"Learning With the Pooyoos" on the Wii - you download them through the Wii. There were 2 "episodes" last time I looked, and they are $5 each. They are EASY. There are 2 levels, one lets you just press the appropriate button on the remote, the other lets the kids practice pointing the remote at the screen to click on the answer.
The game only lasts about 15 minutes & nothing has to be saved or anything. Perfect for short attention spans! My daughter loved it.
