Throughout this book, we share the conception of a proposal that aims to contribute to the improvement of the teaching of school geometry, one of the most important areas within mathematics education, which allows to promote and develop reasoning in students.The above, applying technology in an innovative way as one of the fundamental characteristics of the proposal. In addition, one of the chapters presents the educational robot Voldi and narrates the experience that took place during its exploration within the primary educational classrooms in Mexico.On the other hand, there is a brief analysis of the problems that have occurred around mathematics education in Mexico, which has as one of its causes the expansion of mathemaphobia from primary to higher levels. For this reason, the authors of this book join the efforts to generate new playful experiences in mathematics classrooms, which can immerse students in an interactive and dynamic environment that helps to create in them positive experiences related to the teaching of this important educational area.
