Kids.gov - I'ts Not Just for Kids

Don't let the name fool you. Kids.gov may be geared towards students, but there is great information on the site for everyone. 

Kids.gov provides resources in all subject areas plus online safety, jobs and careers, and exercise and fitness.

Each category takes you to well thought out lists of websites for your students to use for learning. The site is filled to the top with options, and that may be a little overwhelming for students. I would recommend teachers review the site and find the exact links they want to students to use.
