I use them simply for centers... put them on binder rings and students can choose a book they would like to "listen to."
Students use these daily as part of "listen to reading." They love them and are always excited when it is their turn to use it! As the year progresses, the reading goals for my students increases. I know that higher level picture books can be hard to find, but I know my students would love them! Most of my students are reading between a 3rd and 5th grade reading level. One thing that is difficult for my students is typing in the title of the book on the iPad when they want to quiz on the book. On the AR book find website (http://www.arbookfind.com), it gives the AR quiz number along with the book level. If there is space on the cards and time in your day, I think that it would be much easier for the students if they could just put in the quiz number rather than making sure they spelled the titles correctly. Just a thought!
Please leave any comments below on how you use these in your classroom or any other ways you use QR codes in the classroom. I always love hearing new ideas!
