Here is a terrific site devoted to fighting fuzzy math. The site has a rich collection of links to articles critical of the fuzzy-math plague. It can keep you reading for days on end.
I tutor math after class and see math cripples every day. I am now tutoring eighth graders being taught Connected Math who still don't understand equivalent fractions and can't solve the simplest proportion problems. The "algebra" they are being taught consists of counting little white and black boxes to see if there are more white or black boxes (to teach negative integers). This is EIGHTH GRADE!
