Our behavior system that we have in place is called Class Dojo. Students earned positive points for many things such as participating, being on task, handing in their reading logs, returning papers, helping others, etc. Students loose points for behaviors such as being off task, yelling out, making noises, etc.
Parents can keep track of their child's progress through the APP daily. There is also a message board for parents to use to communicate with the teacher.
I have incorporated this behavior system in my past teaching and it has proved to be very successful. Students are allowed to cash in their Dojo points twice a week for small prizes, or let them accumulate for a bigger prize.
