Card game: a proposal for solving equations in the seventh grade of elementary school

This research investigates how a card game can mediate meaningful learning of first-degree equations in the seventh grade of Elementary School II. Based on the observation of students’ recurring difficulties with algebraic language—such as the use of letters and symbolic abstraction—the development of the card game Equacionando was proposed, which turns the equation-solving process into a playful activity. Grounded in David Ausubel’s theory of meaningful learning and in active methodologies, the study adopts a qualitative research design, using a case study approach with data triangulation. Data will be collected through classroom observations, written records, audio recordings, and questionnaires applied before and after the activity. The educational product consists of a deck of cards with equations and solutions organized into mechanics inspired by well-known games, allowing students to solve equations strategically and interactively. It is expected that the use of the game will contribute to the development of logical reasoning, mental calculation, engagement, and meaning-making of algebraic concepts. The research seeks to suggest alternative and more effective approaches to teaching school algebra, promoting conceptual understanding through the articulation of playful culture, pedagogical practice, and mathematical content.
