Math Whiteboard is an educational web tool I learned through Eric Curts. As its name indicates, Math Whiteboard offers a fully functional math work space for students, teachers, and anyone else interested in turning their math knowledge into concrete concepts. The tool comes equipped with practical features that make math learning much more engaging. 

Math Whiteboard embeds a powerful computer algebra system that supports complex calculations. Besides typing, users can also sketch or handwrite their math equations and move seamlessly between sketches, graphs and solutions. You can also import your PDFs into the whiteboard and use the tool’s internal editor to annotate them. You can even “make your PDF assignment files your background’. 

The collaborative features in Math Whiteboard allows you to share your whiteboard with students and work on the same workspace. You can create your own whiteboards to share with your collaborators. If you have a classroom blog or website, you can use the generated link to embed your math whiteboard in them. 

Math Whiteboard is entirely web based and does not require any software installation. As of writing these lines, Math Whiteboard is totally free.  Check out this video by Eric Curts to learn more about Math Whiteboard.
