What kind of party is it? Birthday or Holiday? How many kids are you entertaining? Are they all boys, all girls, or a mixed group (good luck with that, hahaha)
I've found that they are sort of into games, but that they may also enjoy some simple crafts they can do together at a table and have something they made to take home.
Pin the tail on the donkey, or the NOSE on Rudolph if it is Holiday
A very simple hide and seek game (Hide peanuts in the shell around the living room and let them keep what they find)
Guess the name of the song that is playing on the tape recorder
Sing some songs or let them do some simple cooking thing like: decorate a cookie, or make their own pizza. Or they can build a graham cracker cookie house.
Musical chairs is always a good one.
Duck Duck Goose is good-except you need some space
Have fun Oh, and go to Cardelean's profile page and scroll thru her hubs-she has several that are party ideas.
