The explicit, stated strategy of Common Core Mathematics is to emphasize understanding and conceptual learning over rote execution. And it does this, in practice, by teaching multiple different strategies for solving the same problem, and teaching why they all work the same. This, of course, leads to the hyperbolic frothing at the mouth on mommy-blogs and the like when a take-home sheet featuring just one of the many strategies taught is not the vaunted One True Trick that the parent in question learned as a child. Cue blogs titled "I'm a certified public accountant and even I can't do math this way!", which of course proves the very point Common Core is trying to make -- that older generations don't actually even know Math at all, but rather a bag full of tricks without a hint of understanding.
