I was looking at a list of best “fun” educational websites for children. What are truly the best educational blogs? YouthPlay has been around for years and I never see it on a list, but it is one of the very best.
You're in luck, A.R. Linder. Both my parents are teachers, so I'll just link you up with a source that they both have used.
If you are wanting to watch some educational videos (and read some interesting documents, see photos, listen to cool audio), try out TeacherTube.com. You might have to sift through everything to find fun videos, but it will be worth it.
Besides that, History.com actually offers a ton of games related to the subject. Just go to http://www.history.com/games. That may be a little more fun. ; )
Furthermore, you absolutely cannot forget JumpStart.com or MathBlaster.com. Both require accounts, but they are based on software that I used as a kid. They were good then, and they appear to be good now.
Khan Academy might be helpful for you.
Just try this site.
