I grade all of the "Math Blasters" as we call it, and it has been very helpful to know that the students can receive some type of anchor chart or notes on their current level. Also, I give the students a certain number of attempts before they go on to the next level and I believe it may be helpful for the students to see their progress as they see their number of attempts on their sheets. I also give the students prizes for their certificates as they achieve the next level and I find it helpful to see the students' achievements in order to give them their prizes. The more achievements they have on their formative loop report, the bigger the prize. : - )
