Find activities that support your lesson plans

Challenge students to use and think about how technology can be used to model, analyze and explain math with standards-aligned activities in eight Precalculus topics.

Activities can be used as-is or edited to support specific objectives, align with popular text books and include technology tips to help you focus the learning and address student misconceptions.

# Featured Activities

## Exploring Vertical Asymptotes

This lesson involves observing how changing the values in a rational function affects the continuity of the graph of the function. Students will explain how the values in a rational function determine the vertical asymptotes.

## Crossing the Asymptote

This lesson involves the graph of a rational function of the form r(x) = p(x) / q(x). Students will manipulate graphs of rational functions and their asymptotes to determine whether they intersect.

## Polar Coordinates

This lesson involves a brief introduction to the polar coordinate system. Students will determine the location (quadrant) of various points given in polar form and recognize cases in which a point lies on an axis. Students will convert points between polar and rectangular form.
