People's psychology is produced and developed in activities. Games are children's lives, and games are activities all day. Besides the educational function of the game itself, the integration of mental health education into the game can also play a synergistic role. Games are an excellent means to cultivate social skills and independence. In practice, we realize that not all games are effective and meaningful for mental health education. Children's mental health education games should be targeted and targeted. We can sum up three principles: the functional principle of the game; Principle of children's needs; The principle of pertinence. According to the three principles, some role games and sports games with mental health education are used flexibly, which solves the contradiction between children's desire to participate in various social life like adults around them and their physical and mental development level. Through games, children can experience the joy of being gregarious, enhance their gregarious consciousness and improve their cooperative ability. In role games, it is undoubtedly meaningful to let children learn how to get along well with their peers, develop self-awareness and gregarious feelings, and coordinate the development of socialization and individuality through activities such as establishing the theme of the game, choosing the role and developing the plot. For example, in the doll's house game, children can play various roles, such as father, mother and child. Teachers can participate in games in a timely manner, guide children to imitate their fathers to buy food, mothers feed their children, and fathers and mothers take their children to the park together, which not only cultivates children's communication skills and cooperative consciousness, but also develops their language and makes them happy. In the game "I found a kitten", children dress up as various small animals to help the mother cat find her children. Under the guidance of the teacher, the "little animals" sent kittens found in different places home and happily told the cat mother where they were found. When the mother cat thanked the little animal, the little animal said happily, you're welcome. Cultivate children's good psychological qualities such as thinking of others, helping others, and being polite to others. Second, integrate mental health education into teaching activities and daily life. Our mental health education is not to add a day's activities, nor to replace the original teaching activities, but to tap the inherent and potential factors of teaching activities, and give better play to the educational role of mental health teaching activities in teaching activities according to children's psychological characteristics and development needs, instead of focusing on the facts and "watering the spring" externally; Nor is it blind to the psychological factors contained in the original materials, regardless of children's psychological reaction, blindly instilling infiltration or separating various teaching activities from each other. Cultivate children's expressive ability consciously in language activities, so that children can express and exchange their feelings and ideas in front of teachers and children; Cultivate children's social skills in music activities; Cultivate children's communication and cooperation ability in artistic activities, and integrate teaching and scientific research with mental health education. In the form of activity organization, the integrated mode is adopted to realize the "running class system" and break the class boundaries. From small, middle and large classes, children participate in activities with each other, from single peers to mixed-age partners, which expands children's communication occasions and opportunities and improves their social skills. Daily life is a time when children's interpersonal communication is frequent and their psychological quality is naturally revealed. Life needs gregarious, and gregarious can be cultivated in life.
