Focus Questions
For use in a classroom, pause the video and ask these questions:
[Pause the video at 0:25] Ask your students to respond to the question posed to Haleemah and ET: What kind of numbers can we put in for the velocity, and are there any kind of numbers we can’t put in for velocity?
[Pause the video at 1:44] Ask your students if they agree or disagree with ET and Haleemah’s prediction that the scooter will “go basically nowhere.” Encourage them to explain their reasoning.
Supporting Dialogue
After watching this video, ask your students to discuss whether or not they are convinced that they could put in any value for v in the equation L = 3 • v + 4. If they think the equation won’t always work, ask them to state which values for v might not work and explain their reasoning. If they are convinced, ask them to articulate what convinced them in the video.
