Desmos | Beautiful, Free Math

march 2015 by robertogreco

"At Desmos, we imagine a world of universal math literacy, where no student thinks that math is too hard or too dull to pursue. We believe the key is learning by doing. When learning becomes a journey of exploration and discovery, anyone can understand – and enjoy! – math.

To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Data tables open up a world of curve-fitting and modeling. Sliders make it a breeze to demonstrate function transformations. As browser-based html5 technology, the graphing calculator works on any computer or tablet without requiring any downloads. It's intuitive, beautiful math. And best of all: it's completely free.

Desmos is used by students, teachers, researchers, and general math enthusiasts from every state, and 169 countries. Join the fun! Launch the calculator"

Illuminations: Dynamic Paper

september 2010 by robertogreco

"Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? Or a set of pattern blocks where all shapes have one-inch sides? You can create all those things and more with the Dynamic Paper tool. Place the images you want, then export it as a PDF activity sheet for your students or as a JPEG image for use in other applications or on the web."

Statistical analysis, data and graphing | Timetric: making data useful

october 2009 by robertogreco

"You can use Timetric to show people your data and analysis as well; so the graphs you draw on Timetric can be embedded into your blogs and websites, and if the data they're based on is updated, they'll be updated too. You can set up alerts too, and get Timetric to email you when something interesting happens to a value you're watching.
