Acknowledgments

Teaching is a collaborative endeavor. We would never have accomplished everything that we've done – including writing this book – without the help of many individuals. We thank all of the people mentioned here. They've made us not just into better teachers but also into better people.

Several current and former administrators at Bayside High School have provided coaching and professional growth opportunities over the years: Michael Athy, Madeline Belfi‐Galvin, Harris Sarney, Susan Sladowski, and Judith Tarlo. Our colleagues in Bayside's Math Department have been a constant source of camaraderie, laughter, and valuable (if sometimes heated) pedagogical discussions. The thousands of students that we've taught at Bayside inspire and challenge us, giving us something to look forward to every day we go to work.

Math for America has created an active, supportive community that trusts and celebrates educators' expertise. Many of our ideas were refined in Math for America's professional development sessions.

Larry Ferlazzo and Katie Hull Sypnieski have been meticulous editors whose frequent questions about our thinking have improved our writing and teaching. Their timely and thought‐provoking edits have made this book much better than it would have been without them. David Powell has done an amazing job of formatting our manuscript. His attention to detail is amazing. Pete Gaughan at Wiley and Amy Fandrei at Jossey‐Bass patiently guided us through the stressful process of producing this book.

Bayside High School students Safi Ansari, Stefany Flores, Emily Hermida, Hana Ho, Anna Ling, Anyu Loh, Camila Palmada, Hardeep Singh, Navneet Sohal, Jason Sun, Ariana Verbanac, Richard Xing, and Joy Zou contributed their work for this book. Susie Xu and Justin Zhuo helped us proofread the figures and tables in this book.

Finally, our spouses and children deserve special mention for tolerating our many early‐morning and late‐night conversations about this book and helping us keep things in perspective.

Bobson Wong: Larisa Bukalov has been a mentor, colleague, and friend for 13 years. Prof. Charles Cohen, Sherrill Mirsky, Dr. Carol Nash, Barbara Rockow, and Prof. Robert C.‐H. Shell were some of the many educators that I've met over the years that taught me the patience and attention to detail that I needed to write this book. The people that I've met online at #MTBoS and #ITeachMath have influenced and encouraged me. Robert Lebowitz has been a source of mathematical and philosophical conversation for decades; without him, this book would not be possible.

Larisa Bukalov: Bobson Wong has been a colleague and a friend. Thank you for putting my ideas about teaching mathematics in writing and always motivating me to do more. Mary Chiesi hasn't just been my co‐teacher but also a mentor and best friend. We developed and practiced many of the strategies in this book together. Dr. Alice Artzt and the faculty at the mathematics education program at Queens College provided countless hours of debates on constructivism, hands‐on approach, teaching mathematics as a language, group work, as well as advice on this book's structure and organization. Twenty years after graduation, I know that I can always count on her help and advice. Dr. Nick Metas at Queens College was famous for his attention to detail. A history buff, he shared stories about mathematicians and helped introduce to me the idea of culturally relevant mathematics. My husband, Boris Bukalov, a math and science teacher, checked the math in the book. My late grandfather, Izaya Vayzman, taught me to love mathematics and teaching. Many of the ideas described in this book came from my watching his everyday interactions with students back in the Soviet Union.

Letter from the Editors

We don't teach math, and we don't know much math, either.

We do, however, know pedagogy.

And there's more great pedagogy in Bobson's and Larisa's book than you can shake a stick at.

In fact, there's so much exceptional teaching advice in this book that any teacher – no matter what subject he/she teaches – can learn a great deal of information from this book about effective instructional strategies that can be used in any classroom.

We sure did!

And, because we have so much confidence in Bobson and Larisa, we're sure all the math is great, too.

If you don't believe us, just check out all the math people who have said so many terrific things about The Math Teacher's Toolbox – their endorsements can be found in the front of the book.

We're thrilled and honored that Bobson and Larisa's book follows our The ELL Teacher's Toolbox in the Toolbox series.

It was a pleasure working with them during the 12 months they spent writing it, and we'd wager this won't be the last book you see written by them.

Introduction

When people find out what we do for a living, they often admit to us that they hate math or they're not good at it. After repeated negative experiences, many develop math anxiety—feelings of fear and tension when doing math (Namkung, Peng, & Lin, 2019, p. 482; Shields, 2007, p. 56). Math anxiety is not simply a set of emotions but a physiological response that affects heart rate and neural activity (Ramirez, Shaw, & Maloney, 2018, p. 145). It can be even more problematic when teachers or parents have it, since they can pass it on to students, which can negatively affect academic achievement (Beilock, Gunderson, Ramirez, & Levine, 2010, p. 1,862; Maloney, Ramirez, Gunderson, Levine, & Beilock, 2015, p. 1,485; Ramirez, Hooper, Kersting, Ferguson, & Yeager, 2018, p. 8).

