Product Description

By Carne Clarke, William Fisher, Rick Marks, Sharon Ross, Rose Mary Zbiek

What is the relationship between fractions and rational numbers? Can you explain why the product of two fractions between 0 and 1 is less than either factor? How are rational numbers related to irrational numbers, which your students will study in later grades?

How much do you know… and how much do you need to know?

Helping your upper elementary school students develop a robust understanding of rational numbers requires that you understand this mathematics deeply. But what does that mean?

This book focuses on essential knowledge for teachers about rational numbers. It is organized around four big ideas, supported by multiple smaller, interconnected ideas—essential understandings. Taking you beyond a simple introduction to rational numbers, the book will broaden and deepen your mathematical understanding of one of the most challenging topics for students—and teachers. It will help you engage your students, anticipate their perplexities, avoid pitfalls, and dispel misconceptions. You will also learn to develop appropriate tasks, techniques, and tools for assessing students’ understanding of the topic.

Focus on the ideas that you need to understand thoroughly to teach confidently.

Developing Essential Understanding of Multiplication and Division for Teaching Mathematics in Grades 3-5Move beyond the mathematics you expect your students to learn.

"Unpacking" the ideas related to multiplication and division is a critical step in developing a deeper understanding. To those without specialized training, may of these ideas might appear to be easy to teach. But those who teach in grades 3-5 are aware of their subtleties and complexities.

Developing Essential Understanding of Algebraic Thinking for Teaching Mathematics in Grades 3-5Like algebra at any level, early algebra is a way to explore, analyze, represent, and generalize mathematical ideas and relationships. This book shows that children can and do engage in generalizing about numbers and operations as their mathematical experiences expand. The authors identify and examine five big ideas and associated essential understandings for developing algebraic thinking in grades 3–5.$32.95
Developing Essential Understanding of Geometry and Measurement for Teaching Mathematics in Grades 3–5This book gives teachers of students in grades 3–5 the deep understanding of geometry and measurement that they need to identify and dispel students’ common misconceptions, correct erroneous claims that they make, and move them forward mathematically. It prepares teachers to introduce terms from geometry and measurement in ways that not only bolster students’ vocabulary but also enhance their understanding of concepts and definitions. By helping teachers understand what changes or stays the same when shapes are transformed, the book equips teachers to support and extend students’ understanding of shapes and the space that they occupy.
