Goal/codes: Compare available observations and name meaningful differences; SFI02, SFI03, SFI04, SFU03 partial.
Prepare: Any two actual useful rows or NOTE plus its complete limits. Two physical tries are optional, not required.
-
Invite · 3 min. “Would another look help your question?” Child can choose yes, change question or finish. A previous shared row is usable; no new log from every child.
-
Name · 4 min. With guidance, name exact item/part, fold/form, gentle action and observation moment where known. “We did not record that” is accepted; no technical fair-test recital.
-
Try or compare · 7 min. One optional welcomed safe action or compare already available rows. Adult directs safety; child controls question/stop. Model route compares NOTE’s pressed and later-release stages, not an invented second physical trial.
-
Show · 5 min. Child puts two short phrases or broad outlines beside each other. “What is alike? What is different?” Match conditions only if actually checked; cloth folded twice is not automatically another material.
-
Decide · 4 min. Child chooses what they can say from the available sources and one still-open question. Changes in action/time/form can affect the comparison, so no isolated material cause claim.
-
Keep · 2 min. Teacher retains meaningful differences/interruption, not an elaborate audit sheet. One local item does not establish composition breadth.
Teacher keeps: one useful shared source/stage phrase or sketch, relevant individual idea/response and support; actual direct/report/model status. Add missing facts only if needed for the claim. Do not fabricate a prior prediction, physical trial or willing audience.
