Useful outcome: Sort the same collection in two useful ways without losing source labels.
Prepare: O1/O4; two large spaces; blank sort mat.
Partial opportunities: AC9HS1S01, AC9HS1S02, AC9HS1S03. Refer to whole authority and explicit limits in the linked curriculum scope; opportunity is not observed mastery.
-
Start ·3: Read child invitation I03 in the ordinary source menu. Invite a wanted useful product. Offer private work, rest, pass, stop or another route.
-
Source/model ·5: Fresh invented kitchen cards say paper wrapper, cloth wipe and material-unknown bag; a material rule needs an unknown group. Adult demonstration stays separate from child evidence.
-
Guided source work ·part of 10: Use O4's four described play items. For “Which items are paper?” sort by stated material. For “Which use turns?” sort by described use. The folded path belongs in both paper and turns; a sort changes when the question changes.
-
Own useful work ·rest of 10: Child chooses a question/rule, places or describes all four items and explains one placement. Keep insufficient-information as a possible group; an unstated material is not proof of non-paper. Then choose a different useful rule and re-sort one or more items.
-
Compare ·5: Check whether another child or self can identify the rule from the group label. Record actual re-sorting, not an assumed cognitive gain. Overlapping categories are allowed when the rule makes this explicit.
-
Notice and teach next ·2: If colour quietly replaces material, sort fresh invented kitchen labels by stated container material first. If one item is forced into exactly one group, use fresh invented postcard that is both rectangular and paper.
Three ways to take part
(a) Two-room collection: Draw two broad rooms labelled with the chosen criterion and direct the object descriptions into them.
(b) Sorter radio: Describe each placement by usual communication; a helper moves only what the child directs.
(c) Change the question: Make two small lists for two different questions and point out one item whose placement changes.
All routes retain the access/attribution/stop choices above. Observe: An explicit useful rule, source-supported placements and a reasoned re-sort or unknown.
Extra contexts: C05/C06; home: H03; optional larger making: X03; written read-aloud: N03. Full source/own/staff separation follows the linked assessment selection guidance.

O4 — Sort for the job
Original fiction, play-folder descriptions written 2026. Folded Path: paper, a turn-taking path game. Story Patch: cloth, used to tell a pretend story without a recorded turn rule. Picture Pair: paper, a matching game with turns. Mystery Board: material not stated, used for a turn-taking guessing game. No manufacture dates are supplied. Under a paper-material question, Folded Path and Picture Pair fit; Mystery Board belongs in material-unknown, not automatically non-paper. Under a turns question, Folded Path, Picture Pair and Mystery Board fit; Story Patch has no described turn rule, rather than proof no storyteller ever used turns. The two question/rule sorts need different honest group headings.
