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

An invented stamp-game joins 427 and 132 entry cards.

Complete new source

A fictional puzzle catalogue joins 315 and 146 entries.

Complete own invitation

An imaginary comic archive joins 236 and 152 cards.

Entry and teach

Check why a total minus one part recovers the other on 20+7=27.

Guided instruction

559; 559−132=427. 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. Check why a total minus one part recovers the other on 20+7=27.

  2. Model on separate adult paper. 315+146=461; 461−146=315 verifies the original relationship.

  3. Guide a different complete source. An invented stamp-game joins 427 and 132 entry cards. 559; 559−132=427.

  4. Receive one own attempt. An imaginary comic archive joins 236 and 152 cards. Staff reference only: 388; 388−152=236.

  5. Compare available work with: A connected inverse and unit meaning support the total. Choose one follow-up offer; never infer independence from a copied model.

What to look for

A connected inverse and unit meaning support the total.

Staff own possibility

388; 388−152=236.

Teacher model

315+146=461; 461−146=315 verifies the original relationship.

Timing

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