How I Use It
FooPlot is a free online graphing tool that is easy to use. Teachers can use FooPlot to demonstrate basic functions during introduction to concepts. Students can use FooPlot to visualize functions while completing homework assignments or as additional practice of certain concepts.
Overall, I find FooPlot to be simple but extremely easy to use. In addition to the website, there is a Chrome extension. FooPlot is available in several languages including English, Spanish, Dutch, and more. All graphs made on FooPlot are public domain, meaning they can be used in online exercises, worksheets, lesson plans, etc.
Some great features of FooPlot include: customizing colors of individual graphs and graph elements, changing the grid spacing depending on the function, pan/zoom features for different viewing perspectives, and the ability to download or share graphs.
There is a large advertisement at the top of the screen, which may distract younger or less discerning students. FooPlot is also limited to basic functions (trig, hyperbolic, miscellaneous), but I think it would be extremely useful for math teachers in middle school and up.
