The Common Core Mathematics Companion: The Standards Decoded, Grades 3-5
What They Say, What They Mean, How to Teach Them

*Your user’s guide to the mathematics standards*

In the 12 short months since the ELA versions of *The Common Core Companions, Grades K-2 and 3-5*, burst on the scene, they’ve already assisted tens of thousands of teachers with the day-to-day “what you do.” Teachers’ one big criticism: what about mathematics? Luckily NCTM past-president Linda Gojak and mathematics coach Ruth Harbin Miles stepped up to the task. The result? That version of the mathematics standards you wish you had.

Page by page, *The Common Core Mathematics Companions *clearly lay out:

- The mathematics embedded in each standard for a deeper understanding of the content
- Examples of what effective teaching and learning look like in the classroom
- Connected standards within each domain so teachers can better appreciate how they relate
- Priorities within clusters so teachers know where to focus their time
- The three components of rigor: conceptual understanding, procedural skills, and applications
- Vocabulary and suggested materials for each grade-level band with explicit connections to the standards
- Common student misconceptions around key mathematical ideas with ways to address them

Don’t spend another minute poring over the mathematics standards. Gojak and Miles have already done the heavy-lifting for you. Focus instead on how to teach them, using *The Common Core Mathematics Companion *as your one-stop guide for teaching, planning, assessing, collaborating, and designing powerful mathematics curriculum.

### Webinar: Life's Too Short for Long Division

Learn from Linda Gojak and Ruth Harbin-Miles, authors of *The Common Core Mathematics Companion: The Standards Decoded, Grades 3-5*, the impactful models and applications that lead students to a better and deeper understanding of division.

*"This companion supports implementation of the Common Core Mathematics Standards with attention to the instructional shifts: focus, coherence, and rigor. The standard-by-standard examples provide an image of what the standards looks like in the classroom for both teachers and students. The attention to students’ conceptions helps teachers plan with student thinking in mind and contributes to the collaborative work of grade-level teams."*

*"This practical, exemplary resource supports teachers in their understanding and learning of the Common Core Mathematics Standards. The book does an excellent job of unpacking what the standards mean and makes explicit connections both to the Standards for Mathematical Practice and common student misconceptions. It is an ideal choice for a book study at either the grade or school level."*

*"This book is a ‘must-go-to’ for classroom teachers as well as coaches and leaders who support teachers in implementation of the Common Core Mathematics Standards. Connecting both the content standards and the practice standards with the effective teaching practices (*Principles to Actions*, NCTM, 2014), Linda Gojak and Ruth Harbin Miles provide the practical resources to enhance teachers’ understanding of the mathematics in the standards in ways that will bring them alive for all students. This is a book that will be the cornerstone of our professional development."*

*"*The Common Core Companion* series for ELA became a runaway bestseller because it made instructional planning to address the standards manageable—and meaningful. Jim Burke and his co-authors put best practices first, equipping teachers with the 'what-it-looks-like' teaching ideas for each and every standard. Teachers have been clamoring for math version for more than a year, and now it's here! Linda Gojak and Ruth Harbin Miles do an amazing job demystifying the standards for grades 3-5. The authors have created a format and design that will have teachers dog-earing this book as they plan for instruction!" *

*"I would use this book as a starting place to plan lessons because it gives a teacher a good idea of activities and some examples for each standard. It can also be used as a toolkit for understanding how standards connect across clusters and grade levels."*
