This is the management tool I use in the middle school right now. It utilizes a positive/negative system where students are rewarded with a "positive" for good behavior and a "negative" for choosing negative actions.
I print this front and back on card stock for durability. This will get a 2 week use out of each card per student. Students carry them through the day to each class and then leave them in their homeroom at the end of each day. Although, you can have them take it home each night.
The responsibility card also features:
-Parent signature line (I send them home with the kids every Friday and they return signed on Monday)
-Place to put current class grades so parents can see progress
The reward system is up to the team or individual teacher.
This is a word doc, so you can change it to meet your needs.
