Target/codes: represent a new fictional source in three forms, correct a fresh symbol-copy mismatch, identify one empty personal category; AC9TDIFK02 and AC9TDIFP01 partial. Prepare: unseen Check A, A4 source, four broad physical tokens.
- Preview · 3 min. Explain this is a fresh public formative check. Save first child-controlled responses before showing feedback or the key.
- Source · 4 min. Read the new pictures, letters, puppet copy and empty category cards exactly, without naming the mismatch or personal answer.
- Model access only · 5 min. On an unrelated blank four-position row, show how to point, speak/AAC, draw or direct an adult; give no held source content.
- Child route · 7 min. Child represents all four source entries with broad physical tokens, pictures and symbols; finds and repairs one puppet-copy position; identifies an empty own-data category without a value.
- Check/respond · 4 min. Collect first work and adult support; then use separate public key. If source order drifts, model with a different practice source next session, not the held answer beforehand.
- Close · 2 min. Child points to an empty personal-data category that stayed blank; no actual value is shared.
