I have read several times that sign language is a great tool for internationally adopted kids. When we got Polina she only spoke a few Russian words but she understood just about everything spoken to her in Russian. So knowing that, I bought a DVD called Signing Time. I played it in the car every time we went somewhere. Polina loved it and so did my boys. All three of them learned all of the signs within a couple of trips to the store. It worked so well we bought Volume 2.
