| Abstract | Sequences are an important topic--not only in mathematics but also in the mathematics curriculum. Exploring sequences related to medial triangles offers learners opportunities to solve problems involving sequences within geometric contexts. Sequences related to medial triangles are also a rich source of beautiful and interesting geometric patterns that can be discovered with the use of dynamic geometry software (DGS) such as GeoGebra or Web Sketchpad. In addition, exploring sequences with DGS allows learners to formulate and test conjectures, an important mathematical process. In this article, the author describes how his students used GeoGebra and geometric reasoning to visualize, discover, formulate, and test conjectures related to sequences of medial triangles. Students were also engaged in the process of proving the conjectures. (ERIC). |
