I’m working on a Desmos Activity that will accompany a lesson on slope fields.

Currently, I am able to display a slope field and have a moveable point for students try to follow the slopes. On the next slide, students can select coordinates and view particular solutions that involve that coordinate. I also have students sketch particular solutions.

What I’d like is to have slides that allow students to input their own DEs (in the form dy/dx = …) and have the graph display this. I’m not sure how to take the student input and replace the g(x,y) = part of my graph.

Here is my work so far: Slope Fields • Activity Builder by Desmos

THANKS!
