Target/codes: Compare two person-made flat layouts against the same source-separation purpose; AC9TDEFK01, AC9TDEFP01 as proposal.
- Welcome · 3 min. Revisit the two source names and the need to keep an invented card away from a real observation record.
- Read source · 4 min. Show two layout ideas: SIDE BY SIDE and TOP AND BOTTOM. Both are untested proposals with big zone labels and a boundary.
- Model · 5 min. For a wide imaginary desk, I might first try side by side; for a narrow desk I might try stacked zones. Keep both source labels visible. Say explicitly that no real viewer has chosen or used either.
- Child response · 7 min. For a stated wide or narrow pretend space, children choose a layout and show where a PRETEND CARDS card belongs. Change the space condition and ask if their choice changes. A child can direct adult broad-card placement with no touch.
- Check/respond · 4 min. Record the space, layout and purpose-linked reason. If “this is always best,” ask “For which desk and viewer?” If a card goes in the wrong zone, reread the source labels.
- Exit · 2 min. Point to or name the feature that separates the sources.
