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.

Ordinary larger optional project, 20–40 minutes or several sittings unpiloted; not proof practical making, independence or whole code attainment.
Numbered moves
-
Read the complete fictional source; name wanted quantity and units. Select a representation after checking the day entry.
-
Make a source/problem/strategy note. Work the stated problem on own paper or usual communication.
-
Compare with a separate adult possibility only after available own work: 322 used and 723 start.
-
Build the intended tangible note/puzzle/gallery or exact description. Write two clearly different stories whose unknown roles match; keep numbers and units complete, then check each.
-
Try a different stated condition if wanted. Label the first and changed version separately; keep/check/change/pause/finish are choices.
Purpose
Write two clearly different stories whose unknown roles match; keep numbers and units complete, then check each.
Routes
Instruction

Instruction
Select one count to change by 10–50 while keeping nonnegative values. State all new conditions, compute and check; an uncomputed change is a plan.
