How Can Teachers Use It? can be made accessible to your students in a variety of ways. Try placing the widget on your class website, or suggest that students download the free Android app to have calculator access on their phone. Practically speaking, if students are using this tool as their only graphing calculator, you may want to think about how this will work on tests; it can be harder to manage than a traditional graphing calculator because students access it through the Web and/or their cell phone. This makes it less obvious when kids use other Web-based applications to communicate with each other during assessments. If this is a concern, consider having a class set of regular graphing calculators and encouraging kids to use this site at home for homework and practice.

Is It Good For Learning?

It's simply a tool, so learning really depends on who is using it and what they're using it for. Compared to an actual graphing calculator, the price (free) can't be beat, and it serves the same purpose. However, could be improved by the addition of support for teachers using it with their classes. Currently, teachers who use it need to design their own activities and instruction sheets to help kids use effectively. A nice bonus: There's a free online math help forum. However, anyone can post responses to the questions, so reliability and quality of help varies.
