I use these bookmarks with my second graders to keep track of their AR level and how many quizzes they have done well on. This is a great reward system to get the students engaged in reading and wanting to do well on the quizzes.
How I use them:
I determine the level that I would like each student to read at and put the numbers on their book mark.
Students read books at that level and log onto AR to take a quiz.
If the students get 80% or higher on a quiz they get a sticker to put on the bookmark.
Once the bookmark is filled with stickers (6) the students take it home. I reevaluate their reading level and provide them with another bookmark, usually with a higher reading level.
