Love this for the summer: Mom puts together lists under five different categories - Oh the Food we will Eat, Oh the Service that can be Done, Oh the Places we will Go, Oh the Crafts we will Make, and Oh the Activities we will Do; every Sunday, as a family, they plan out the week w/activities from the lists. *I love when someone else does the work for me.
