Ten optional 25-minute starts for Days 41–50. Children make an original two-phrase call and answer: an exact echo, a one-mark change, or a contrasting response. Broad role cards show who is invited to take a turn; nobody has to sing, play, speak, stand, touch a sound source, or perform for the class. This extends Weeks 7–8 phrase work. “Call and answer” describes this invented classroom structure, not a claim about a particular cultural musical practice.
Start with ten timed lessons, six original A–F practice aids, 30 same-target routes, 20 worked swaps, 20 optional everyday bridges, prompts and two fresh public checks O/P. The answer and response guidance are in the separate educator key. All eight A4 SVG/PDF sheets have exact text and tactile alternatives. Two original synthetic PCM cues are candidates only until an educator has listened and approved level on the intended equipment; their event transcripts and complete no-sound routes are included.
The exact ACARA v9/QCAA Prep crosswalk uses AC9AMUFE01, AC9AMUFD01, AC9AMUFC01 and AC9AMUFP01 with clear evidence limits. Paper shows an intended order, role, silence and source choice. It does not prove hearing, timing, sound production, timbre, audience receipt or response. A child-directed adult's playing is not the child's playing. Log any actual heard/made/shared event separately, only if it occurred. A real maker/context encounter remains in the authentic source slot pending permission and local selection.
Use broad fixed or raised cards, pointing, AAC, high contrast, a neutral reader/scribe, and an unpressured pass. Optional fictional settings never require family disclosure. The work is partial curriculum support, not a full term/year, formal assessment, efficacy study or accessibility certification. No QCAA/ACARA endorsement is claimed.
