Where can I go to create a classroom floor plan?

I need to create a classroom floor plan, and it needs to be done electronically. Do you know of any websites??

You could try http://www.floorplanner.com/ and choose a Personal plan. Gliffy (http://www.gliffy.com/) is also a great alternative. They’re both free.
Good luck!
