I have spent 25 years in manufacturing management and manufacturing engineering. I like to know how things work. I found that wikihow.com is a great tool for someone who wants to know how to do something. In the math category, I found that, in http://www.wikihow.com/Calculate-a-Square-Root-by-Hand, not only did wikihow show me how to do this operation, but then explained why it works, demonstrating the method graphically. I like this because sometimes I feel that the education of mathematics has become more about how to use a calculator or take a test, and not enough about understanding how the math works. For some, there is no need to go beyond how the use a calculator. However, for others, such as engineers, it would be nice for them to know why the calculations they just performed prove that the bridge they just designed will not fall.
I see this as a great supplement to a lesson, during class or as a means to encourage further exploration of a concept as homework.
