The Physical Education class, from an integral physical-educational approach, requires a general vision that contributes to the formation of the child's personality, through the teaching-learning process with a developmental approach. The research corroborates this need from the contents addressed in the classes that first grade children receive. The scientific problem is: How to promote a developmental learning of the contents addressed in the Physical Education Program in first grade children of the "Roberto Reyes Reyes" elementary school? The objective is: To propose developmental didactic tasks for Physical Education classes in the first grade of "Roberto Reyes Reyes Reyes" Elementary School. Theoretical level methods such as analytical-synthetic, inductive-deductive, and empirical level methods such as observation, group interview, document analysis, analysis of the products of the creative activity and experiment with a pre-experimental design are used. The result of the application of the proposal designed by the researcher, allows to obtain through the pre-experimental design, the achievement of a learning process that will allow for the development of a new learning process.
