Look for actual replacement, correct nonstandard parts and unchanged whole. A supplied example is 20 + 2 = 22; choose it as teaching support after an own attempt when useful. If both versions remain, mark the ten represented objects and remove their old strip as the singles replace it. If the whole changes, count a new smaller account before/after one exchange. [Full plan](../teacher/day-45.md). Count supplied versus actual materials separately; child-directed adult acts show mathematical choice without proving motor performance. No viewer, returned homework or fixed quota is required.Original SubjectNest teaching and drawings © NeuroForgeIO Pty Ltd 2026, CC BY 4.0.
