- Title:
- An Overview of the Usage of Ancient and Contemporary Vigesimal Numeral Systems
- Abstract:
- The modern base-10 decimal system originated during the 1st to 4th century A.D. and remains in place for most cultures. From the 3rd century B.C.E through the 17th Century A.D., the Maya had multiple ways of representing their numerals, one of which is the vigesimal system. In the mid 1990s, the vigesimal system was revamped by a contemporary group of marginalized mathematicians, and is still in use and being researched by universities to this day, but not without facing backlash. This presentation will include the historical context of the vigesimal numeral system within the Pre-Classic, Classic, and Post-Classic Maya periods, the contemporary vigesimal numeral system, and examples of how to perform arithmetic through both of these methods.

- Title:
- From Problems to People: History-Driven Storytelling in Mathematics Teaching
- Abstract:
For the first several millennia of human existence a large component of any education consisted of stories told and heard around a campfire. As a result storytelling as a pedagogical tool is deeply embedded in the human psyche. But it is difficult to convey mathematics via stories so we — or at least our textbooks — have for the most part simply dispensed with this essential pedagogical tool, opting instead for the highly efficient seeming theorem/proof/example approach. Most teachers recognize, at least intuitively, the poverty of this. But how does one embed a given topic, say calculus, into a story while simultaneously maintaining focus on the mathematics to be learned?
It sounds impossible, but it is not.
There are a multitude of interesting and beguiling stories in mathematics. Taken together they make up what Ivor Grattan-Guiness has called our mathematical heritage. They explain why modern mathematics has taken its current form, conceptually, notationally, and culturally and they provide context for the subtle and often non-intuitive ideas and methods our students must master. We have written two textbooks (and we’re working on a third) where we have explicitly used our mathematical heritage as a frame for the topics being taught. In the course of writing these books we found that we could also present the progression of mathematical ideas itself as a story with a beginning, middle, and end. We will discuss our efforts to use story-telling techniques as an effective teaching mode in our textbooks and classrooms without sacrificing the mathematics.
