Episode 85 | Exploding Dots and Student Understanding of Place Value

In May 2018 FPU will graduate the first group of Master’s degree students, who have been scholarshipped by AIMS in the present manner. During the Summer of 2018 we will be hearing from some of them on ZPC.

Chris interviews Sandra Young today. Sandra’s thesis topic was inquiring about the use of Exploding Dots (a technique made popular by Dr. James Tanton and the Global Math Project www.explodingdots.org) to teach or enhance student understanding of the concept of Place Value. She describes her methodology, some findings and her conclusions. Interestingly enough, on top of the concept enhancement she did also notice expressions of enjoyment and joy in doing mathematics in her students; which is the primary focus of the Global Math Project.
