This application is the result of research that has been developed within the scope of the Postgraduate Program in Science and Mathematics Education at the Federal Institute of Espírito Santo. Despite the reference to the Golden Material developed by the Italian educator Maria Montessori, it advances, as it makes it possible to work with different numerical bases, grouping, ungrouping and regrouping pieces. The objective is to contribute to the teaching and learning of concepts related to numbers, arithmetic operations and, in this version, also visualizations. The application's proposal is to enrich educational practices already carried out with manipulative materials in the early years of Elementary School, offering an alternative or complement to these educational resources. Its use is recommended based on problematizations proposed by teachers, allowing students to explore, experiment with possibilities, and thus be able to give new meaning to learning experiences.
