TeachSquare is a free and easy to use education platform for everyone who likes to teach, with live interaction between teacher and students.
Use the whiteboard with a set of convenient tools, talk to each other by webcam, create your own virtual classrooms,
and prepare and save your courses.
A real whiteboard.. well almost
TeachSquare's advantage to other teaching whiteboards is: students can use the whiteboard tools, but only with permission of the teacher. Just like regular teaching :)
