Mathematics is a subject in which students construct a negative social representation, having an impact on their performances. Thus, it becomes important to find a way to stimulate the students and motivate them in learning mathematics. In this sense, the use of games in the classroom allows students get involve in mathematics activities, giving a meaning to mathematical learning. It also allows developing the (mathematical) abilities and competencies that are essential a future citizen. In this investigation, we assumed an interpretative paradigm and an action research design. The participants was a group of children from preschool, 1st graders and the teacher/researcher. The data were collecting through the observation, informal conversations, teacher/researcher’s diary and documents.
