Activity Builder

What will you build today?

At Desmos, we hope you’ll build an awesome online lesson that will engage, challenge, and enlighten your students. So really, we hope you’ll build young minds.

Activity Builder is a tool for helping you do just that. Whether you build something simple like a check for understanding to use in the middle of your lesson (Everybody graph a parabola with the vertex at (1,1)!) or a multi-step activity with multiple interactive graphs and rich questions, Activity Builder allows you and your students to move beyond the constraints of the paper handout.


You can see your students’ graphs on your dashboard—either individually or collectively—while they’re working. You can see students’ answers to the questions you ask and keep track of their progress through the activity.

Click on through to see how it works and get building.

See Match My Line and Match My Parabola for examples that you can use in your own classroom. Hopefully they’ll inspire you to build your own and share your creation with the world.
