C11 · Ferry-card bundles
Fictional ordinary teaching source. Keep the worked response with adults/after-own teaching; it is never a preset for a held own response.
C11
Seventeen whole ferry cards are available for a pretend map game. Every complete bundle needs four cards. Make as many complete bundles as possible and leave any cards left over aside. How many complete bundles can be made, and how many cards stay aside?
Adult worked possibility · after own attempt
Name 17 as the whole available collection and 4 ferry cards as the required size of each complete pack. Take exactly 4 at a time into a new named pack; check that size before calling it complete. There are 4 complete packs and 1 whole ferry card aside. 4+4+4+4=16; 16+1=17. The requested number 4 names packs; 4 names members in one pack. A leftover group of fewer than 4 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.
