The Math We Teach vs. The Math We Need with Ted Dintersmith

Apr 27, 2026

Ted Dintersmith, education advocate, author, and filmmaker who has visited hundreds of schools to rethink learning. He argues that school math often trains skills AI can do and misses real-life relevance. Short takes cover the split between classroom math and practical math, how testing narrows learning, and classroom examples that make probability and problem solving meaningful.

School Intelligence Mirrors What AI Already Does

Schools prioritize a narrow testable intelligence that aligns precisely with what AI does best.
Ted Dintersmith argues decades of standardized testing shaped curricula toward tasks computers can grade and thus perform better than humans.

ANECDOTE

A Math PhD Wrote Aftermath To Rescue Practical Math

Ted describes his math background and why he wrote Aftermath after a New Yorker quote claiming math has one right answer.
His PhD in mathematical modeling and experience in tech led him to highlight modern, applicable math over rote algebra.

INSIGHT

Many High School Math Skills Are Historical Barriers

High school math content used to be essential but no longer translates into real-world thinking for most students.
Dintersmith notes symbolic skills like closed-form integrals were practical pre-computers but now act as barriers to careers.
