Is The 'What & How' We Teach Math All Wrong?

Drew Perkins welcomes back Ted Dintersmith to discuss the urgent need to move away from an education system obsessed with standardized testing and toward one that empowers students to do real, meaningful work. In his new book, Aftermath , and documentary, Multiple Choice, Dintersmith argues that our current system is "perfectly designed" to produce results that are increasingly irrelevant in an age of AI and automation.

A significant portion of this conversation focuses on Ted's critique of the traditional math "treadmill." Drawing from his new book, Ted explores the "What and How" of teaching math. He argues that the current "What"—a heavy focus on symbolic manipulation and rote procedures—is largely obsolete. Regarding the "How," Ted shares inspiring examples of teachers who have moved toward Project-Based Learning kind of instruction. He describes classrooms where math is taught through real-world applications—like analyzing local economic trends—where learning happens through trial, error, and collaborative inquiry. By centering math on student agency, Ted argues we can move from "math trauma" to empowering students to solve complex, non-routine problems.
