The purpose of this study is to examine the Web 2.0-supported activity practices of rural classroom teachers in mathematics lessons. Data were obtained through interviews and researcher diary. The data were analysed by content and document analysis. It was found that classroom teachers working in rural areas benefited from the internet and technological devices in Web 2.0 supported mathematics activity applications; however, it was determined that they lacked Web 2.0 knowledge, the lack of interactive whiteboards in the classrooms and time management problems were factors that negatively affected the implementation process. Rural teachers are recommended to benefit from professional development activities.
