Twelve whole tool-picture cards are available. Each complete pretend repair kit needs three cards. How many complete kits can be made?
Adult worked possibility · after own attempt
Name 12 as the whole available collection and 3 tool-picture cards as the required size of each complete pack. Take exactly 3 at a time into a new named pack; check that size before calling it complete. There are 4 complete packs and 0 whole tool-picture cards aside. 3+3+3+3=12; The requested number 4 names packs; 3 names members in one pack. A leftover group of fewer than 3 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.
