Split a teen amount your way

Take 19 safe pieces or make 19 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 10 + 9 = 19. Show its reasoning only after the first own attempt if useful. This is a supplied model, not your household's stock. Full plan. If ten-and-ones is the only accepted split, physically move two objects between parts of a different teen. Check each part and recombine. If equal sharing is imposed, choose two jobs with different needs. 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.
