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.
