Living Tree of Mathematics: Fractions from Ancient Egypt to Classic China to Modern Japan. What We Can Learn from Their Effective Ways to Work with, Teach, and Learn Fractions
Presented by Vera Sarina
It is a well-documented fact that many students struggle with fractions. Problems in understanding and applying fractions persist into adulthood, with moderate to severe consequences for everyday and occupational decision making. Why is it that fractions present such a difficult topic conceptually and procedurally? Is it because of deficiencies in teachers’ pedagogical content knowledge? Or is the nature of common, nondecimal fractions quite hard to grasp and internalize? And then, what is the nature of fractions anyway? In this presentation, we will look at the history of fractions and fraction operations in the ancient Egyptian and classic Chinese mathematical traditions as well as modern Japanese teaching approaches. These exercises will help us define some effective ways to understand, teach, and learn fractions.

Want to help students generate ideas and make connections among them, facilitate the development of a range of problem-solving strategies, and support a classroom culture that gives every student a way to contribute, while treating math as a creative process? We’ll talk about how Noticing and Wondering can contribute to all of that . . . and more.
