Sal Khan is my hero. My 18 year old daughter recently introduced me to Khan Academy. Khan Academy is a free online resource for math tutoring and instruction with over 2100 instructional videos and 100 exercises.
The possibilities of Khan Academy are seemingly endless. For many it supplements the traditional math program. For others it provides an alternative to the the traditional instructional environment. But for those without access to school, the opportunities may be life changing. This is proof positive that one person can make a difference. Don't miss the TED video on Sal Khan and Khan Academy.
