Desmos Art Project

This semester I gave my Grade 12s a term project to practice function transformations. I began by sourcing the #MTBoS to see who had ventured down this road before. Luckily, several had and they had great advice regarding how to structure the task.

I use Desmos regularly in class, so it was not a huge stretch for them to pick up the tool. I did show them how to restrict domain and range (although most of them stuck exclusively to domain).

I gave them the project as we began to talk about function transformations, and they had 3.5 months to complete it. They complained, but the results were fantastic. (...bunch of drama queens).

Couple of important points, and then I'll let you peruse/steal the handouts and view the samples of student work (of which I am extremely proud).

Pointer #1: It was important that students copied a piece of art (this was typically a cartoon of sorts). Making them copy a pre-existing piece meant they must think about how the parameters shift to match. No lines are arbitrarily chosen.

Pointer #2: Illustrate how a variety of functions could model the same segment of line. When I do it again, I may even have weekly challenges as they are introduced to more and more function variety. Something small. I may project a simple image and ask, "What functions would you use to draw this?"

With all that out of the way, here are the materials I used:
I was skeptical throughout the process because they resisted giving me updates on their progress. On the whole, they were fantastically done. I can also say that they did very well with function transformations on exams.

Now that I (and you) have samples of work, it will go all the smoother the next time.
