I think we should consider the following aspects: First, the content of the activity. The "Outline" points out: "Sports activities should respect children's physical growth and development laws and age characteristics, and do not carry out sports training that is not suitable for children." When selecting activity teaching materials, teachers should estimate children's activity ability according to their age characteristics and design activity content reasonably according to local conditions. For example, children in small classes still lack certain abilities in running, jumping and using sports equipment. When designing activities, we should consider more activities suitable for small class children, such as walking, crawling, drilling, etc., mainly in the form of games to avoid sports injuries and psychological burdens caused by excessive exercise or overload. Second, venues and sports equipment. Before each sports activity, the teacher should choose the activity equipment and arrange the activity venue according to the activity content. When choosing sports equipment and arranging sports venues, the most critical link is to check the safety of venues and equipment. If the venue is uneven or too narrow, it will bring inconvenience and danger to children's activities. Before the activity, you must check whether the equipment is damaged and whether the edge contour is clear. In throwing activities, the throwing direction and distance should be arranged reasonably, and the activities of children should be organized well to avoid unnecessary injuries caused by throwing objects. Third, dress.
