Invitations: Shaped like a disco ball ( outside)  Inside: You're invited to last name's dance floor.  Be prepared for the dancing diva of your life!    Cake:  Sheet cake, frost w/ bright colors, and sprinkles if you like. Then make music notes or a boom box for the rest of the frosting.     Decorations: Colors-Yellow, red, orange, purple, and blue.  Cardboard cut-outs pictures of famous dancers.  If you have laser lights or black lights try them.  A Fog machine is cool too! (Put that on the invitation if you're going to have them there)     Games: Pin the tail on the donkey is a classic, even if you're a teen.      Give awards to all the so called dancers.     You could make up a dance and put on dress clothes to act like your favorite singer or dancer.     Have a parent dress and act as a DJ.  You can each put on an act in front of your friends so they could guess who you are trying to be like, like charades.     Goodie Bags: Include a pair of sunglasses, a disco ball key chain, photos of the kids dancing.
