I accidentally found a very nice site directed to kids, parents and teachers.
Here is some info from the website:
What is Bonus.com®?
Founded in 1996, Bonus.com® is a free, one-stop center of entertainment for the entire family. We offer Internet content within a protected playground that features hundreds of games, puzzles and other activities.
Why Was Bonus.com Created?
Bonus.com was founded so that kids could find fun, engaging content in one place without searching all over the Web or stumbling into otherwise inappropriate material. Every piece of content in our SuperSite is hand-selected for our audience by the Bonus.com editors.
What is the Special Technology of Bonus.com?
Visitors to Bonus.com do not need to purchase any special software to enjoy the protected environment of Bonus.com. Instead, Bonus.com operates with a special user interface called "NetScooter®". This is our unique and free way of simplifying navigation and encouraging kids to surf within the kid-safe pages of Bonus.com and not through the Web at large. In addition, Bonus.com uses ContourLine™ which establishes an invisible boundary around all content within our site. ContourLine allows our editors to include only the highest quality parts of a website for our visitors to see.
The pages had also a link to Conceptis puzzles ;)
With the search it was easily found but otherwise it was buried very deep:

I just wish teachers and parents use this!
