First of all there are tons of educational games to be played on all academic areas. Here is one on the U.S. States. These are the different categories:
There are learning activities that teach all kinds of topics. Here is one on the human body. Others include dinosaurs, state capitals, rocks and solar system, just to name a few.
There are educational songs to listen to. Check out this one on capitalization.
Next, there are movies that teach different topics. Check out this one on averages. Averages is a hard topic to teach, but this video does a great job explaining it so kids understand what averages are.
There are 32 movies available!
Also there is an online virtual world called Miamiopia that kids can join and explore. Registration involves creating a username and password. No email is required. Check it out here.
