

## Timing

An adjustable 10–20 minute ordinary lesson, unpiloted; split/stop after one useful part.
