This article aims to explore the experiences, perceptions, and pedagogical practices of rural teachers in PDET municipalities in southern Tolima, Colombia, regarding the use of information and communication technologies (ICT) in mathematics teaching. Using a qualitative and interpretive approach, semi-structured interviews and digital questionnaires were applied to analyze how teachers integrate ICT into their educational practices and what factors influence their appropriation. The findings reveal a heterogeneous adoption of digital tools, conditioned by connectivity, technological infrastructure, and teacher training. Nevertheless, innovative and creative practices have emerged to strengthen mathematical thinking in structurally limited contexts. The study highlights the importance of situated teacher training and public policies that respond to the specific characteristics of rural education. It concludes that pedagogical transformation mediated by ICT in these contexts depends not only on access to technological resources but also on the commitment, resilience, and reflective capacity of educators.
