This is an excellent site providing interactive text in a variety of subjects. I only checked out social studies, but there are various sections on math and science (some even in Spanish). Lessons are interactive and contain relevant images and great multimedia presentations. I highly recommend it.
Another cool thing about this site is that a teacher can set up an account and provide a custom HippoCampus page for his/her students. This can be helpful for all students, regardless of their abilities.
I stumbled upon this site the other day and it looks really cool! It's a Disney site where students learn how to start a business. It provides good basic and the activity is interactive. You should really check it out!
The History Engine is a web-based educational tool hosted by University of Richmond. Students use this site to learn history by researching, writing, and publishing specific episodes of American life. The online, searchable database contains works of students from all over the country. Excellent site for teachers, students and anyone interested in history.
A little outdated, but extremely informative database. If you want an easy access to US census information in all states, you can put in a zip code and you will get a lot of information from the 2000 census. You can also compare the data with neighboring zip codes.
