David Purpura, professor of human development and family science in Purdue University’s College of Health and Human Sciences, has devoted much of his career to creating lasting change in children’s understanding of math. By understanding the mechanisms that have demonstratable impacts on children’s early math learning, Purpura and his research team have tailored their findings into the development of math-focused children’s books, including the “Little Elephants’ Big Adventures” series, the “Pattern Pals” series, and the upcoming “Our Mathematical World” series. The books not only offer an opportunity for young children to learn math but also offer a tool that teachers and family members can use to support young children’s learning.
