I print these fun "badges" on Avery round labels 5293 (1-2/3 diameter, 24 to a page). When students finish reading the book and have completed all of the activities and or journals for a book they earn the "badge" for the book. It is a cheap (what teacher isn't looking for that) and highly motivational way to get my kids working hard. I use this method for all sorts of rewards in my room- but kids like to earn the special ones that match the books they read. Sort of like the sticker books of the 80's!
