![]() Besides being available in a web-based version, its graphing calculator is also available as an app for devices.ĭesmos also gave teachers the ability to access full electronic lessons when it created its digital activity site. It’s extremely intuitive to use sliders give you the ability to see how things change Desmos made it accessible for a diverse group of learners, and it’s totally FREE for all to use. The graphing calculator is an amazing tool. Making artistic representations using math is a nice way to see the beauty in math. Make the connection between math and art – Sometimes as math teachers we get caught up in our curriculum, and we don’t take time to observe the beauty in math.In the past I would give notes like “adding to y will cause a vertical translation, but now I create graphs in the Desmos graphing calculator like this, and have discussions with the visual to reinforce the idea. I start with the black polygon, then I ask students “what if I add 3 to the y?” Then I can use Desmos to quickly verify their thoughts. “What if?” machine – Desmos gives me the ability to quickly verify conjectures from my students. ![]() Desmos emphasizes this by allowing you to observe these all at once. An equation can also be seen as a table of values and as a graph. An important part of math is understanding that some things can be represented in several ways. Connect representations – I was admittedly very bad at this when I started teaching.The following are some creative ways I use the Desmos graphing calculator in my class: I set up a tablet in her normal seat, gave her the class code, and she got to participate in a class activity even though she was thousands of miles away. I once had a student on vacation ask if she could do a Google Hangout because she didn’t want to miss the Desmos activity we were doing in class. Not only do I love Desmos, but so do my students. I try to be honest with myself and make sure I am not being impressed simply by the technology itself, but rather by what the technology enables my students to do (see student art pics). ![]() As an educator, I try to be very deliberate in my choice of classroom tools, especially with technology. There are numerous reasons why I use all of the various Desmos tools in the classroom. ![]() Over the years, Desmos has grown to include a variety of tools, and, as the company has grown, so has my passion for using it. I found several online graphing calculators that I liked, but eventually chose to stick with the Desmos graphing calculator. I started using Desmos several years ago because I was sick of doing so much graphing by hand (Algebra 1 teacher problems!). I have been an educator for 19 years, all of which have been in middle school and predominantly Algebra 1. Teaching is definitely something of a craft to me, and my favorite tool is Desmos, a free tool for teachers. Every good craftsman has his or her favorite tool. ![]()
