Video Club 6: Root Graph
In this video, a group of students discuss a square root graph and whether it can have negative inputs, and what that might look like if it did. This is a more formal classroom setting than some previous clips, where students in a school classroom discuss this under the guidance of a teacher.
Video Club Overview
Video Club Goals:
Teachers will attend to, make sense of, and see distinctions between the ways in which students represent possible inputs and outputs for the graph y=rt(x)
Materials:
Video loaded on Anotemos and shared with all participants
If watching in person, each participant should have a device on which they can view the video and headphones
Get ready (5 mins). Use Desmos or a similar tool to graph the function y = sqrt(x). What are the key features of this graph? How do you think students might talk and reason about what they see in this graph?
