Both sides after substitution

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 imaginary display equation is 850−376=□+218.

Complete new source

A fictional archive equation is 700−268=□+195.

Complete own invitation

A pretend theatre-equation is 920−485=□+167.

Entry and teach

Teach 35−8=□+12: known 27, box 15.

Guided instruction

Left 474, box 256; both sides 474. 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 35−8=□+12: known 27, box 15.

2. Model on separate adult paper. Left 432; box 237; 237+195=432.

3. Guide a different complete source. An imaginary display equation is 850−376=□+218. Left 474, box 256; both sides 474.

4. Receive one own attempt. A pretend theatre-equation is 920−485=□+167. Staff reference only: Left 435, box 268; both sides 435.

5. Compare available work with: Both complete original sides are computed and agree after substitution. Choose one follow-up offer; never infer independence from a copied model.

What to look for

Both complete original sides are computed and agree after substitution.

Staff own possibility

Left 435, box 268; both sides 435.

Teacher model

Left 432; box 237; 237+195=432.

Timing

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