These are some of the questions on the sets. The printable sheets have more, with the bead frame drawn for each, and an answer key.

15. 7 tens shared by 5 is 1 ten each, and 2 tens are left. They trade down to 20 ones. With the 5 ones that is 25 ones, so 5 each.
21. 6 tens shared by 3 is 2 tens each, and 3 ones shared by 3 is 1 each.
trade it down for ten ones. The ten trades down so it can be shared.
