Quick questions... I'm a 4th grade teacher but I'm going into my son's K class next week.

I'm looking for a project idea(s) to do with the class. I was going to read a book but it may be more fun to do something else.

Any ideas?

*it's also his b-day that weekend. I was going to bring in cupcakes and have them decorate their own but that may be a bit messy... thoughts?
