Derive the equation of a parabola with Focus at coordinates (a, c) and Directrix at y = c using a Desmos graphing calculator. There is a companion worksheet for this activity, which subscribers can download. The worksheet is a PDF file.

Explore quadratic functions in standard form using this Desmos graphing calculator activity. In addition to graphing the parabola, it tracks the coordinates of the vertex and the axis of symmetry.

Explore quadratic functions in vertex form using this Desmos graphing calculator activity.

In this graphing calculator activity, have your students explore linear functions of the form y = mx. This Desmos template allows students to explore the effect of changes in the slope have on the graph of the line.

In this graphing calculator activity, have your students explore linear functions of the form y = x + b. This Desmos template allows students to explore the effect of changes in the y-intercept have on the graph of the line.

In this graphing calculator activity, have your students explore quadratic functions of the form y = ax2. This Desmos template allows students to explore the effect of changes in the coefficient a on the graph of the parabola.

In this graphing calculator activity, have your students explore quadratic functions of the form y = ax2 + c. This Desmos template allows students to explore the effect of changes in the values of a and c on the graph of the parabola.

In this graphing calculator activity, have your students explore quadratic functions of the form y = ax2 + bx. This Desmos template allows students to explore the effect of changes in the values of a and b on the graph of the parabola.

In this graphing calculator activity, have your students explore quadratic functions of the form y = ax2 + bx + c. This Desmos template allows students to explore the effect of changes in the values of a, b, and c on the graph of the parabola.

In this video, students learn about step functions on a Desmos graphing calculator. They then go about using the functionality of Desmos to create a moving escalator with a figure standing on it.

In this Slide Show, use the Desmos graphing calculator to explore square root functions.
