In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on July 9, 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 Problem Strings help build big ideas? In this episode Pam and Kim walk through a Problem String that helps students dig into area and multiplicative equivalence and helps you know how to expertly facilitate.

Talking Points:

• Facilitating the string
• Teacher moves during the string
• Modeling the string
• Equal products means total area is the same
• Why we want students to have lots of experience with concepts rather than just direct teaching.

What if finding equivalence between fractions, decimals, and precents wasn't just a task for students to do, but a tool making them more efficient in rational number computations? In this episode Pam and Kim talk about code switching with rational numbers to make complex problems more figure-out-able.

Talking Points:

• What is code switching in rational numbers?
• A Problem String using equivalence to think about multiplication
• Tasks that use equivalency to solve problems rather than just practicing conversions
