Make an organiser that helps
Take 27 safe pieces or make 27 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.
Grown-up help
An ordinary example is 9 + 18 = 27. Show its reasoning only after the first own attempt if useful. This is a supplied model, not your household's stock. Full plan. If a plan is copied, offer a blank organiser and a new modest collection. If the reason ignores the job, name one need and compare two valid splits. If a part is uncertain, return to countable members. 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.
