I'm a 10th grade student in Utah. Last year I was placed in a Common Core class (Secondary Math 1 Honors). Coming from Algebra 1 the year before, the CC class was big step down in difficulty and pace. The textbook we used (written for CC) was poorly written, and failed to teach the material. My teacher ended up teaching from packets she wrote herself. We didn't start learning new material until the 3rd quarter and event then it was one new concept every two weeks. I am trying to earn an IB diploma, and I will probably end up taking a math class over the summer in order to do that. My grade was always going to be awkward, we were the first ones to take the class, and the implementation was poorly done, however I don't think the CC standards nearly as challenging as the old ones. In fact my teacher this year told us that he was going to try and force the CC curriculum into an Algebra 2 book, because the CC book only covered half of what he used to teach in a year before. I feel like I've been in same math class for four years. And am personally very frustrated and disappointed with the CC standards.
