Abstract
Objective: Describe, through scientific evidence, the process of implementation of the National Curricular Common Base (BNCC) in preschool. Literature Review: Not only the construction and implementation of guiding documents determine the quality of Brazilian education. The teacher must also review his role as mediator of knowledge by means of an innovative pedagogical practice, which consists of working the reality experienced by his students and conducting countless researches in search of a better teaching method. Final considerations: More than the elaboration of a guiding document, teaching in Brazil needs to be worked in a unified way, but at the same time, compatible with the reality and individuality of each student, or at least of each municipality. Thus, making the experiences of each student are a starting point for the teaching-learning process. In this way, building a meaningful learning for students and, consequently, increasing the quality of teaching in Brazil.
