Another perspective...
I am an educational consultant for one of the states that is implementing the Common Core. I encourage you to talk with the teachers and possibly read the introductions to the standards themselves. The Common Core standards identify what students should be able to know and do by the end of each grade. It does not define how teachers should teach or what materials, activities, strategies, or methods that should be used to reach the standards. The curriculum chosen by the school hopefully aligns with the Common Core. The ultimate goal is to make sure the students are prepared for college and a career. I am not familiar with the math standards, because I am a literacy consultant, but I like how the standards place more of an emphasis on ALL teachers being responsible for the literacy of the students. I want my daughter, who is in 4th grade, to be able to read and understand the complexities of science and soc. studies text at the 4th grade level, which is written differently than narrative text. Students certainly have to learn different strategies to engage in different kinds of texts. The teachers should know what those strategies are and how to explicitly teach students how to use these strategies. In my state, the Common Core will not require more testing, but just a different state test that students have to take annually anyway. I just wanted to share another view, so I hope this give some additional information.
