When the model breaks down:
But, the model for exponents breaks down when you start to consider the definition of something raised to the zero power, such as 5^0. In this experience you will have the opportunity to see how this problem arises, and then propose how you might resolve this issue if you were a teacher.
Participants view a depiction showing a lecture on exponent rules, then reflect on constraints on rules for exponents.
Participants view a depiction showing two students' competing definitions for a^0, then edit a depiction to show how they would respond.
Usage Note: We asked students to complete this module a day before class. We used that time to find interesting contrasting Then during class after the second session, you can
