I used this in my middle school math classes. I laminated them and put velcro on the back of them and also on the desk. They were placed on a corner of the student's desk.I used velcro so that the student can pick up the card if they need to. It included a classwork rubric and a behavior rubric for the student's classwork grade as well as the 8 Mathematical Pratices for the student to help justify his or her answer.
