Attention to diversity is one of the challenges that teachers face in today's education. To address the individual differences between students, cooperative learning is of great importance. Contests are a playful way to generate knowledge since they allow experimentation, testing, researching, creating, recreating and socializing. For the teacher, the game enables observation, attention to diversity, and allows evaluation in all its dimensions. Based on the aforementioned aspects, the Venezuelan Association of Chemistry Olympiads (AVOQUIM) designs and organizes the Contest "Know the Periodic Table". This contest proposes playful and experimental strategies to overcome some problems in the teaching and learning of chemistry that have been detected during the evaluation of tests of the Venezuelan Chemistry Olympiad, namely: - Chemical language. - Linking the micro world with the macro. - Experimental activities are not carried out in the schools, due to lack of resources and/or laboratories. - Logical-mathematical analysis and the application of calculations in solving chemical problems. It was determined that the content of the Periodic Table was not addressed despite being included in the curricula at the middle and high school levels and in the last grades of primary school. The contest is carried out annually in different cities of Venezuela. AVOQUIM incorporates into the activities elements from each region's identity, such as the gastronomy, fauna and flora, and the folklore of the host region. The participation in the contest is by teams composed of one teacher and three students one of 3rd, 4th and 5th year of secondary school.
