A Desmos Proof Activity

I’ve recently been having a bit of a play with the Desmos Activity Builder and they have recently added an ordered list component. Because of this I have created a Desmos activity that explores proof by contradiction. This isn’t an area of mathematics I would naturally think to use Desmos for, but I have used this activity for revision with one of my classes and it seemed to go well.Screenshot 2019-05-10 00.53.13

The first screen is also my first real attempt at using the Desmos Computation layer, specifically I use the aggregate function to make a box plot of students estimates of \(\sqrt{2}\). Over the summer I want to explore CL properly and have a few ideas on how to improve this activity – watch this space.

Please use this activity and give me any feedback. Find it here.
