Lucid Chart is a great tool for creating flowcharts in the classroom. Not only is it very easy to use but it also integrates with Google! You can create charts via the Google Drive screen and they save right to your Drive! Lucid Chart also offers free accounts for schools so check with them if you need a free account. (If you are with Stanly County Schools, please email me for login information.)
This program could be used in any standard that requires learning a process. Teachers can use it to create flowcharts for teaching and students can use the program to practice putting steps of processes in order.
