Choose two uses for a new collection and make two distinct valid splits. An ordinary starting amount is 13; smaller useful amounts are welcome. Use safe existing pieces, paper marks, tactile materials or direct the moves. Keep or revise your plan with a reason.
Grown-up help
Look for once-only membership, both part counts and a reason for the selected split. A supplied example is 5 + 8 = 13; choose it as teaching support after an own attempt when useful. If an object is counted in both parts, move one new small collection once into two outlined places; remove each object from waiting before placing it. [Full plan](../teacher/day-41.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.
