New York Kids motivates kids to think and learn. I myself, am a former listener of the show, and I was very impressed with its quality. Bonus has a variety of things to do at their site. You can even play cool games. Literature is also involved.
Bonus allows kids to imagine, explore and create.
In my opinion, most educational web sites are boring. Well, CBC 4 Kids is educational and exciting at the same time. The Lab gives you the chance to perform many oozing experiments or take a look at an invention timeline. At this section, you can explore classic sports sounds. Check out the Homework Helper.
