This episode of Room to Grow, Curtis and Joanie reflect back on 2025 and all that they learned during the year. A significant number of 2025 episodes of Room to Grow were focused on the Mathematics Teaching Practices from NCTM’s Principles to Actions, celebrating the 10th anniversary of its publication. Curtis and Joanie highlighted how these practices have survived the test of time, and continue to reflect good teaching in mathematics. Additionally, our hosts preview what new topics they are hoping to learn and explore podcast episodes about in 2026.

Additional referenced content includes:

· NTCM’s Principles to Actions and Taking Action books

· Pam Harris’ website and book

· Julianne Foxworthy Gonzalez, Ph.D. in Mathematics Education. Math guidelines for supporting multi-language learners (MLLs).

All of us at Room to Grow wish you a peaceful holiday season!

In this episode of Room to Grow, Curtis and Joanie reconsider the balance of conceptual understanding and procedural fluency in math instruction. Although this topic has been discussed before, our hosts acknowledge that there is great nuance and many considerations in considering these two ideas in the teaching and learning of mathematics.

Curtis and Joanie discuss how inquiry-based, discovery-style learning opportunities are more open ended, are student centered, and are less teacher directed. They support these types of lessons in math instruction while recognizing that there are times when an explicit approach where teachers are sharing important information also has a place. Additionally, our hosts consider that teaching procedures and algorithms also provides and opportunity to cultivate conceptual understanding. When teachers help student find the conceptual understanding within the procedures, they engage in mathematical reasoning. This type of reasoning through concepts and procedures contributes to a broader and more robust understanding of meaningful mathematics.

This episode of Room to Grow, Curtis and Joanie speak with Pam Harris. Pam is well known and loved for her website, podcast, books, and conference sessions all based on her core belief that “Math is FigureOutAble.” Today’s discussion centers on Pam’s newest publication, Developing Mathematical Reasoning: Avoiding the Traps of Algorithms.

Pam starts with three distortions about math that are common among teachers, students, and the population, and can impact how educators engage students with math in their classrooms. Next the conversation shifts to what is meant by algorithms, and how they differ from strategies and formulas. Then the discussion focuses on the potential traps to learning that can result from teaching algorithms in mathematics. All of these ideas are based on the development of mathematical reasoning, from counting strategies to additive thinking, to multiplicative reasoning and proportional reasoning, then the functional reasoning that comprises much of the math students learn in high school.

There are so many good ideas in this episode that will challenge you and get you thinking!
