I have played around with Google Classroom. I, however, have not really used it as a Classroom Management tool yet. My experiences involve providing help to students outside of regular classroom hours.
I am interested in knowing how others use a Classroom Management system to engage students as they learn content.
I think Class Dojo is a good tool to help with classroom management. It can be found at ClassDojo for Teachers
Class Dojo allows the teacher to give students points for demonstrating positive behavior at school. Parents can log into the secure site to monitor student behavior. The teacher can send parents text alerts as students earn and loose points.
