Target/codes: independently revise an unfamiliar two-line score by changing only one lower X to REST and identify where together remains; AC9AMUFD01, AC9AMUFC01. Prepare: public R, R A4, broad REST card; keep key closed.
- Welcome · 3 min. This paper score puzzle guides next teaching; there is no hearing, physical turn or speed task.
- Access · 4 min. Show upper X X REST X and lower REST X X X. Brief: leave upper line unchanged; in lower only, change local count 2 X to REST; keep lower counts 1, 3, 4.
- Independent plan · 5 min. Child plans the complete revised two-line, four-column score and looks for any remaining column with two X.
- Child response · 7 min. Save first full answer and indicated remaining together place by cards, AAC, drawing, pointing or neutral scribe.
- Self-check · 4 min. Child traces both cells in each column, checks one lower change and intact upper, without a modelled answer.
- Close · 2 min. Consult separate key after the first response; further sound and audience claims need separate real evidence.
