Mathematics educator Jo Boaler, of Stanford University, offers suggestions on how parents can help students learn mathematics. You can read her suggestions at http://yano.co.uk/2012/05/dont-let-maths-muddle-you-2. While that discussion was posted on a website in England, her observations hold true for students in the United States as well. This past summer Dr. Boaler hosted How to Learn Math: For Students, a free MOOC (Massive Open Online Course) through Stanford. A related MOOC is How to Learn Math: For Teachers and Parents. http://online.stanford.edu/course/how-learn-math-teachers .
