This site is full of downloads for clip art. One of the teachers I did an observation for showed me this website. It does cost money, but it's a cute idea to use for letters sent home to parents or to decorate the classroom!
AMAZING website! Great way to get your students into understading how to use computers. You can post assignments, test dates, and even printable worksheets on this website. It's a virtual classroom!
This site does require membership, but it is worth it in my opinion! Everything is broken down into categories and its very easy to read. A lot of the projects/readings are directed towards everyday situations.
This is a great math resource. It is geared towards elementary and middle school math students. They have a ton of games and even videos on how to do certain kinds of problems.
