We have a Sneetches picnic in the room. Beach towels, beach clothes, sunglasses, etc.
We plan a picnic lunch - everyone brings in an item.
Look at the site for recipes. Peanut butter sandwiches, lemonade, macaroni salad, star cookies, etc. We do cut stars in each sandwich. Parents come in to help. We watch the movie, play the game, and have fun.
I also use the peanut butter and jelly stuff for a supply and demand lesson. They have to negotiate to get what they need. It is great learning.
