Believe it or not, "Wii Tetris Party" might be what you are looking for! I have it, and it would be great for your situation. Two players can play on the same screen, on the same puzzle, at the same time - working together. Also, at her age, knowledge of shapes and geometry could be good for her! Nothing like a tried and true classic (rebooted for the Wii) to help out with introducing younger gamers to the genre! ..just my thoughts!
