My First Desmos Activity

For once I was actually planning ahead and thinking about how to introduce transformations of trig functions.

I wanted to use Desmos so I outsourced to Twitter.

Here's one from Tina Cardone and one from Christie Bradshaw. As usual, my mind had created something else, I just had to figure out how to get it to the students.

So I decided to teach myself how to use activity builder and make my own Desmos.

You guys.

It is sooooo simple. And elegant. And easy to learn. I had to google how to make a slider but other than it was very intuitive.

When I used it in class I was SO proud. I walked around with an iPad watching my students move slide to slide and answer questions. Every student was engaged and the classroom was totally silent. But they could see each other's answers so there was still some sort of communication.

I literally had to turn away because I was smiling so huge for no reason.

Here it is.

The next day we followed up with these INB pages:

Here are the files:


  1. Neat! Happy to hear that worked out for you, Elissa. Let us know if you need any help.

    1. I was trying to think of away to use the distance formula and slope to prove that a quadrilateral is a parallelogram. Do you know of anything like that?

    2. Great question. Desmos is great at Geometry (... yet #growthmindset). I'd probably turn to something like Sketchpad or Geogebra there.

  2. It seems to be a great writing stuff with realistic thinking. Kudos to writer!
