At the beginning of the year, I start off with some basic behavior guidelines (Success in 5...4...3...2...1). I'm not big on complicated systems that eat up valuable classroom time. Once the students have an understanding of our classroom expectations we work together to chart them out (using the student's own words and ideas).
This process serves as a reminder to the students and a heads up to new kiddos about how our classroom works.
Built in accountability without a lot of tracking and hassle!
