I've heard of QR codes and have scene them used in mobile advertising. I've even heard of some really good ideas on how to use them in class including a QR code scavenger hunt. Our school is 1:1 with iPads in grade 9-12, and I've been pondering for awhile on how I could use QR codes in my own classroom. Then, and idea struck me as we approach Ch. 6 & 7 of Huck Finn. In those chapters, Huck stages a crime scene to make it look like how was murdered. Brilliant, I know. But most students don't see his genius behind this. So I decided to do a QR Code Crime Scene prior to reading these two chapters.
