I work with over 30 schools in Bay Area, Chicago and New York as well, and have been working with teachers, districts etc on common core for the past two years. The entire point of CCSS is to make sure that WHAT is taught in a grade level does not vary. HOW varies so much from district to district, as each school/classroom contains so much demographic variability. My point was that it does not direct you "how" to teach kids division. Rather it provides guidelines that they should be taught division. Please go read the entire standards list and tell me if they contain anything more than suggestion on how to teach any mathematical curriculum. I agree teachers hate it, but its mostly because: 1. They are being forced to adapt to something without adequate amount of training 2. They have children with a whole range of skill sets which do not map to the common core for the grade levels they teach. So some children might be ahead and some might be behind for the particular grade level, so its hard to make sure that everyone in a grade level is mapping on the standards
