The Lessons

Presented as stories, Marilyn’s signature vignettes describe classroom-tested lessons and reveal both the preparing and planning helpful for instruction, as well as:

  • address a broad range of math content, some focusing on number and operations while others engaging students with geometry, algebraic thinking, probability, and more;
  • provide a detailed look at how lessons unfolded in actual classrooms, including how students responded and examples of students’ written work;
  • are presented in sections to make it easier for you to translate them into your own teaching plans; and
  • describe how to organize instruction to maximize students’ opportunities to verbalize and clarify their ideas and also listen to and learn from each other.

The Audio Segments

Included with the lessons is online access to nine audio segments titled “Conversations with Marilyn.” In each segment, Marilyn, joined by longtime Math Solutions colleague Patty Clark, talks about teaching math. The conversations focus on topics that range from “What Makes a Good Problem?” to “The Meaning of Math Menus.” Consider them your personal conversations, meant to support you further as you plan to use the lessons with your students.

The Reproducibles

When appropriate, lessons include accompanying reproducibles, available in a down­loadable, printable format. For access to the audio segments and reproducibles, visit and use the key code WTMC to register.

Praise for Welcome to Math Class

“For decades, Marilyn Burns has been inspiring teachers and anyone who cares about mathematics teaching and learning. Every time we see or hear Marilyn’s words, we are encouraged to take one more step toward excellence and move ever closer to helping every student become empowered as a mathematical thinker. Marilyn is truly a national treasure, and this collection is yet another wonderful gift from Marilyn to all of us.”

Cathy Seeley

NCTM Past President and author of Faster Isn’t Smarter and Smarter Than We Think

“Having Marilyn’s voice in my ear brings new life and insights to lessons I’ve taught countless times—one of my favorites being Consecutive Sums. Congratulations Marilyn—you continue to be my guiding light through the wonderful world of learning, teaching, and mathematics.”

Brenda Mercado

Early childhood teacher in Tucson, Arizona, and coauthor of Teaching Preschool and Kindergarten Math

“I have loved Marilyn Burns’s work since the moment I started teaching. A favorite of mine has been The Border Problem. I have used it with many levels of students with such rich results. In the past few years, I have used the problem with teachers. It always ends with a rich discussion around the surprise that the lesson began with something simple like a grid and then turned into algebra!”
