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 fictional maze plan has 246 tiles plus 128, target 400.

Complete new source

An ordinary imaginary sculpture-card plan has 132 cards plus 175 new cards, target 320.

Complete own invitation

Choose imaginary start 100–500, added 10–200, same unit; optional target 200–800.

Entry and teach

Teach source/unit/question on 12+8, target 25 before own formulation.

Guided instruction

374, 26 short; learner may formulate total only first. 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 source/unit/question on 12+8, target 25 before own formulation.

2. Model on separate adult paper. Ask whether there are enough: 132+175=307, 13 short. Label all givens.

3. Guide a different complete source. A fictional maze plan has 246 tiles plus 128, target 400. 374, 26 short; learner may formulate total only first.

4. Receive one own attempt. Choose imaginary start 100–500, added 10–200, same unit; optional target 200–800. Staff reference only: No single answer; check actually chosen conditions. Staff new possibility 213+146=359, target 400→41 short.

5. Compare available work with: Own conditions and wanted quantity are complete without adult values fill. Choose one follow-up offer; never infer independence from a copied model.

What to look for

Own conditions and wanted quantity are complete without adult values fill.

Staff own possibility

No single answer; check actually chosen conditions. Staff new possibility 213+146=359, target 400→41 short.

Teacher model

Ask whether there are enough: 132+175=307, 13 short. Label all givens.

Timing

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