When it comes to mathematics, standards aligned is achievement aligned… In the short time since "The Common Core Mathematics Companions" for grades K-2, 3-5 and 6-8 burst on the scene, they have been lauded as the best resources for making critical mathematics ideas easy to teach. With this brand-new volume, high school mathematics success is at your fingertips. Page by page, the authors lay out the pieces of an in-depth explanation, including: (1) The mathematical progression of each conceptual category, starting with modeling as a unifying theme, and moving through number & quantity, algebra, functions, geometry, and statistics and probability, building from the 8th grade standards; (2) The mathematics embedded in each conceptual category for a deeper understanding of the content; (3) How standards connect within and across domains, and to previous grade standards, so teachers can better appreciate how they relate; (4) How standards connect with the standards for mathematical practice, with a focus on modeling as a unifying theme; and (5) Example tasks, progressions of tasks, and descriptions of what teachers and students should be doing to foster deep learning. "The Common Core Mathematics Companion: The Standards Decoded, High School" has what every high school teacher needs to provide students with the foundation for the concepts and skills they will be expected to know.
