The Ministry of National Education has installed interactive whiteboards in classrooms in most schools to enable traditional classroom environments to become more effective and technologically equipped classes of the future. In this context, the opinions of middle school mathematics teachers who are actively involved in the use of interactive whiteboards were examined by taking into consideration the usage of the interactive whiteboard in the teaching of the lessons. The framework of the qualitative research approach was used in the study. Individual interviews were conducted with six middle school mathematics teachers working in a city in Central Anatolia. Themes were obtained through qualitative analysis of interviews, were the interactive whiteboard, mathematics course suitability, teachers' reasons for using this technology, and their difficulties while using this technology, their education, and suggestions. As a result of the analysis, the middle school mathematics teachers stated that they use interactive whiteboards in mathematics courses. Still, they mostly use them in the geometry courses, especially for visualization, attracting student interest and attention. In addition to this, teachers' difficulties and suggestions related to the hardware and instructional experiences about using the whiteboard were included in the research.
