In the teaching-learning process of Mathematics in Colombian Secondary Basic Education One of the main difficulties presented is related to the development of competencies math. For this reason, the research focuses on its study, in particular of the competences mathematics: reasoning and argumentation; Communication, representation and modeling; Approach and problem solving. To solve the previous problem, a strategy was developed didactics that allows the teacher, through a group of actions and didactic suggestions, to organize and direct the teaching-learning process of Mathematics in these grades, facilitating the development of said competences. The thesis provides the mathematical object, actions, general processes levels of development and performance indicators, which constitute the structure for the development of Mathematical competences in Colombian Secondary Basic Education. The investigation was developed with a mixed approach, supported by the use of qualitative and quantitative methods; in the same way it was applied different instruments for the validation of the didactic strategy, based on the Delphi method and a quasi-experiment of pre-test and post-test with a control group, at the Pedro Educational Institution Vicente Abadía, from the municipality of Guacarí.
