What Wii games are good for a 5 year old

[Maxpphire]

My niece is getting a Wii for x-mas and she is only 5 years old. She can read some words and she can count but basically she is in kindergarten. My sister asked me what games might be good for a 5 year old and I suggested Mario Party but she thinks that might be too much for my niece to handle.

She likes racing games and I want to know as well does Mario Kart have a "free race" selection. Like you can just go and play and not have to worry about winning or losing but it would still tell you what place you came in at anyway.
