The Common Core State Standards aim to better prepare students for college and careers by shifting instructional focus to building knowledge through nonfiction texts, reading and writing grounded in textual evidence, and regularly practicing complex texts. In mathematics, the standards emphasize focusing instruction where the standards focus, coherence in linking topics across grades, and pursuing conceptual understanding, skill/fluency, and application of major topics. Implementation of the CCSS is intended to improve student achievement by integrating efforts to focus time and resources on fewer priorities.
