The use of games within the classroom is in constant growing, however, there are still demands for better solutions to problems such as reconciling leisure with class or the lack of attention of children. This work demonstrates methodologies used to survey and analyze requirements for the development of children's educational games, with the target audience of children from 5 to 9 years old. A list of basic requirements that can improve the development of educational games and provide a basis for further development of a game is raised. It is possible to continue the work by addressing theories of education, the process of gamification of education and other requirements gathering methods.
