Target/codes: pair one chosen non-cultural geometric sign with one explicitly stated meaning in a fictional paper sorting game; AC9AMAFD01, AC9AMAFC01. Prepare:B invented legend, broad DOT/BAR and round/square tray cards, B notes.
Welcome · 3 min. A DOT does not always mean “round tray.” Today that is only an invented rule for this paper game.
Model · 4 min. Put DOT beside ROUND TRAY on a simple legend. Say “In my game, DOT means choose the round paper tray.”
Try together · 5 min. Compare BAR→SQUARE TRAY on B; ask child to trace each sign to its stated meaning. Read all words aloud.
Child choice · 7 min. Child selects a large original mark and assigns it one paper-game meaning, then places/directs a legend pair.
Notice · 4 min. Check child can identify both their sign and chosen meaning; do not correct it to an adult-preferred or universal mapping.
Close · 2 min. Save the child-defined pair; a symbol can become confusing if one card gives it two jobs.
