Mary Hynes-Berry, PhD, has more than 40 years of experience teaching through oral storytelling while working directly with young children. Her original focus was literacy, but she soon began to find ways to weave in mathematics as she worked with preservice and in-service early childhood professionals. Mary is a faculty member at Erikson Institute in Chicago and a founding member of Erikson Institute's Early Math Collaborative, which provides professional development and carries out applied research on foundational math in early childhood. She is the author of Don't Leave the Story in the Book: Using Literature to Guide Inquiry in Early Childhood Classrooms (Teachers College Press, 2012) and a contributing author of Big Ideas of Early Mathematics: What Teachers of Young Children Need to Know (Pearson, 2014) and Growing Mathematical Minds: Conversations Between Developmental Psychologists and Early Childhood Teachers (Routledge, 2019).
