Book DetailsMSRI Mathematical Circles LibraryVolume: 24; 2019; 281 ppMSC: Primary 00; 97
The people of the Navajo Nation know mathematics education for their children is essential. They were joined by mathematicians familiar with ways to deliver problems and a pedagogy that, through exploration, shows the art, joy and beauty in mathematics. This combined effort produced a series of Navajo Math Circles—interactive mathematical explorations—across the Navajo Reservation.
This book contains the mathematical details of that effort. Between its covers is a thematic rainbow of problem sets that were used in Math Circle sessions on the Reservation. The problem sets are good for puzzling over and exploring the mathematical ideas within. They will help nurture curiosity and confidence in students.
The problems come with suggestions for pacing, for adjusting the problems to be more or less challenging, and for different approaches to solving them. This book is a wonderful resource for any teacher wanting to enrich the mathematical lives of students and for anyone curious about mathematical thinking outside the box.
In the interest of fostering a greater awareness and appreciation of mathematics and its connections to other disciplines and everyday life, MSRI and the AMS are publishing books in the Mathematical Circles Library series as a service to young people, their parents and teachers, and the mathematics profession.
Titles in this series are copublished with the Mathematical Sciences Research Institute (MSRI).
ReadershipOrganizers and participants of mathematical circles and other extracurriculum activities.

The people of the Navajo Nation understand that mathematics plays a key role in education. Their passion for educating their children about mathematics takes many avenues through application problems, pedagogy, arts, and the joy and beauty of mathematics. The effort of the community has produced an eyeopening series of Navajo Math Circles that are rich with interactive selfdiscovery projects for students used across the entire Navajo Reservation. This book is filled with great problems and shows the creativity not only in the making of the problems but the quality and different approaches of the solutions. They are challenging, but they lead the students to exchange ideas with other students, promote collaboration, critical thinking skills, make connections between mathematical topics, and make friendships.
