The purpose of this paper was to provide a theoretical and research-based knowledge on motor games as a means of preserving and promoting physical development. Movement is one of the most basic needs of a child and a way of learning about the world around them. Besides enabling their development, it is a source of happiness and satisfaction. Play is the most natural form of a child's learning and discovering the world around them, and motor games that combine movement and play become the foundation for healthy and harmonious physical development. The motor development of a child is most intense in the first three years of life, as is brain development, so it is crucial to direct the child to activities with as much movement as possible that they will also enjoy. Motor games are the optimal form of learning healthy physical habits and enjoying at the same time, which is why they should be included from an early age. In doing so, the educator should respect the individual characteristics of the child and allow the activity to be carried out in a spontaneous and natural way for the child. The environment should be diverse and challenging as this increases the possibility of the child's motor development. Considering that sedentary lifestyles are increasingly prevalent among children and cause numerous health problems and lower motor ability, motor play becomes the main foundation for healthy and harmonious physical development. It enables the child to develop motor skills, healthy habits, and movement habits that will ultimately make it easier for them to perform daily tasks and efforts. A motor-skilled child becomes a satisfied and fulfilled child who will be better equipped to deal with challenges in the future.
