# N05 · Pack by a rule you can explain

**A small start:** Choose material headings. Where does each entry fit?

## Complete supplied source

Original fiction. Box entry says cardboard and used to hold pretend books. Tag entry says paper and used to name a shelf. Wrapper entry says it covered an imaginary parcel, but gives no material. No manufacture dates or material samples are supplied.

## Choose your way

Tell it, sign, use AAC, point to the words, make broad marks or direct a helper. Two reachable paper spaces are enough if wanted. Start with one clue, keep it private, rest, pass or stop. A helper can read dates or source names neutrally and write the child’s exact chosen words; record any supplied idea separately. These are choices, not fixed learning styles or diagnostic labels.

**Teacher invitation:** Keep each entry beside its source name. Invite explicit headings, then one reason for a placement. A child may choose separate cardboard/paper groups or a stated broader paper-based group; the helper does not silently change the rule.

**One worked possibility, after an own attempt or if wanted:** Under separate headings, Box is stated cardboard, Tag stated paper, Wrapper material unknown. With an explicitly stated paper-based rule, Box and Tag can be grouped together; Wrapper still has no material clue. “Covered a parcel” does not prove paper.

**What stays unknown:** Unknown material is not automatically a non-paper material. No source says which item is stronger or newer.

**Next teaching:** Add an invented tin entry with metal stated. Ask where it fits under the child’s existing rule; if the question changes to use, build new honest headings rather than reusing material groups.

**Keep a useful trace if needed:** chosen source/question, exact child meaning, actual helper reading/writing/moving/operation, content help and one useful next step. Missing or unoffered evidence is not a failure; a fictional action is not the child’s performance. There is no length, handwriting, speed or public-sharing requirement.
