[quote=Anonymous][quote]You have no basis to say teachers know this math. And while this type of problem solving surely is not new it's not commonly taught, not now and not 50 years ago.[/quote] I was taught this approach by my teachers. Granted some of them had British educational backgrounds. I managed to use these principles and simplification "tricks" through high school, college, graduate schools and all of the standard American "useless" standardized tests (eg, SSAT, PSAT, SAT, MCAT, GRE..). There is no reason or need to ever use a calculator for these exams if you understand these principles. They apply to integers, whole numbers, natural numbers, fractions, decimals, and algebraic expressions. These basic mathematic properties are as old as your grandparents. Perhaps MCPS should sift through math teaching materials from the 1950s to build their 21st century curriculum |x|. Thefundamental problem is the quality of the teachers not reinventon of math curricule every 10 years. This gets quite resource intensive and expensive. [/quote]
