Ratio and Proportion—Research and Teaching in Mathematics Teachers’ Education offers its readers an intellectual adventure where they can acquire invaluable tools to turn teaching ratio and proportion to professionals and school children into an enjoyable experience. Based on in-depth research, it presents a deep, comprehensive view of the topic, focusing on both the mathematical and psychological-didactical aspects of teaching it. The unique teaching model incorporates both theoretical and practical knowledge, allowing instructors to custom-design teacher courses according to their speci?c needs. The book reports on hands-on experience in the college classes plus teachers’ experience in the actual classroom setting. An important feature is the extensive variety of interesting, meaningful authentic activities. While these activities are on a level that will engage pre- and in-service mathematics teachers in training, most can also be utilized in upper elementary and middle school classes. Accompanying the majority of these activities are detailed remarks, explanations, and solutions, along with creative ideas on how to conduct and expand the learning adventure. While primarily written for educators of mathematics teachers, this book can be an invaluable source of information for mathematics teachers of elementary and middle school classes, pre-service teachers, and mathematics education researchers.

# Word Problems Using Ratios and Proportions

Title: Word problems using ratios and proportions/Zella Williams and Rebecca Wingard-Nelson. Description: New York, NY: Enslow Publishing, 2017. | Series: Mastering math word problems | Includes bibliographical references and index.

Ratios and proportions are good ways to break down and understand really big numbers, and the numbers dont get any bigger than they do in outer space. This book brings young mathematicians on a space odyssey that will ultimately end with them gaining a greater understanding of how to solve word problems using ratios and proportionsand they might even learn a little science along the way. A tips section helps break down the problem-solving process into manageable steps designed to build confidence. These steps are repeated in every problem, helping reinforce the concepts and make them second nature.

# A Focus on Ratios and Proportions

This book makes math education research on ratios & proportions readily accessible to pre-and in-service teachers of grades 6-8.

This resource offers a groundbreaking effort to make mathematics education research on ratios and proportions readily accessible and understandable to pre-service and in-service teachers of grades 6-8. Using extensive annotated samples of student work and based on research gathered in the Ongoing Assessment Project (OGAP), A Focus on Ratios and Proportions teaches readers how students develop understanding and fluency involving ratio and proportion concepts. Special features include: -A close focus on student work, including 150+ annotated pieces of student work, to help teachers improve their ability to recognize, assess and monitor their students' errors and misconceptions, as well as their developing conceptual understanding. -A focus on the OGAP Ratios and Proportions Progression, based on research conducted with hundreds of teachers and thousands of pieces of student work. -Sections on how Common Core State Standards for Math (CCSSM) are supported by math education research. -Each chapter includes student work samples and vignettes to illuminate the research, as well as end of chapter Looking Back questions and Instructional Links, which allow teachers to analyze evidence of student thinking and strategies and consider instructional responses. -An accompanying eResource, available online, offers an answer key as well as extensive explanation of the Looking Back questions. Like A Focus on Multiplication and Division and A Focus on Fractions, this book is designed to bridge the gap between what math education researchers know and what teachers need to know in order to better understand evidence in student work and make effective instructional decisions.
