The authors decided to create a transdisciplinary science, technology, engineering, art, and mathematics (STEAM) lesson for children focused on Charleston, South Carolina iron-gate artisan Philip Simmons and his work. The lesson taught about the art of Philip Simmons, as well as symbolism, mathematics, the process of 3D printing, and some history of Charleston. The results were some original 3D printed, Simmons-inspired gates that made connections to several disciplines in the curriculum. This article begins with an introduction to the artist and his work, followed by a discussion of culturally relevant pedagogy (CRP) and the importance of inclusion in the classroom. Then the history and nuances of transdisciplinary and STEAM education is examined. The details of the lesson are highlighted, along with a discussion of the outcomes of a transdisciplinary lesson that celebrates the African American artist Philip Simmons.
