Card game: a proposal for solving equations in the seventh grade of elementary school
Algebra teaching; educational games; first-degree equations; Middle School; group work.
This study aims to present an investigation into the development and use of a card game designed as a teaching resource for basic education mathematics teachers. The primary goal was to mediate the practice and consolidation of first-degree equations in a 7th-grade class of Middle School. This qualitative research articulates a theoretical investigation plan with a developmental framework that includes both material creation and field research. The theoretical assumptions are grounded in Vygotsky's perspective, which views games as mediation tools where peer interaction and teacher guidance enhance learning and the internalization of concepts. The research was organized into two phases: an initial diagnostic assessment to identify how students solve equations, and an intervention phase involving the classroom application of "LudEk," a card game specifically developed for equation solving. Data collection was conducted through observations, written records, and recordings. The resulting educational product is an algebraic deck featuring equations and solutions, inspired by well-known games, allowing students to solve equations strategically and interactively
