0–4 launch: Show Soundwheel's ten-segment ring and ask why a picture might invite a unit shortcut. 4–9 source: Label the editor's ratio/percent conflation and three different desk-note quantities. 9–16 model: P/E=$20÷$2=10 as a ratio; yield=$0.60÷$20×100=3% for one stipulated year. Put labels on share measures before numbers. 16–27 independent route: Learners create a two-panel correction using equations, tactile cards or a private audio/AAC script. 27–32 audit: Partner checks that P/E is not a cash dividend, and future payments remain unknown. 32–35 exit: Collect ratio, yield, exact faulty word/visual choice and a source-bound correction. Give separate fresh Check B in an approved slot if its case is new to the learner.
Evidence log: day | source maker/audience and exact choice | model with unit/base | bounded revision | route and source access | content help | next move. Store only in a school-approved system; shared examples contain no real child data. QCAA mapping is partial; unit sequence and school instruments remain local decisions.
