Public educator selection · preserve first work before criteria or later sources. These pages are public; record prior access.

Access and help

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.

Components

Criterion

Complete chosen conditions meet stated ranges, share a unit and make the wanted quantity explicit; target is given if needed.

Access

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.

Id

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

Read the new source and name units/wanted quantity. Teach source/unit/question on 12+8, target 25 before own formulation.
Model on separate adult paper. Ask whether there are enough: 132+175=307, 13 short. Label all givens.
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.
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.
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

Title

A wanted next move

Own initial value

Prompt

Choose a connected check. What would you keep, change or try next?

After own work: adult practice possibility

Staff possibility 384−148=236; keep note or propose 150 added instead. Proposed changed total is not claimed computed until worked.

Eligibility

After ordinary additive formulation, exact strategies and interpretation have been taught. If number ranges block access, teach a smaller ordinary version; do not silently change the stated held source and claim equivalent difficulty.

First later limit

First/later are opportunity labels, not fixed order, matches, calibrated difficulty or learning gain. If source/answer exposed, record that rather than claim unseen.

Id

D-first

Complete neutral source

Choose an imaginary collection or whole-dollar plan. Choose a start count from 100 to 900 and an added count from 10 to 300, both in the same unit. Ask for the combined amount or ask whether it meets a separately chosen target from 200 to 1200. State all chosen conditions. No real possession, purchase or completed activity is required.

Own page

Four labelled true empty text areas with literal blank initial values; kept draft not required for judgement; staff information behind separate link, not autofilled.

Source disclosure

Full neutral whole source is initially closed native same-page details on own response page; reading it never navigates away or loses typed work. No worked/criterion/next source inside its child disclosure. Staff index is separate.
