Hello, I was wondering if you had the URL to the winning graph? I am currently completing a math assignment where one of the components is to include a shaded region in my graph and I am unsure as to how to restrict the shading between two parabolas.

Thank you!!

Excellent activity. Thanks for sharing this idea and your worksheets. I have been amazed at how motivating this kind of activity can be for students, and I plan to use this with my Algebra students soon. We just looked at UCSMP’s “Square Grabber” to explore regression, so “dot capture” makes for a nice connection. Thanks!

stcarranza, thanks for the comment and questions! In terms of precision, I leave quite a bit of room for students. We do very little “solving” and a lot more visual tinkering/experimenting. Desmos is great at giving students quick feedback on their graphs, and graphical-guess-and-check is one of the more commonly used strategies on this particular activity. I have less experience with Desman, but when I’ve used it in class, I followed the same approach.

This looks like fun! I am wondering how precise you required students to be for intersection points. For example, if I want a restricted domain for a shape that has a parabola boundary, do I estimate its intersection with a second function or do I solve for the exact intersection? I guess I have the same question for the Desman activity as well. Thanks!
