THIS IS A REALLY BIG DEAL -- A FREE, POWERFUL ONLINE GRAPHING CALCULATOR -- THAT WORKS ON ANY DEVICE
Yes, I'm shouting. Desmos is a browser-based graphing calculator that works terrifically on any device. It's built in HTML5, so it even works on iOS.
To start off 2013, Desmos has added to its repertoire of functionality by launching Tables of Data. As the Desmos team says on its blog, "Tables are a student’s first way of organizing the logic of a function — number goes in, number comes out. They are the heart of statistics. They are one of the three legs of the representation tripod mandated by Common Core, along with symbolic (equations) and graphical (um… graphs).
If you teach mathematics, or use mathematics in what you teach, this is sure to mean a lot. Please check Desmos out and add comments below.
