Kinaaldá: A Navajo Girl Grows Up by Monty Roessel is a story about thirteen-year-old Celinda McKelvey who is getting ready for her Kinaaldá, which is a coming-of-age ceremony for Navajo Girls. During the ceremony, she challenges her strength and endurance as she works side by side with family members and takes us through the events that happen in the ceremony which includes making a Navajo cake. It also includes Navajo oral stories about the first Kinaaldá. This book is important because Navajo sash represents a transition into womanhood for Navajo girls. The sash is one of the items that the girl wears during the ceremony. I will read this book to the students to help them understand the importance of Navajo sash to Navajo girls.22

Math is a Verb: Activities and Lessons from Culture Around the World by Jim Barta, Ron Eglash, and Cathy Barkley is a great resource for incorporating culture into mathematics. In many cultures, math is something they do as an intrinsic part of their everyday lives. 23 In this book, there are lessons that integrate culture and math that meet common core objectives.
