Maria Montessori1 said that playing is the work of the child and games are their tools. Through its practice, play allows the child to move from discovery to discovery, to confront unfamiliar things and tame them, to practise and refine their abilities on various levels: motor, language, cognitive, emotional and social. Play helps to cultivate the child's creativity and to bring out their personality. When a child is engaged in "play", the brain is stimulated, with inter-cerebral neural connections. In short, the more a child plays, the more they develop their learning potential. By playing, they work and foster their cognitive, motor, social and language development, their self-knowledge, their creativity, their problem-solving ability and their memory.
