When classroom QR codes are useful
Classroom QR codes are most useful when students or families need to reach a digital resource from a printed page. Teachers use them for slides, videos, forms, digital assignments, parent newsletters, station directions, and take-home resources. The printable matters because students should see a clear title above the code and a readable fallback URL when possible. A QR page should also remind the teacher to scan the code before printing so broken links do not reach the class.
