This is a fantastic tool for showing students dynamic relationships with tables, equations and graphs. Love the ability to save graphs and export them as images for use in other applications!
The website is great because it allows you to save and export work, assuming you create a sign in. The app is good for quick graphing and exploration, but doesn't have the save and export capability. Overall, it is a very intuitive tool, that is easy to use for beginners, while being rich enough in features to allow for more advanced uses.
How I Use It
I use this in a variety of ways. In whole class lessons, I may create a graph with dynamic capabilities to help illustrate a key concept. Other times, I create a dynamic graph that allows students to explore relationships and make conjectures. During individual work, many students use this as a supporting resource as well.
