I need ideas for bday party games for different ages?

This weekend we are having a bday party for our 2 year old daughter. Ages of her cousins range from 3 - 11. I have thought of Pin the nose on Elmo (her theme is elmo)...guess how many m & m's are in the cup..bingo and possibly a coloring contest...but not sure. Does anyone else have any ideas? I have a lot of prizes
