I am a big fan of ClassTools.net, and I have blogged about them before. Both of these graphic organizers can be found there (plus a lot of other goodies!) You can not print or save unless you upgrade, but I have the kids embed them.
This one is from Holt publishing, and it is a PDF which allows you to enter text. It is a pretty good one, but this link will take you to a whole bunch of similarly formatted templates.
As my district moves closer and closer to our digital conversion, I am encouraging teachers to try these tools with their students so that they can get a feel for all there is to offer out there. That way, when the time comes for us to have 1:1 computers, it will seem like a gift rather than a challenge!
Do you have any great online graphic organizers you use? Can you share? I love to hear your ideas and comments!
