QR Codes in the Classroom
A worksheet with a QR code in the corner can check its own answers. A poster by the lab door can hold a safety video. The appeal for teachers is that one printed code turns any flat surface in the room into a link to something richer, with no logins to manage and no app to install. Here's what that looks like across subjects and grade levels.

Try one activity first
The lowest-risk starting point is a single station-rotation lesson or one scavenger hunt. Print five codes, tape them up, run the class, and see what breaks (usually the WiFi or one student's ancient tablet). Fix that, then expand. A teacher who starts with one laminated code learns more in a week than one who waits for a school-wide rollout plan.
