About Multiplication
A Resource for Teachers, A Tool for Young Children Autho red by Je ffrey Frykholm, Ph.D. This book is designed to help students develop a rich understanding of multiplication and division through a variety of problem contexts, models, and methods that elicit mu ltiplicative thinking. Elementary level math textbooks have historically presented only one construct for multiplication: repeated addition. In truth, daily life presents us with various contexts that are multiplicative in nature that do not present themselves as repeated addition. This book engages those different contexts and suggests appropriate st ra tegies and models, such as the area model and the ratio table, that resonate with ch il dren's intuitions as they engage multiplication concepts.These mo
dels are offered as alternative strategies to the traditional multi-digit multipl ication algorithm. While it is efcient, is not inherently intuitive to young learners. Stu dents equipped with a wealth of multiplication and division strategies can call up those that best su it the problem contexts they may be facing. The book also explores the times table, useful both for strengthening students' recall of imp ortant mathematical facts and helping them see the number patterns that become helpful in solving more complex problems. Emphasis is not on memorizing procedures inh erent in various computational algorithms but on developing students' understanding about mathematical models and recognizing when they t the problem at hand. Learning to Think Mathematically about Multiplication2About the Author
Dr. Jeffrey Frykholm has had a long career in mathematics education as a teacher in the public school context, as well as a professor of mathematics education at three universities across theUnited States. Dr. Frykholm has spent
of his career teaching young children, working with beginning teachers in preservice teacher preparation course s, providing professional development support for practicing teachers, and working to improve mathematics education policy and practices across the globe (in the U.S., Africa, S outh America, CentralAmerica, and the Caribbean).
Dr. Frykholm has authored over 30 articles in various math and science e ducation journals for both practicing teachers, and educational researchers. He has been a pa rt of research teams that have won in excess of six million dollars in grant funding to support re search in mathematics education. He also has extensive experience in curriculum development, serving on the NCTM Navigations series writing team, and having authored two highly regarded curriculum programs: An integrated math and science, K-4 program entitled Earth Systems Conne ctions (funded by NASA in 2005), and an innovative middle grades program entitled, InsideMath (Cambium
Learning, 2009). This book,
is part of his series of textbooks for teachers. Other books in this series include: Dr. Frykholm was a recipient of the highly prestigious National Academy of Education Spencer Foundation Fellowship, as well as a Fulbright Fellowship in Santiago, Ch ile to teach and research in mathematics education.

Learning to Think Mathematically about Multiplication 4 Learning to think Mathematically: An Introduction TheLearning to Think Mathematically Series
One driving goal for K-8 mathematics education is to help children devel op a rich understanding of numbers - their meanings, their relationships to one another, and how we operate with them. In recent years, there has been growing interest in mathematical models as a means to help children develop such number sense. These models (e.g., the number lin e, the rekenrek , the ratio table, the area model of multiplication, etc.) are instrumental in helping children develop structures OE or ways of seeing - mathematical concepts. This textbook series has been designed to introduce some of these models to teachers - perhaps for the first time, perhaps as a refresher - and to help teac hers develop the expertise to implement these models effectively with children. While the approaches s hared in these books are unique, they are also easily connected to more traditional strategie s for teaching mathematics and for developing number sense. Toward that end, we hope they will be h elpful resources for your teaching. In short, these books are designed with the hope that th ey will support teachers' content knowledge and pedagogical expertise toward the goal of providing a meaningful and powerful mathematics education for all children.How to Use this Book
This is not a typical textbook. While it does contain a number of activ ities for students, the intent of the book is to provide teachers with a wide variety of ideas a nd examples that might be used to further their ability and interest in approaching the topics of multiplication and division from a conceptual point of view. The book contains ideas about how to t each multiplication through the use of mathematical models like the area model and the ratio table. Each chapter has a blend of teaching ideas, mathematical ideas, examples, and specifi c problems for children to engage as they learn about the nature of multiplication, as well as thes e models for multiplication. We hope that teachers will apply their own expertise and craft knowledge to these explanations and activities to make them relevant, appropriate (and better!) in the context of their own classrooms. In many cases, a lesson may be extended to a higher grade l evel, or perhaps modified for use with students who may need additional support. Ideas t oward those pedagogical adaptations are provided throughout. Learning to Think Mathematically about Multiplication5Book Chapters and Content
This book is divided into
chapters. The first chapter, The Nature of Multiplication and Division, explores various contexts that are multiplicative in nature. While the idea of "repeated addition" is certainly a significant part of multiplicative reasoning, there are o ther equally important ways of thinking about multiplication. Contexts that promote these different wa ys of thinking about multiplication are presented in Chapter One. The second chapter, The Times Table, encourages students to discover and appreciate the many patterns that exist in the times table. When students are given the opp ortunity to investigate the times table deeply, they will discover interesting patterns and number r elationships that ultimately help them develop intuitive strategies and conceptual underst anding to help master the multiplication facts.
