This is just a list of some interesting and fun tools you can use for your classes:

http://www.flashcardexchange.com/ - This site boasts over 9 million flash cards in all subject areas for you to access. Subjects range from Foreign Language to Math to even Automechanics. You have to create a free account to view the flash cards online. To download copies, I believe you have to pay a fee to join.

http://www.teacherxpress.com/ - A very busy site full of links for the busy teacher. Nothing like starting at a site full of links!

http://www.kaltura.com/ - A shared video project site. Create a group project for your students. Invite them to this site to upload their video clips into a shared account. The video then is collaboratively edited by group members. Risky!

http://www.etchy.org/ - A fun use of your computer and projector - an Etch a Sketch! Use the arrow keys on your keyboard to draw on this screen. Also there is a gallery where you can preview what others have done with their Etch-a-Sketches.

http://tumblr.com - Don't have enough to say in a blog? What about just needing a place to post a pic you like, a video that is fun, or a cool quote without having to make an entire blog about it?! Use Tumblr. You just add things to it as you find them. I use it like a wall for Post-Its. I just post my interesting finds on there. See mine: http://jadkins.tumblr.com

http://www.chartall.com/ - A free online chart maker. Great for making population grids. How about that Etch-a-Sketch?!

http://twittervision.com/ - The answer to the age-old question "what are you doing right now?" answered on a giant Google Map. Its fun to watch as people answer that question all over the world. You watch the popups occur in the regions where they answer from.

http://www.scrapblog.com/ - Use this site to create and share photo scrapbooks. If you think Power Point is the best tool for sharing photographs, use this site instead for your project. Its far more visually appealing and allows for student creativity!
