A joint publication with the National Council of Teachers of MathematicsThe Common Core State Standards (CCSS) for mathematics describe the "habits of mind" that teachers should develop in their students without which the content standards cannot be successfully implemented. This professional development resource helps educators grapple with the changes that must be addressed so that teachers can implement the practices required by the CCSS.Features include: A clear explanation of the CCSS for Mathematical Practice Techniques to help leadership teams collaboratively implement and maintain the new standards A proficiency matrix with examples of instructional strategies for helping students reach competency in each standard An example of how a fourth-grade classroom might implement the CCSS Reproducible, pullout tools to help with the change process, including an instructional sequence chart.By Ted Hull, Ruth Harbin Miles and Don Balka
