A few years ago, I was appalled to read a New York Times story about a proposed new math program for New York schools that would promote guessing as a means of doing math. Kids would learn a way of estimating answers. The rationale was to cater to minority students, many of them Hispanics.
I read in shock. The whole concept of estimation made no sense to me. Worse, it looked to me like the liberal school system was really doing racial profiling, essentially saying the minorities are too stupid to learn basic math. Geez, get a life.