Unfortunately, math anxiety is common among students, their parents, and teachers. We wrote this book not just to help people overcome math anxiety but also to help them appreciate and use math in the real world. The strategies described in this book reflect techniques and methods that we've used during our combined 35 years of teaching 26,000 lessons to over 5,000 students (including English Language Learners and students with learning differences) from around the world. Many of these strategies rely on social‐emotional learning (SEL, sometimes called social and emotional learning), the process by which people develop the skills necessary to manage their emotions, show empathy for others, and maintain positive relationships with others (Collaborative for Academic, Social, and Emotional Learning [CASEL], n.d.). SEL is a critical part of effective teaching because students' mindsets can affect their cognitive processing. People who experience success in an activity may be motivated and able to learn, while those who experience failure may tend to withdraw, rendering even the most engaging and well‐planned lesson useless (Sousa, 2017, p. 61).

Our Beliefs about Teaching Math

What we write in this book reflects four of our core beliefs about math, pedagogy, and students:

  1. Students need to feel safe before they can learn. Research indicates that when the brain perceives a threat, it instinctively releases adrenaline, which inhibits cognitive functions and other activity viewed as unnecessary (Sousa, 2017, p. 50). Students need to feel safe before they can be receptive to learning. As a result, teaching strategies that make students feel positively about learning can improve student motivation. As we explain in Chapter 11: Building a Productive Classroom Environment, feeling good or safe doesn't guarantee that students will absorb new information, but it is a necessary condition for learning.
  2. Math should make sense to students. We believe that math should be taught in a way that makes sense to students. In our opinion, part of the reason why math anxiety is so prevalent is that many see it as a collection of disconnected and confusing “tricks.” By the time students graduate, they should have the confidence and ability to apply mathematical and critical‐thinking skills to real‐world situations (Berry & Larson, 2019, p. 40). As we say in Chapter 3: Teaching Math as a Language, using the language‐acquisition techniques commonly associated with teaching English Language Learners can help make math more accessible to all students. We also believe that constructivism—the idea that students should actively create knowledge by experiencing it and reflecting on it—should be a central part of math instruction.
  3. All students need access to rigorous math. We believe that all students should have access to rigorous math—mathematical learning that includes solving challenging problems and deeper thinking. It abandons outdated notions of the meaning of being good at math—today's powerful calculators have eliminated the need to equate speed and accuracy with mathematical mastery (Devlin, 2019, p. 10; Ruef, 2018). Rigorous math requires both procedural and conceptual understanding (Ben‐Hur, 2006, pp. 7–8; Levin, 2018, p. 273; McCormick, 1997, p. 149; Rittle‐Johnson, Schneider, & Star, 2015, p. 594). It helps students appreciate the beauty of mathematics and apply it to the world around them. Unfortunately, many barriers (such as low expectations and hidden biases among teachers) can restrict students' ability to experience math in a positive way (Berry & Larson, 2019, p. 41). When trying to determine what type of work is appropriate for students, we keep two rules in mind:
    • What works for some students often works for others. Specific strategies (such as using multiple representations or making mathematical connections) designed to help English Language Learners, students with learning differences, or advanced students can frequently benefit all students. We discuss this idea more in Chapter 5: Making Mathematical Connections and Chapter 15: Differentiating for Students with Unique Needs.
    • What works for some students often doesn't work for others. We try to modify instruction to meet the diverse needs of all students (we discuss this more in Chapter 14: Differentiating Instruction). Periodically questioning our attitudes and constantly looking for ways to deepen students' understanding (which we explain more in Chapter 2: Culturally Responsive Teaching) can make us more effective teachers.
  4. Teachers don't have to do everything to succeed. Nobody (including ourselves!) could possibly implement all of the strategies described here at all times. This book should not be used as a checklist of everything that teachers must do to be effective. Instead, we view it as a collection from which teachers can pick what works for their classrooms. We feel that in teaching, as in life, selecting a few things and doing them well is more productive and sustainable than trying to do everything at once.

Structure of This Book

This book is divided into four parts. Part I: Basic Strategies expands on what we believe to be the central ideas necessary to teach math effectively: motivating students, culturally responsive teaching, teaching math as a language, promoting mathematical communication, and making mathematical connections. Part II: How to Plan discusses strategies for units, lessons, homework, tests and quizzes, and grades. Part III: Building Relationships talks about how to build relationships with students, parents, and co‐teachers. Finally, Part IV: Enhancing Lessons contains other important strategies—differentiation, project‐based learning, cooperative learning, formative assessment, and technology.

This book is part of a series in The ELL Teacher's Toolbox (2018a) by Larry Ferlazzo and Katie Hull Sypnieski. All chapters in the books in this series have the following sections:

  • What Is It?: brief description of the strategy
  • Why We Like It: explanation of why we like the strategy
  • Supporting Research: research that supports the strategy
  • Common Core Standards: relevant Common Core content and mathematical practice standards
  • Application: description of ways that the strategy can be implemented
  • Student Handouts and Examples: list of reproducibles and other figures
  • What Could Go Wrong: explanation of what could go wrong with each strategy and what can be done in these situations
  • Technology Connections: links to relevant websites (also available online)
  • Figures: reproducibles, which are also available online at www.wiley.com/go/mathteacherstoolbox

Why Good Math Teaching Matters

The bottom line is that in today's changing world, we need better thinkers and problem‐solvers. We believe that as teachers, we have to do more than just convey mathematical ideas. We also need to be role models for self‐confidence, self‐reflection, critical thinking, and conceptual understanding. What we say and do affects not only the way in which our students learn math but also their beliefs. We hope that this book can inspire you to do more for your students, your communities, and yourselves.
