I have had multiple successes with this version of a behavior chart. I simply staple the sheet into a file folder (I let students choose their own color) and check the chart each day. The format of the chart forces students to take ownership of their behavior.
Students set their own goals (+'s for the week) and choose their own rewards. They fill out the chart after lunch and at the end of the day. The reflect on their behavior and then we have a discussion of what they did well and what still needs work.
*Easily customizable for students' target behaviors.*
