Students get confused when confronted with negative and rational exponents. At a bare minimum, they associate negative exponents with fractions and rational exponents have fractions. In this activity, students are forced to consider various permutations of negative signs, negative exponents and rational exponents all together. I created the problem set as a multiple choice exercise so that it would be easy to assess with a clicker system. I provide 8 multiple choice options so that it is just too difficult to guess the right answer. I have also created a Socrative online version of this quiz that I will make available for a small price for anyone that wants it. I use this activity in my flipped classroom. I usually use this after I've presented these problems to the kids interactively and out of order.
