There's a brand new book for K-2 teachers! In this episode, Pam and Kim discuss how strategies in early mathematics build upon each other and increase in sophistication for future learning.

Talking Points:

• Strategies build on each other, algorithms do not
• The importance of building relationships and mental actions in students' brains
• Get to Ten grows up to Get to a Friendly Number
• Add Ten grows up to Add a Friendly Number
• How the Over and Give and Take strategies help students think outside the problem
• Ways developing strategies allows for differentiation

In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on October 29, 2025.

Note: It’s more fun if you try to solve the problem, share it on social media, comment on others strategies, before you listen to Pam and Kim’s strategies.

How can we adjust our teaching to meet the needs of our students? In this episode, Pam proposes a series of rapid-fire pedagogical scenarios for Kim to respond to with her best advice. What will Kim say in 90 seconds or less?

Talking Points:

• What to do about a student who only solves addition problems left to right?
• How to handle a student who always signals to pass during Problem Strings?
• Ways to encourage students to use strategies learned in Problem Strings when doing independent math work.
• Managing students who always yell out answers.
• Using Hint Cards/Clue Cards effectively
• Suggestions for students who have additional time accommodations
• The importance of knowing your students

For additional information on Hint Cards, listen to Podcast Episode 38: Multiplication Facts: The Good, the Bad, and the Ugly Pt. 5

Pam and Kim went to NCSM and NCTM in Atlanta! In this episode, they share some of their favorite moments, biggest take-aways, and new insights gleaned from the sessions they attended and the people they met.

Talking Points:

• Discussing the meaning of "algorithm" with Sarah Bush and Karen Karp, authors of The Math Pact
• Importance of talk moves and listening moves, with Elham Kazemi and Allison Hintz, authors of Intentional Talk And Listening
• The joy of celebrating someone else's learning from Vanessa Vakharia
• How the Science of Reading does not correlate or correspond with what the people who call themselves the Science of Math are suggesting
• The importance of Affirming Learning Walks
• Clarifying the meaning of the word "procedural", as in "procedural fluency"
• The misleading nature of much of the math research currently being approved by What Works Clearinghouse
• Shout-out to James Tanton for being intellectually curious!

What role can technology play in mathematics education? In this episode Pam and Kim explore a Problem String for solving systems of equations using Desmos.

Talking Points:

• Graphing systems of equations
• Where lines intersect with different parent functions
• Using graphing to understand the behavior of a cubic function and more
• Using technology as a tool to understand what's happening, not as a crutch just to get answers.
