On the other hand, Washington Post education blogger Valerie Strauss offers an extensive and valid criticism for "Why Young Kids Are Struggling with Common Core Math." And her criticisms are worth considering. The most serious issue is, of course, the potential ignorance that the standards reveal about the learning stages and styles of young children. While the Common Core proposed to offer deeper and more thorough teaching, it may simply be inappropriate. Strauss has addressed this issue regularly, notably in her Eight Problems with Common Core. And all concerned parties should at the very least have knowledge of her criticisms. That said, it's also important to acknowledge the claims that the Common Core is simply a step in the right direction in terms of standards actually being learning goals, as they should be.
That said, CC in theory is not a bad idea. It was an attempt by people to create a standard "floor" per grade level, so a kid who moved from Arizona to Illinois would be at roughly the same "grade level" no matter what. And it was an attempt to align grade level standards in literacy and math to some "standard" common to high performing nations, as well as better prepare kids for college and career. And, at least in math, the claim was that kids would "go deeper" and understand math "conceptually" in order to achieve "mastery" at each level. Thus, in theory, it's not a bad idea. And, in many ways, I am not opposed to CC, and have actually done a fair amount of promotion and staff development for at.
