QR (quick response) codes are codes that can be scanned with a smart phone (with a QR scanner app), iPad, or iPod. The scan automatically takes you to a web page (we like FotoBabble) where you can hear kids talk about their artwork, the process, the artist, their choices, etc. They've been amazing assessment tools for me, and the students have a blast recording their voices and taking photos!
