Stop negative behavior in your classroom before it starts by reinforcing your expectations and recognizing positive student behaviors. With two simple tools, I successfully managed student behavior at the secondary level. A ticket system and "shout outs" are little to no cost, require little work for you as the teacher, and will encourage on task, positive behavior from your middle school and high school students.
It's always my intention to praise students, however, we teachers get busy and tend to forget! These already made notes will help you remember and will take no time at all! In the beginning of the year, I'll print several copies and have them cut and ready to go!
