I don't have any kids but I know what worked for us when we were younger and that was other kids! Our house was always the one that all the neighborhood kids went to. With other kids came ideas of what to do to have fun. Of course it didn't hurt that we had a swimming pool and horses, so those kept us pretty busy.

Some of the fondest memories I have of summer time were playing cards and boadgames with our friends. I would play Monopoly with my girlfriend for hours, everyday!

Other kids, boardgames, and cards (Double Solitaire was the best!) kept us busy. Oh yeah, that and Otter Pops!
