At the beginning of each lesson, the students collect their Workout Card and begin to work through it. I stop at each student's station to hear their pieces and to see how they are doing on their workout. These Workout Cards prevent the lessons from becoming chaotic as everyone knows exactly what they have to do.
If you think these workout card would be useful to you, print them off (double sided to get the lined page on the back), and try them out. Let me know how they worked for you.
