I found two more great web sites for piano students and their parents.
Jan Taylor is a piano teacher in Washington state. I love her advice on helping your child to practice. Be sure to read her great article: http://www.kitsappianolessons.com/practicetips.htm
AN APPRECIATION OF CLASSICAL MUSIC
If you haven't seen the series, "From the Top at Carnegie Hall" on PBS, be sure to watch it with your children. The show has been on public radio for several years. The television series and the radio show feature some of America's most talented musicians ages 8 to 18 years of age. It is a great way to teach appreciation of classical music. The show's second season starts the first of May. You can watch episodes online at: http://www.pbs.org/wgbh/fromthetop/pages/about-the-series/
