Gliffy

Gliffy is an interesting site that enables users to create different types of charts. No signup is required and it can be used with students of all ages who need to create flow charts or similar types of charts. It is very easy to use and has many shapes to choose from. Teachers could use the flow chart option to have students visually depict the chain of command within the government (local, state, or federal) or add visualizations to steps within a recipe.

This site can also be used to create floor plans and would be a great way to revamp the old standard "draw a scale picture of your house/room" lesson and integrate technology at the same time. Gliffy can be found at http://www.gliffy.com/.
