# A labelled strip collection

Use verified strips/singles to make a two-digit account and label object values. An ordinary starting amount is 35; 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.

Look for one strip worth ten and numeral connected to total objects. A supplied example is 30 + 5 = 35; choose it as teaching support after an own attempt when useful. If a child says five for three strips plus two, open one strip, touch its ten marks and label the object value. Then use a new two-strip model before returning to three strips. [Full plan](../teacher/day-44.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.
