In this paper we describe a case study on how poetry can be used in mathematics lessons as a teaching tool to make students understand complex mathematical concepts. Observations from school practice will be described showing that students in their high-school final year in Petro Kuzmjak school connected mathematical theories with poetry highlighting the mathematical concepts they learned throughout their education. This paper could be useful for educators who would like to introduce pedagogical innovations into their mathematical lessons, but also for a wider audience interested in combining poetry and mathematics in education.
