Grading for my star

After having talked to various mom's and reading on the net, and discussing it with a counsellor - I've designed a grading pattern for Rishab. I really don't want to structure and rate his day to day activities and behavioural pattern in this cold objective manner, but am hoping rather to involve him in evaluating himself. I hope to achieve an improvment in his overall behaviour and conduct in the class room. A sense of responsibility and adherence to a discipline is very important at this stage.

Not sure though, of the efficacy of this mechanism ...
