The wide sign chances, through the networks of motor communications, reveal processes for decision-making with playful meaning. A physical education experience was described according to a sequence based on five motor games, corresponding to five networks of motor communications, with the purpose of revealing the signs to interpret a fully comprehension of playful communication. A total of 180 high school students were part of this pedagogic experience. Events (conducts) were obtained through the systematic observation of three game conducts, to be compared through the five games and thus offer indicators of motor complexity regarding decoding (low, medium, and high coding). Through the game sequencing studied, three blocks with different networks of motor communications were shown: their exclusivity and stability, the instability, and the ambivalence, and the signs to built the opposition, reidentification, and relativization, were inferred. It was proposed that these signs be transferred to a significant pedagogy with curricular interest for the physical education class.
