In this article, Paul Lockhart, once a professional mathematician and now a school teacher, eulogizes the love of mathematics in children and adults alike and hopes for its resurrection:
A Mathematician's Lament (http://pdfmenot.com/view/http://www.maa.org/devlin/LockhartsLament.pdf)
The author of A Mathematician's Lament has a (much shorter) follow-up in response to some of the criticism he received:
Lockhart's Lament - The Sequel (http://www.maa.org/devlin/devlin_05_08.html)
The original piece is long but I believe a "must-read" for homeschool parents and educators. Thanks V for posting that original link. It is a great analysis of what's wrong in the standard math curriculum and ideas for alternatives. Lockhart seems to advocate approaching math more like art with a focus on discovery and beauty.
Reading the first link reminded me of this piece I read on teaching science.
