Abstract
This work consisted of the compilation and implementation of school projects at the secondary level, aligned with the principles of the New Mexican School. This educational reform emphasizes placing students and their communities at the center of teaching, promoting a more contextualized and relevant educational approach. Therefore, it is essential to address the issues that students identify in their immediate environment. In response to this need, this document presents two innovative project proposals that address real issues in the State of Colima. These projects aim to link mathematics with other subjects such as sciences (physics, chemistry, and biology) and social sciences (civic and ethics education), without neglecting the student’s integral development, which includes the arts. Both proposals were implemented in two secondary schools, achieving favorable results in the development of mathematical and transversal skills. The integration of various disciplines allowed students not only to acquire academic competencies but also to develop a greater awareness of their social and natural environment. Thus, these initiatives are framed within the vision of forming critical and engaged citizens, while reinforcing fundamental mathematical skills essential for their education and daily lives.
