A template of the talk frame was used to plan a lesson for algebra students learning about radical equations. Students are given two equations, one with a radical, and need to determine when they intersect and what methods were used by the sample responses. In the Think section, the teacher recorded possible ways the scenario could be reworded, methods used to solve the problem are discussed in the Talk Idea section, and the We Understand section addresses the realization that extraneous solutions need to be checked and how to find such solutions.
