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 story book plan changes start from 327 to 347 and keeps 156 added.
Complete new source
An ordinary fictional costume plan changes its added count from 148 to 168 while current start is 286.
Complete own invitation
Choose an own complete additive plan, change one count by 10–30 and recompute.
Entry and teach
Do not retain old answer after changing an input.
Guided instruction
Current 503; old 483 is earlier version. 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
-
Read the new source and name units/wanted quantity. Do not retain old answer after changing an input.
-
Model on separate adult paper. Current 286+168=454; old 434 belongs to 286+148. Label both versions.
-
Guide a different complete source. A pretend story book plan changes start from 327 to 347 and keeps 156 added. Current 503; old 483 is earlier version.
-
Receive one own attempt. Choose an own complete additive plan, change one count by 10–30 and recompute. Staff reference only: Check the actual new sum; staff possibility 248+135=383 then 268+135=403.
-
Compare available work with: Current calculation uses current values; earlier result is not silently reused. Choose one follow-up offer; never infer independence from a copied model.
What to look for
Current calculation uses current values; earlier result is not silently reused.
Staff own possibility
Check the actual new sum; staff possibility 248+135=383 then 268+135=403.
Teacher model
Current 286+168=454; old 434 belongs to 286+148. Label both versions.
Timing
An adjustable 10–20 minute ordinary lesson, unpiloted; split/stop after one useful part.
