I'd recommend picking up Wii Sports Resort, it's a load of fun with two or more people. However, you'll need to be picking up a MotionPlus with it if you'd like to play with your daughter (the game comes with one for free). It's worth it though, the mini-games are a lot of fun.
I'd also recommend Boom Blox Bash Party. I've never played it myself, but I have the original game, and it's a LOT of fun with someone else playing, so I'd imagine the new game is a lot better. It's very easy to get the hang of and just fool around with.
