**JAMIE YORK PRESS has two Youtube Channels on Waldorf Mathematics and Meaningfulmath.**

We list the newest videos from Jamie York first, but scroll down for others in our series.

**In our NEWEST VIDEO**, Jamie York compares how a mainstream textbook presents the Pythagorean Theorem, and then outlines how he introduces it, the Waldorf math way. The video includes a proof of the theorem that he uses with 10th grade students.

Jamie York’s concluding remarks about the **CRISIS IN MATH EDUCATION (and transforming blind procedures into meaningful math) ** given during his talk to a capacity audience at the first **MidSchoolMath conference in Santa Fe, NM, March 2014**, where he was a presenter. **CLICK HERE** to see the video.

**PERFECT NUMBERS**. An excerpt from the same talk given in Santa Fe NM, March 2014 on the wonders of perfect numbers, and what they are.

On the **Waldorf Mathematics Channel** you can view complete lectures by Jamie York that have been edited into segments. On **Meaningfulmath**, you can view short excerpts from Jamie York’s talks. On our Waldorf Mathematics Channel, watch, among others:

**1. What is Waldorf Math?**

**2. Jamie York on Waldorf Geometry.**

**3. Math and Music. (An interactive lecture about a Main Lesson taught by Jamie York in Waldorf high school.)**

What is the mathematics behind music? What is Pythagorean tuning? How do harmonics really work? What does it mean to say that frequency is measured in hertz? Why is the piano tuned the way it is? What are the pros and cons of the equitempered scale?
