Desmos - A Graphing Calculator in Your Browser

Desmos is a new company that has created a fully functional, browser-based  graphing calculator. The calculator performs all of the functions you would expect to see in a graphing calculator with a couple of extras that you don't find in typical graphing calculators. Desmos allows you to share your equations and graphs through a Bit.ly link. Desmos graphs your equations as you type them and redraws them as you alter your equations. Watch the video below to learn more about the Desmos calculator.

Read TechCrunch's post about Desmos to learn more about the company and some of their plans for the future.

Applications for Education
Desmos could be the replacement for those expensive TI calculators that sometimes disappear from schools. I like that you can share your work via shortened Bit.ly links. I could see teachers modeling with Desmos and sharing. I could also see students sharing to do collaborative problem solving. The one thing holding Desmos back is that it's Flash-based and not ready for the iPad yet.

Common Core Standards on Your Mobile Device

Mastery Connect recently launched a free app for Android and iOS that is designed to help educators quickly locate the common core standards for mathematics and language arts. To locate standards through the app just select the content you teach and the grade level you teach. The app will pull up the standards based on your selections. Get the Android app here and get the iOS app here.

Applications for Education
The Common Core app isn't going to revolutionize the way you teach, but it certainly will make it convenient to find the standards that you need to know.
