Every so often, I randomly run across things that could be insanely useful. One such thing is OpenDyslexic:
OpenDyslexic is a new open source font created to increase readability for readers with dyslexia. The typeface includes regular, bold, italic, and bold-italic styles. It is being updated continually and improved based on input from dyslexic users. OpenDyslexic is free for Commercial and Personal use.
The featured image above is a snippet of their license, using the font. If it looks like something you or your students could use, go to http://opendyslexic.org/ and download it for your device!
