QR codes, that little square box that leads to mystery and engagement. Such is the case for the typical worksheet of math problems.
For example, you have the standard worksheet of several story problems that students need to complete for practice. This daunting worksheet where teachers find students practicing all the excuses to postpone the activity like "my pencil broke" or "can I use the restroom".
What if each story problem were revealed as the product of a QR code?
I was visiting a classroom last week, and looked at the walls noticing many QR codes scattered about. I asked what they are used for? The teacher stated she just put all the problems from the worksheet into QR codes; that students weren't motivated to complete the worksheet but eagerly engaged to complete the QR code tasks.
