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
