This book arose from the desire and need to make maths lessons more attractive, interesting and enjoyable for both teachers and students. We are using didactic games as a way of intervening in maths lessons to try to reduce or solve the difficulties that students have in this subject. Our intention is to contribute to a reflection on the teacher's didactic-pedagogical action in order to improve the teaching-learning process in Maths, bringing about more meaningful learning, suggesting games as a teaching strategy that will reduce the existing blockages between the student and this subject, as well as reporting on some classroom experiences.
