I happen to love Charades. I've played it as a kid, at birthday parties, college parties, etc., and I still love it. And the best part about it, is that it is very adaptable to various age groups and situations. All you need to do is have a list of things that the kids can act out. I like putting the items on slips of paper, so that the kids can draw one out of a hat. Here are some categories that might work well for kids:
Animals (farm, circus, jungle, etc.)
Things in Nature (leaves, trees, raindrops, etc)
People (pretend to be each other)
Action words (jump, run, skip, roll, etc.)
Vehicles (Car, train, airplane, etc.)
Body Parts (just have them point to their body parts and have people guess)
Facial Expressions (happy, sad, mad, bored, etc.)
There are of course many other categories that you can come up with. And you may need to allow kids to make noise, instead of remaining silent like we do as adults.
Mia, as an almost two year old would do really well at pointing to body parts, but she's not quite ready for the other categories. So as you plan the game, make sure that the options are appropriate for the age group.
Have you tried this with your kids? What words or categories did you use?
