Target/codes: preserve every A decision and B mark count while revising B's relation to A; partial AC9AMUFD01/FC01. Prepare: hold/change example, invitation G, two blank score copies.
- Welcome · 3 min. Offer an invented maker display, two paper lights or a learner's neutral context. Say, “We can hear/read a new relationship while keeping one part.”
- Model · 4 min. Read the practice first score A/B 1,2,5. Compare revision A 1,2,5; B 1,4,6. Name removed B places 2/5 and added 4/6; A and three B marks hold. This is different from the final unseen transformation.
- Try together · 5 min. Adult accidentally moves A's place 5. Ask what broke the promise to hold A; child directs restoration. Then remove the example before their composition.
- Child choice · 7 min. Child copies an own A line exactly to a second strip, copies B, then relocates one or two B marks while keeping B's count. Ask how any specific place's relationship changes and why they chose it. Adult copies only on child direction. If the learner wishes and local sound review passes, two willing makers try first and revised duo pieces at the same comfortable steady pace. Child chooses a preferred version or keeps both; no listener agreement is required.
- Notice · 4 min. Preserve both versions and all removed/added positions, not just an attractive finished score. If counts change, use one-to-one B token pairing and revisit the relocation. Record any assistance.
- Close · 2 min. A learner may prefer their first version. Choosing to keep it is valid; the teacher can note the demonstrated revision separately.
