Some games that are appropriate for girls online at the age of 10 years are dress up games and princess games. The Nickelodeon and Disney websites may offer some good games featuring "Dora the Explorer" and Cinderella.
This really depends on what kind of website you are looking for.
Stardoll is a perfect choice.
