Ready ordinary sources and simple preparation

Everything here is ordinary practice, not a held source. A broad pencil mark, read-aloud list, familiar AAC, sign, typed note or adult-directed drawing can replace purchased equipment. Printer, colour, touching, speech and a device are unnecessary. An adult reviews any actual environment/material and privacy before optional local activity. No risky object collection, public child survey or data upload is prescribed.

MODEL1 · Which paper game would you try?

Original fictional invitation to8 people; each offered one game choice, with a way to pass. Available reply list in source order: maze, matching, maze, story, maze, matching. Two invitations have no available reply. Choices: maze, matching, story. No-response records supply no preference and no reason. Full ordinary worked table: maze3; matching2; story1. Six recorded game choices and2 unavailable replies account for8 invited. This is not an actual class survey, dislike count or everyone's preference. C01 gives the interpretation and check.

MODEL2 · Which picture shall our pretend shelf show?

Original fictional8 invitations. Seven available replies: boat, bird, boat, tree, bird, boat, tree. One no available reply. Options: boat, bird, tree. Full table boat3/bird2/tree2; source check3+2+2+1=8. Bird/tree tie; boat is1 more than each. No real library stock, visit or purchase is inferred. C02 is the full worked model.

MODEL3 · Which shape shall our pretend garden sign use?

Six fictional replies: triangle, circle, triangle, square, circle, triangle. Intended options triangle/circle/square. All6 available:3/2/1; triangle is2 more than square. This is a shape-choice model, not a real garden encounter, plant-needs claim or measure. C03 is the full worked model.

Number sources

- Ordinary numeral labels305,350,503,530: order305<350<503<530. Use references300,400,500,600 with equal100-intervals, then choose positions within each interval. For the own408/480/804 task, a line400→900 with labelled hundreds helps.

-405: standard4 hundreds0 tens5 ones; another3 hundreds10 tens5 ones.236: standard2 hundreds3 tens6 ones; another1 hundred13 tens6 ones. Named value tokens100/10/1 are representations, not physical length measurements. -19+6=25;32−8=24. Choose counted marks, partition, bridge or another valid explained strategy. Calculator output is a check/help, not proof of an independent strategy.

- Project model46 needed/18 ready:28 more. New own model63 needed/27 ready:36 more. Both are fictional additive tasks, not actual stock, cost or completed delivery.

Use all20 contexts for complete source/method/check/limits. Separate genuine own blanks and models (aids/README.md) and full alternatives (aids/ALTERNATIVES.md). Adult reading supports access; giving a category, count or strategy supplies mathematical help. Do not expose held values/keys through an ordinary activity.
