I am a talented and gifted teacher for third and fourth graders. I have really had a tough time with behavior management in the 4th grade. The unit we are working on right now is banking so I thought that I could extend the banking unit into a b-mod plan for the year. I plan to "deposit" money into the kids' checking accounts for good behavior and "withdraw" for bad behavior. Kids will keep track of their account balance in a check register. They will be able to use their money to purchase prizes such as pens, pencils, lunch with me, etc. Any ideas on prizes and how much these should cost?
