About the Lesson

This lesson involves providing students with a visual representation of area estimation methods in order to determine which is most accurate.

As a result, students will be able to:

  • relate the left endpoint rectangle, right endpoint rectangle, and trapezoidal estimates of the area under the curve
  • use a dynamic comparison of the midpoint rectangle and trapezoidal estimates of area under a curve, relating these to the concavity of the curve.
