The main objective of this work was to strengthen logical-mathematical thinking through chess as a pedagogical strategy in sixth grade students of the Antonio Nariño la Yopalosa Educational Institution «Nunchía Casanare», based on the shortcomings presented in the exercises of the mathematics classes with topics that address addition and subtraction, due to the rejection and little interest in this area. Taking into account that pedagogical strategies that contribute to meaningful learning should be sought where the student feels the ability to participate in a class of their interest and pleasure without affecting their learning process, according to the basic competency standards established by the MEN, it was decided to involve the game of chess in math classes so that teachers and parents would know its importance for the development of intellectual abilities in students.
