Common Core’s objective is to ‘equalize’ education for our children. CC was written, because some of our children cannot memorize math facts...so nobody memorizes math facts. Some of our children cannot express words based on English phonics...so nobody learns to read and speak correctly. CC withholds an early academic education from our students who place on the right side of the Bell Curve.
I spend 4 hrs a week teaching my son 6th grade math the right way so he learns the fundamental theory.
