Target/codes: transfer safe design steps to a new broad-paper stop-gate challenge, make/test if approved and evaluate actual result; AC9TDEFP01 (partial/conditional). Prepare: unseen Check B, new stop-gate sheet, adult-prepared large flat marker and broad sheet.
- Welcome · 3 min. Confirm clear tabletop, adult catch near its edge, slow short slide only and an opt-in plan-only route.
- Source · 4 min. Read the new START/END paper route and purpose without drawing a gate or predicting a passing result.
- Model process · 5 min. On unrelated blank paper say “two ideas, choose, safe steps, observe or NOT TRIED.” Do not make the held gate.
- Child route · 7 min. Check B A/B/C give two broad-paper stop ideas, choose and explain one, then safely fold/assist/direct and perform one slow tabletop slide if approved. Record STOPPED / CROSSED / NOT TRIED from actual observation only.
- Check/respond · 4 min. Ask which source line states the purpose, who handled materials, what happened and one next change. Keep first child-controlled response before public key feedback.
- Close · 2 min. A paper plan or author simulation cannot count as making/test success; schedule a later approved opportunity if needed.
The desk run-through checks authorship and internal consistency, not child learning or physical prototype performance. The educator must inspect the actual classroom materials and context.
