This scavenger hunt with QR codes is a fun group activity! Print the answer cards with QR codes and display them around the room. Group students and pass out the recording worksheets (each group starts with a different problem). Students must use two points to write an equation in slope-intercept form and scan the correct QR code to get to the next problem. They continue this process until they've solved all 10 problems. Several "answer cards" are actually common incorrect answers and will direct them to try again.
In each problem, students are given two ordered pairs and must write the slope-intercept equation of the line that passes through them.
Haven't used QR codes before? They're fun and easy to use! Just download a free QR scanner on your device and practice scanning the one in the preview to open the link.
