Vedic Math (VM) is a system of mathematics that allows students to do math about 10 times faster than the traditional methods without even having to write down any intermediate calculations. The results of applying these techniques appear almost "magical."
I have demonstrated these concepts at any schools and was even written up in the Daytona Beach News-Journal during one of my visits to Silver Sands Middle School. A copy of the article is at: http://www.news-journalonline.com/special/snapshots/2007/010807.htm
An internet search for "Vedic Math" would provide you with a wealth of sites describing the benefits of VM.
If you think that learning VM could be a great advantage to students you know, please contact me and we can discuss it further.
