Carnival party - fishing game with magnets... kids catch a fish, a shark or a boot! I remember doing this at a party when I was 5. If I can remember that far back, it would be worth doing at a party for B someday.
Carnival Games for a Birthday Party Kids can fish with a homemade pole: Tie a magnet to one end of a piece of string and a yardstick to the other. The magnet catches construction-paper fish fitted with metal paper clips. The challenge? Kids are blindfolded. They get three turns to win: three tickets for a shark, two for a red fish, one for a boot.
