Did you ever play Mad Libs when you were growing up? My brother & I did and I loved them. Well, I had forgotten about them, until Champ said they played them in Language as a fun activity. I think that is fantastic! It is a fun way to teach (or reinforce) nouns, verbs, adjectives, etc. Kids think they are playing a game and they are really learning!
You can purchase them (I've seen them at Books A Million) or you can play them on-line or download them. It's also really funny to make up your own. Just take a well-know children's story (like Jack and the Bean Stalk) and take out your own noun, verbs, adjectives, adverbs, etc.
Here are a few links for you and your kids. (Some are play on-line and some are printable.)
