The gender gap is a systemic inequality between men and women in various areas of society, such as employment, education, and political participation. It manifests in pay differentials, limited access to career opportunities, and cultural stereotypes. Gender equality, one of the goals of the 2030 Agenda for Sustainable Development, requires special attention to the role of design in improving the current situation.

This paper presents the results of practical research in product design, focusing on gender education in early childhood. The study explores feasible solutions to raise awareness, particularly among younger generations, by educating children toward a more respectful and equitable society. The research and development process followed these key phases:
(1) analysis of the current situation and examination of how a child's environment influences and shapes their attitudes, thoughts, and beliefs;
(2) consultation with educators, teachers, and psychologists;
(3) definition of the brief and concept development; and
(4) iterative prototyping and testing.

Practical research is a fundamental phase of the project, as is the exchange of information and experiences between professionals in the field, including teachers, educators, and psychologists. This paper, therefore, discusses the main findings of this phase, based on online surveys, interviews, and field tests.

The study highlights the role of play as an educational tool and establishes key principles and guidelines—developed in consultation with professionals—that are necessary to foster a child's development free from bias and prejudice. Adapted to different stages of childhood, the game aims to teach diversity, mutual respect, and continuous learning. The system consists of three distinct and progressively advanced components that a child can engage with from the earliest months of life. The game was implemented in various educational and informal settings to assess its effectiveness and appeal to young audiences. Addressing a complex issue such as gender education also proves to be an educational experience for young designers, who engage in an interdisciplinary approach that enables them to contribute to the development of individuals who are more open-minded, sensitive, and aware of the importance of mutual respect.
