Maria Montessori explains the important role that a child's movement plays for their development and growth. As the child grows, especially when he is able to walk and therefore has freer hands, he begins to discover the world through movement and exploration: he opens and closes drawers, takes objects and uses his hands as a means of communication. However, as the author explains, the situation usually arises that parents and educators give more importance to language, focusing on the first babbling, first words or phrases. However, the other great evolutionary advance, the movement of the hand, goes unnoticed when it is, in reality, one of the first tools that the child has to know his environment and the people around him. Thanks to these pages, both parents and educators will understand the importance of encouraging children to use their hands and body through techniques and exercises that will help with their healthy development, especially in a hyper-technological world like the one we live in today. present.
