Understanding Limits

Activity Overview

Students will use a graphing calculator to find a limit by graphing, investigating a table, and by using the calc menu. (See "Before the Activity")

Before the Activity

After investigating the limits of some continuous and non-continuous functions, students will be given an example for which these three methods don't, at first, appear to give the same results. Their assignment is to figure out why.

See the attached Activity PDF file(s) for detailed instructions for this activity.

During the Activity

Follow the procedures outlined in the activity.

Students will:

  • Be able to graph functions and find limits of these functions through graphing and investigating a table.
  • After the Activity

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
