This project is assumed as a space to share knowledge and experiences on the subject: Solving mathematical combinatorial structure problems. Their resolution requires the use of combinatorial reasoning that can be developed early in children if teachers provide learning contexts involving this type of reasoning. Simultaneously, through the resolution of such issues, we intend to invest in enhancing learning contexts to motivate and increase the interest of students in mathematics. Therefore intend to promote work environments that foment the development and diversification of symbolic representations, solving strategies and procedures that lead students
