For Thing 11 I posted about creating QR codes for the library. Unfortunately I found it challenging that with Kaywa you can only create 5 free codes. In my quest for another generator I found QRStuff and quickly fell in love. No signin is needed. You can shorten and print your code all in one step. There are many other options I didn’t try. My students were quickly able to create their own codes which we then taped in the books. Tomorrow we use the iPads to watch each others videos.
