Katherine Hannigan

Katherine Hannigan, author/illustrator of the picture book Dirt + Water = Mud, as well as the New York Times bestseller Ida B and 2016 Iowa Children's Choice Award nominee True (...Sort Of), will be presenting at the ICTM/ISTS Annual Conference October 10, 2016.

Dirt +Water = Mud presents, in words and pictures, the always creative and sometimes muddy adventures of a girl and her dog. The two rely on a minimum of props and lots of imagination for their escapades. And the entire story is narrated using word equations (there are also number and picture equations, and a map with a key that uses equivalents).

At the conference, Hannigan will describe the process of creating Dirt + Water = Mud, her experiences teaching mathematics effectively, and multiple, specific ways to integrate equations across the elementary curriculum (including in science, language arts, history, and art) in order to enhance learning and increase fun.

Hannigan will also be presenting with Barbara Ehlers, Associate Professor of Education at Upper Iowa University. Ehlers will be discussing how she used Dirt + Water = Mud as a starting point for a lesson on equations and soil processes in the environmental science class she teaches at UIU, entitled "Environmental Issues Instruction:  Agriculture and Climate Change: Issues and Actions."

Before becoming an author/illustrator, Hannigan earned a B.S. in Elementary Education/Secondary Mathematics. She worked as the education coordinator for a large Head Start program in New York, and as an assistant professor in the College of Design at Iowa State University. She holds a B.F.A in painting and an M.F.A in studio art, as well.
