Take 10 safe pieces or make 10 marks, or choose a smaller manageable amount. Use two or three spots to organise a job you actually want to do. Show each part; change the split while keeping the same collection. Point, say, sign or direct the moves. No return/photo is needed.
Try one small check: how do the parts account for your whole? If an empty spot is useful, it has zero. You may stop or finish privately.

An ordinary example is 2 + 8 = 10. Show its reasoning only after the first own attempt if useful. This is a supplied model, not your household's stock. [Full plan](../teacher/day-42.md). If zero is treated as missing work, place all ten objects in one region and point to the empty region. If only one split is copied, move one object and recount both parts. An adult can move under the child's direction; record a maths hint separately from reading or physical access. Home return is optional and is not a learning criterion.Original SubjectNest teaching and drawings © NeuroForgeIO Pty Ltd 2026, CC BY 4.0.
