Common Core is the new wave in education. I think the ideas behind it are solid. Anytime people have to make changes it is difficult and uncomfortable. I feel people are unsure of all the expectations and this leads to people being apprehensive. It theory it would be wonderful if students in  all parts of a state or in the nation are at the same point in materials at the same grade levels. Even if everyone is striving to do this it will not happen every year with every class, because we are human and every student and class has their strengths and weaknesses. I believe we have just learned this lesson with "No Child Left Behind". I hope all educators keep an open mind and do what they do best teach the students the skills they need  to be successful in the world today.
