This study aims to improve the memory, attention, gross motor skills and social adaptation ability of children aged 5 to 6 years. Taking physical games as the intervention method, it explores the effects of physical games on promoting young children's memory, attention, gross motor skills and social adaptation ability, and analyzes the approaches and mechanisms through which physical games enhance these abilities among children aged 4 to 6 years. The game scheme will be timely adjusted according to feedback obtained from a semester-long intervention. Finally, in collaboration with kindergarten teachers and the research team, a set of classroom-based physical game programs suitable for children aged 4 to 6 will be developed, so as to provide theoretical references and practical approaches for the improvement of the above abilities in preschool children of this age group. Smart physical game equipment is adopted and integrated into children's daily physical game classes to record and store children's sports data, establish individual archives of children's motor abilities, and realize real-time uploading, analysis and sharing of sports test results, enabling parents and teachers to keep abreast of children's physical exercise and motor development status in a timely manner.
