I'm sorry Beaner is struggling. How do you know he just needs to try harder? What will earn him a green day? What is he doing to earn the other color days? Are the expectations above what he can handle? Does he have an IEP? I really believe in Ross Green's assertion that "children do well if they can" (have you read his book The Explosive Child?). I also believe in leaving school consquences at school; otherwise Beaner is going to spend his entire life in trouble. I think there's a reason Beaner isn't doing well at school, and your job is to figure out why (and no, ODD is not a good enough reason because it's a diagnosis typically fueled by an underlying cause). Sometimes the system created at school doesn't work for our kids; sometimes our kids mature at slower rates than other kids; sometimes an underlying disorder makes it difficult for them to "behave" the way they're supposed to at school. I hope you can uncover the real reason behind Beaner's challenges at school. Good luck.
