Looking for a great online tool for students who need to create visual aids for their presentations?
https://www.lucidchart.com/ is a tool that works with Google apps. Students can create and save flowcharts and diagrams to their Google drive in order to collaborate online on the project.
Another great tool is Create-a-Graph, from NCES. Students can choose bar, Line, Pie, Area, or XY graphs to create and then add them to their presentations easily. Highly recommended.
