Focus Questions
For use in a classroom, pause the video and ask these questions:
[Pause the video at 0:22] Examine the data on the math task for temperatures from 1981 to 2010. How do you think the graph for this data set will compare to the graph from the previous episode? What similarities and differences do you predict will be visible?
[Pause the video at 2:35] How do the two functions compare?
Supporting Dialogue
[Pause the video at 1:39] Talk with a partner to discuss why it makes sense to find the value for A by computing the difference between the highest average monthly temperature and the lowest average monthly temperature and then dividing the difference by 2. How does that relate to the radius of a circle?
