If your school does not have a reading incentive program, you may decide to utilize Book Adventure as I have. It is a free resource for teachers. I set up my students and can track their reading throughout the school year, in much the same way as I would with Accelerated Reader.
I developed this tracking sheet for my students use because I wanted them to have a way to keep track of the books for which they had already earned comprehension points. This works for me, and I truly hope that it woks well for you.
