These are low-stakes checks for choosing next teaching. Keep the educator key away from first responses. Broad fixed phrase cards, raised four-cell strips, drawing, pointing, AAC, a neutral scribe and a pass are available. No singing, sound source, device, physical movement, public performance or personal story is required. Optional approved sound follows an independent paper plan and is separately observed.
Check M · postcard phrase order
Day 35. M A4 SVG · M A4 PDF · exact text/tactile route. Two new four-beat phrase cards are C = X X – X and D = – X – –. The paper postcard music plan starts C | D: C first, D second. The maker now wants D first and C second. Move the whole phrase cards. Keep all four marks inside each card in their original order. Show both four-place groups after the move and explain what changed. This is an invented paper plan, not a real song or postcard signal.
Record without coaching: first complete eight-place plan, labels/positions, internal marks, child's reason and route. A correct card order cannot prove heard musical order or Mathematics attainment.
Check N · the paper window finish
Day 40. N A4 SVG · N A4 PDF · exact text/tactile route. The starting paper music plan has two identical four-beat phrases: S | S = X X – X / X X – X. Keep the first S exactly as it is. In the second S, replace its first two separate short X marks with one LONG band across local counts 1–2. Keep REST at local 3 and X at local 4. Show the new complete two-phrase plan and say/show whether the second phrase now has the same or fewer separate sound events. A long band is one event covering two beat places. No one has to hold their voice.
Record without coaching: first full eight-place score, band position, unchanged first phrase, second-phrase event-count choice, explanation and route. Paper only shows a planned duration and variation, not an actually sustained sound.
