A fun QR way of reviewing limits and derivatives! Students embark on a scavenger hunt for 22 turkeys. Each turkey has a unique QR code that will link to a calculus question. 1 turkey has a special bonus and 21 turkeys have a question on the following topics:
- Limits (graphically, algebraically)
- Slope of a tangent line
---Sketching a graph
I usually have students in groups of 2-4. At least one student in the group needs to have a QR code reader on their device. I start with the "Welcome" page projected, and let student's read the rules/test their QR reader. I also let them pick one clue as to where a turkey is located to get started, and to spread the groups out. I hang these around the entire school and let the students search for as many as they can find. You could just as easily put them up around a classroom, or single hallway area. I usually phrase this as an "amazing race" style activity, and determine a winner based on number of correct answers as well as time finished. It takes approximately 2 days for students to get through all 21/22 turkeys, but you could have them do as many as they can find in 1 day!
