I wanted to find a classroom management system that also taught my kids money management. I give each students a bank card. Throughout the week, I tell students they earn money for good behavior and they add it to their bank. Once a week, I have my students add up their money and they can write me a check for their purchases. I then take the money out of their bank by crossing it off their money bank sheet. If a student doesn’t have enough money for the item they want, I allow them to save up for the next week!
