# The Conic Sections Project Saga Continues….

April 2012 edit: interested in how I present this activity, and many others, to teachers?  Check out my talk at the AMTNJ Tech Conference: 2014 Desmos Talk

Here on the blog, the conic sections project we use at my HS in Algebra 2 is one of the most popular posts, generating lots of hits and e-mails to me asking for more information.  I am just now grading conic sections projects for this year, and want to share some new additions to the project, and a rubric you can use.  The projects are all over my living room now, just waiting to be graded.

For the newbies to this project – the concept is simple: use equations you have used, specifically conic sections, to draw something.  The Desmos calculator is perfect for this task, and students turn in their graph-based picture, then a completed, colored picture.

So, what’s new this year?

In the past, students printed their equations and submitted them.  This year, students instead shared a link to their Desmos product using Edmodo.  Also, using folders has improved student organization, making it easier to locate and edit crucial equations.

VERIFYING SYSTEMS

In my conics unit, students learn to solve both linear-conic and conic-conic systems.  This year, I asked students to choose two systems from their drawing and verify the intersection points.  This served as a personal review of the chapter, and students had an investment in linking the algebra they had learned to their picture.

SCREENCASTS

Last year, I participated in a Desmos webinar where I explained the evolution of the conics project.  For the webinar, one of our sophomore students recorded a screencast where she explained an aspect of her picture.  Having a student comment and reflect on their work was so powerful that I made it a requirement for all students this year.  Many students chose ScreenCastOMatic to record, and the reflections were excellent.  Edmodo was used to share links, though some students had tech issues which I will work to head off earlier the next time I give this project. Below is a screencast from Nick, who was kind enough to allow me to share his work with you:

I have received many e-mails from folks asking for guidelines and a rubric for this project, and am happy to share with you a more detailed document.  Feel free to use any part of it, and let me know how it works in your classroom!
