These low-stakes prompts guide next teaching. Keep the educator key away from first responses. Offer broad fixed A circle/B striped-square cards with words, raised equivalents, AAC, pointing, neutral reader/scribe or pass. Neither check requires sound, voice, instrument, timing, a real scene or an audience. Optional approved sound may follow the independent response and is observed separately.
Check U · read the new key
Day 75. U A4 SVG · U A4 PDF · exact text/tactile route. An unfamiliar five-place score reads A B B A B. A is the round key and B the striped-square key. Show all five source labels, then mark every gap between neighbouring places where the source label changes. There are four gaps to inspect. The task asks about the source key, not pitch, volume or whether these tones were heard.
Save first: full five-card reading, every chosen boundary, explanation and response route. Do not draw the boundaries for the child before saving.
Check V · one ending contrast
Day 80. V A4 SVG · V A4 PDF · exact text/tactile route. Make a new four-place source plan for a short ending: places 1, 2 and 3 use A; place 4 uses B, just once. Put one source card at each place. Mark the gap where the source changes and show or tell a musical reason for an ending contrast. You may invent your own reason; there is no prescribed feeling. The sheet does not show a completed score.
Save first: full four-card score, one chosen change boundary, intention and route. A paper ending cannot prove a child heard, performed or shared the sound.
