This article examines the geometric concept of the cone and highlights the significance of interactive teaching methods in mathematics education. A cone is one of the fundamental three-dimensional figures studied in school geometry and plays an important role in developing spatial thinking and problem-solving skills. Traditional teaching methods often limit student participation, whereas interactive approaches encourage active learning, collaboration, and critical thinking. The article discusses the properties, formulas, and practical applications of cones while analyzing how digital tools, group activities, and project-based learning can improve understanding. The study concludes that interactive methodologies significantly enhance students’ motivation and academic achievement.
