I am recommending the online Khan Academy to math students
The Khan Academy Website supplies a free online collection of more than 2400 micro lectures via video tutorials stored on you tube. It teaches math steps in all math areas. There are also lessons teaching History, Science, and Computer Science.
Salmon Kahn created this teaching approach and aid in 2006. He is a MIT and Harvard educated Mathematician and Computer Engineer. Please visit Wikipedia for more background and wide use of the Academy. He has been a presenter at TED, and a guest on PBS, NPR, CNN, and many other venues. As a lifetime Math educator, I visit the site often to review a Calculus formula, a Geometry therom, and to get ideas on presenting math lessons to my Algebra students.
