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 theatre joins 376 tickets and 158.

Complete new source

A fictional tabletop map kit joins 258 and 167 tiles.

Complete own invitation

An imagined map box joins 247 and 185 tiles.

Entry and teach

Teach 8+7=15 and 10 ones=1 ten if needed.

Guided instruction

534; 400+120+14. Ask where a hundred boundary occurs. 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 8+7=15 and 10 ones=1 ten if needed.

2. Model on separate adult paper. 258+167=300+110+15=425; rename to 4 hundreds 2 tens 5 ones.

3. Guide a different complete source. A pretend theatre joins 376 tickets and 158. 534; 400+120+14. Ask where a hundred boundary occurs.

4. Receive one own attempt. An imagined map box joins 247 and 185 tiles. Staff reference only: 432; 300+120+12.

5. Compare available work with: An equivalent regroup and exact total retain every unit. Choose one follow-up offer; never infer independence from a copied model.

What to look for

An equivalent regroup and exact total retain every unit.

Staff own possibility

432; 300+120+12.

Teacher model

258+167=300+110+15=425; rename to 4 hundreds 2 tens 5 ones.

Timing

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