Gather the kids together to make homemade Christmas tree ornaments. Get a white styrofoam ball and decorate it by rolling in glue and then glitter. Untwist one end of a paper clip and insert to use as a hook.
I have been looking for something easy to do with my 3.5 year old granddaughter and this is just about right for her. Another thing I'm thinking about doing is a gumdrop Christmas tree. Get a tree shaped piece of styrofoam, gumdrops and tooth pics. Break the tooth pics in half stick into flat edge of the gumdrop and the stick in the tree until it is covered.
