Access
Show, draw, type, sign, use your usual communication or direct an agreeing helper. Choose quiet/private work, switch a route, pause, pass or finish. One useful part is enough. A helper can read the exact words or scribe your choices; supplying an operation, count, regrouping or reason is mathematical help and is named. No speed, neatness, speech, handling or device requirement.
Adult model
675+148=823; 823−236=587 labels left. Check 587+236=823 and 823−148=675. A plan to use 236 is a model condition; only an actual authorised observation could establish real use.
Child direction
Choose a small planning problem you care about: a game, a collection, a pretend budget or a number puzzle. Make one note useful to someone else. Pick one route. Show what the numbers mean, try a way, then check one result. You can stop after a useful part.
Common tangle
the plan lacks given counts; check the roles and equivalent quantities, rather than memorising a printed answer.
Day
60
Different guided practice
Guide a different fictional game: 508 cards, 176 arrive, 245 used; 684−245=439 left. Ask the learner to select addition then subtraction from roles, not follow a hiddenpreset. Receive one useful step if the whole chain is too much.
Check and teach the entry relationship
Review actual work. If partitioning, unknown roles or comparison remain unclear, choose that teaching instead of an open project. For a new problem teach identifying given counts/unit/wanted quantity with small 12+8=20 first.
Hook
Choose a small planning problem you care about: a game, a collection, a pretend budget or a number puzzle. Make one note useful to someone else.
Materials
Broad paper, labelled place-value/part-whole/number-line alternatives as suitable; optional familiar safe counters; usual communication. No hundreds of loose marks, purchases or physical handling required. Keep adult model and own work separate.
Next ordinary teaching
If the plan lacks given counts, offer empty start/change/question headings and neutral scribing. Teach one missing relationship using fictional 35 plus 18 then 12 used=41. Invite a new own small problem later.
Complete fictional source
Adult example: a fictional making station has 675 labels, receives 148 more and uses 236. How many remain? No real making or stock count is claimed.
One own invitation
Choose one result from your own problem. What does it count and what check supports it?

Instruction
Choose a small planning problem you care about: a game, a collection, a pretend budget or a number puzzle. Make one note useful to someone else. Read the source. Ask what the numbers count and the wanted quantity. Review actual work. If partitioning, unknown roles or comparison remain unclear, choose that teaching instead of an open project. For a new problem teach identifying given counts/unit/wanted quantity with small 12+8=20 first.

What to look for
Available own formulation, strategy, result, units and check agree; unsupported or unfinished steps remain visible.
After own work: staff possibility
No prescribed own numbers. Fixed routes below have separate staff possibilities. Check against the learner actual stated conditions; do not fill missing choices from adult work.
