I would use QR Codes in the classroom for a number of activities. Whether it was literacy, math, science or any subject, QR codes get students used to using technology in a fun and creative way. The student would grab a cube and complete each of the activities as part of a daily task. I would use this in my 1st grade classroom.
Students can use the iPad to listen to a few stories by scanning the QR code. Download the app: QR Reader, and students can learn to scan the QR code independently. I've included a few favourite fairy tales and songs, which are linked directly to the YouTube video.
Rock Teach: Monday Made It Student Friendly websites with QR codes I decided to make a handy-dandy list of websites for students to visit. Some sites are educational and some are just fun. but all have QR codes so all students have to do is scan them in and they're brought to the site!
