This is an around-the-room scavenger hunt covering simplifying exponents and radicals. Different from the typical scavenger hunt, each question is contained in a QR code. Students scan the code with a QR reader app on a smartphone or tablet, and get an image of the question. The questions are designed so that a student can begin at any card and cycle through all of the problems.
This is a great way to incorporate technology into your classroom in an engaging activity!
