Abstract

In this article, we describe a lesson that enabled 10th and 11th grade students to create an analog clock using GeoGebra. This self-directed, exploratory lesson is built on students’ prior knowledge of complex numbers and vector transformation and relies on the technological features of GeoGebra.
