Name 10 as the whole available collection and 2 label cards as the required size of each complete pack. Take exactly 2 at a time into a new named pack; check that size before calling it complete. There are 5 complete packs and 0 whole label cards aside. 2+2+2+2+2=10; The requested number 5 names packs; 2 names members in one pack. A leftover group of fewer than 2 is not another complete pack. Count or rebuild all original members to check; repeated addition, known groups or a supported subtraction model are possible taught methods, not a required memorised division fact.
