-
Welcome · 3 min. Choose a compact path and a broad path inside a personally comfortable space. Offer paper, AAC, adult-direction, and optional safe movement; anyone may pass on enactment.
-
Read and model · 4 min. Show original Source A: the same curved mark drawn compactly and then broadly. Say both are paper dance scores, not a child performance.
-
Try together · 5 min. Lay a tiny curve and a larger curve side by side. Ask what changed in the extent of the path while its curved kind stayed.
-
Child choice · 7 min. Child chooses a mark and makes compact and broad versions; adult records which dimensions the child chose.
-
Notice · 4 min. Ask what is visible on paper, what physical action was actually observed if any, and what remains unknown.
-
Close · 2 min. Save both versions for a size-change phrase tomorrow.
Next teaching: If sizes are indistinguishable, put frames side by side; if distinct, ask what remained the same. Use equivalent routes and worked practice.
