It's a math site, but the games are fun and my kids like playing on it.

Poptropica is a great one--they have a series of puzzle games which kids her age enjoy. My daughter also enjoys the things on CoolMath--as the name indicates, the site has a variety of games intended to build math- thinking skills (not just adding/etc). Right now, my kids spend a good bit of time on Roblox, which has a big variety of games. You would need to point her towards the games which you think would suit her best, however it has such a big range that you can't go wrong altogether with it.

You can always ask her teacher what sights they use in class but ours used starfall.

There are also Nick, PBS, Disney, Sprout, and more. If you google games for kids online you'll find a LOT of places they can go check out.

Please remember, kids can get tired of learning and just want a fun game so don't rule out any games that are simply for the fun of it. We had one that the kids loved and they drove cars or boats or motorcycles on a track. Hours of fun.
