Desmos is a free online graphing calculator tool that is available through any web browser or as an app for iPad or mobile devices. It has most of the functionality of a TI with some added features that I love.
- Desmos is INTUITIVE: The Desmos graphing calculator is very user-friendly and intuitive. There aren’t many special commands to learn or to find buried within menus, like on some graphing calculators. If you want to trace a graph there is no special button, just click and hold on the graph to see the coordinates.
- Desmos TABLES: Desmos supports function notation, and tables link to function values. Type in the x-values you want, and see them appear on the graph.
- Desmos SLIDERS: Sliders are my absolute favorite feature! Sliders allow me and my students to easily see how a parameter affects a graph. It takes just seconds to build an interactive demonstration for your classroom! Visit learn.desmos.com/sliders to view a quick video tutorial or to take an interactive tour.
Sliders are also a great way to animate graphs, which can be used to model a situation over time. I used sliders to create this animated Ferris wheel to model the distance of the rider from the ground over time.
- Desmos lets me SAVE & SHARE: Users can work on a problem, save their work, and share it with others. That means you can create a graph and then share the link with your students for them to access it. They can save their work and share it with you, or go back to their work later to add to it or revise. It also means that teachers can share graphs with each other instead of reinventing the (Ferris) wheel!
