Instructional Ideas
  • Stop the video and have the class work the examples then restart the video as it works through the solution
  • Use the video to introduce a lesson on evaluating functions for inputs in their domain
Classroom Considerations
  • The class should be familiar with evaluating expressions at given values
  • This video is hosted on YouTube
Pros
  • When working out examples, the presentations highlight the steps taken to evaluate the function
  • The chosen examples reinforce concepts learned earlier
Cons
  • The alignment to the standard is not exactly correct; a better alignment would be HSF-IF.A.2
Common Core
HSF-IF.B.5
