Mr. Harker had a great activity set up for students to do self guided learning through a "centers" format. Students were learning about archaeology. There were several stations set up for students to rotate through. Once at a station, they scanned a QR code using their iPad to access content they needed to complete that activity. Check out the pictures below to see how it looked.
For the activity pictured below, students were challenged to analyze pictures on some Google Slides presentations. After their analysis, they answered questions on a worksheet.
I hope this snapshot gives you some ideas about how to use QR codes in your classroom. It was great to see how QR codes can enhance well planned activity, linking students to content only accessible through the technology. Looking forward to seeing more examples from Smithton teachers!
