When I first opened this book, I remember thinking, “How will this book about math games and puzzles be different from the countless other resources on the topic?” Only a few pages in, I re- alized that Well Played is very different. This is a book about math games and puzzles, but it is also a book about building communi- ties of mathematicians who work together to problem solve, talk about math, and figure things out. This is a book full of thought- OREWORD ful and well-chosen games and puzzles, but it is also a book that offers a lens into how we might include this kind of play in our own classrooms in ways that are deeply meaningful and engaging for our students. It is a book truly rooted in the realities and pos- sibilities of the classroom, which is what makes it such a valuable resource for teachers. Well Played includes games and puzzles that check all the boxes for inclusion in the classroom: simple to learn but mathematically meaningful, with variations that allow for differentiation within the classroom, and nuanced enough to allow students to expand upon and deepen thinking through multiple experiences with the game over time. There are several parts of each game or puzzle’s description to which readers will want to pay special attention. Each game or puzzle’s “How It Looks in the Classroom” section offers a glimpse into a classroom in which the game or puzzle is being in- troduced or played. Going beyond “how to play the game,” these sections offer teachers ideas for launching the game or puzzle in ways that encourage curiosity, collaboration, math talk, and productive struggle. Each “What to Look For” section offers several questions for teachers to consider as they work with students. I can imagine keeping these questions on my clipboard as I observe and con- fer with students as a way of guiding my instructional moves and helping me take useful anecdotal notes on students’ strategies and understandings. Each game or puzzle includes several exit question choices to use for student reflection. These questions offer an opportuni- ty for students to synthesize and solidify understandings, either in the form of productive group discussion or individual jour- naling. The exit questions also offer teachers the opportunity to Well Played: Building Mathematical Thinking Through Number Games and Puzzles, Grades K-2 by Linda Dacey, Karen Gartland, and Jayne Bamford Lynch.

Carefully chosen student work examples provide a reference point for teachers as they analyze and respond to student thinking. One of my favorite games in this book is “Yahoo! 100,” from Chapter 5: Addi- tion. Too often math games focused on computation emphasize rote procedural practice over sense-making and thoughtful use of strategies. This game is dif- ferent. In “Yahoo! 100,” students turn over cards, adding multiples of ten and single-digit numbers. The goal is to get the greatest number of cards with a sum less than or equal to 100. This game supports students’ development of efficient mental math strategies for addition, but it also focuses on building number sense as students consider their sum’s distance from 100 and whether it makes sense to flip another card. Additionally, the authors’ purposeful decision to include only cards that are multiples of ten or single-digit numbers allows students to devel- op addition strategies based on an understanding of decomposing numbers by place value. Well Played also acknowledges the powerful potential of online math play, offering suggestions for games, puzzles, and apps at the end of each chapter. Though many online games focus on skill-and-drill and fluency practice, the au- thors have chosen games and puzzles that emphasize problem solving and offer students opportunities to model with mathematics. While this book will be a prized resource of classroom teachers, as a blend of professional development and practical resources, this book will also be valued by coaches as they work with teachers to deepen content understanding and guide instructional practices. As I read this book I kept thinking, “I can’t wait to see what students will do with this game!” and “I know a teacher who will love using this puzzle with her class!” My copy of this book will soon be full of sticky notes and dog-eared pages, and a list of people with whom I want to share it. I know teachers will love this book as much as I do—thank you Linda, Karen, and Jayne for writing it!

A CKNOWLEDGMENTS We are deeply indebted to the teachers and students who col- laborated with us during the development of this project. We explored each game and puzzle within a classroom, and teach- er and student insights permeate this book. We are particularly grateful to students for serving as our consumer experts. Their feedback helped us fine-tune our thinking and play more with ways to embed key mathematical ideas into our discussions of the games and puzzles. We are grateful to everyone at Stenhouse, but most particu- larly Toby Gordon, who showed such early faith in us. Her words “Write about what matters most to you” gave us the freedom to explore, reflect, play, and puzzle. And then, of course, she gave us such valuable and timely feedback all along the way. We are also grateful to our outstanding outside reviewer, who probed our thinking with important insights and intriguing questions. Thank you also to Chris Downey, Elizabeth Tripp, and Jay Kilburn for their care and expertise. All of you added greatly to the quality of our work.
