Friday Freebie: Desmos - Beautiful, Free Math!

Today's Friday Freebie is a great one for all my math geek followers! Don't be ashamed. I'm a proud math geek myself! If you're not a math teacher, please read on - if you share this site with your math friends, they'll love you forever.
Desmos.com is a free online graphing calculator that does some really powerful stuff. From plotting simple points to graphing linear and quadratic equations to shading areas between functions, Desmos does it all. (For you non-math readers out there, trust me - this is good stuff!)
You can enter multiple functions and color code each one. (See example below.)
You can even enter variables into the equation (like y=mx+b) and Desmos will create "sliders" for you so you can change the values of m and b and watch the graph change. This is a great tool to get students to explore and discover on their own.
If you create your account with your Google account, you can save your graphs directly into Google Drive. Then, they can easi…
