According to the physical and mental characteristics of children in the transitional period, the relationship between children lays a good foundation for children's enrollment and long-term development from the aspects of body, intelligence, morality and beauty. For kindergartens, the main contents of kindergarten teachers' connection work include the following aspects:

(1) Cultivate children's love and yearning for primary school life.

Children's attitudes, views and emotional state towards primary school life are closely related to their adaptation after entering school. Therefore, in the kindergarten stage, we should pay attention to cultivating children's willingness to go to school, their interest and yearning for primary school life, their positive attitude as primary school students, and their opportunities to gain positive emotional experience in primary school life. Therefore, kindergartens should strengthen cooperation with parents and primary schools through various educational activities, so that children can gradually understand primary schools, like primary schools, yearn for primary schools, and finally enter primary schools happily and confidently.

(2) Cultivate children's adaptability to primary school life.

Does the child adapt to the new environment and new interpersonal relationship in primary school after entering school? This has a great influence on their physical and mental health. Cultivate children's social adaptability, especially initiative, independence and interpersonal skills. It is not only related to the quality of life of children after entering school, but also to the quality of their study in primary schools, which is an important part of the connection between young and old. The contents of cultivating children's adaptability to primary school life mainly include: cultivating children's initiative and independence, developing interpersonal skills, and cultivating children's awareness of rules and tasks.

(3) Help children prepare for school.

Kindergartens need to do the following when helping children prepare for learning:

① Cultivate good study habits. Developing good study habits from an early age will benefit children for life. For example, the habit of reading, doing things seriously, listening to the teacher carefully, keeping stationery and books tidy and so on.

② Cultivate good non-intelligence quality. Non-intellectual quality mainly refers to various personality qualities that affect intellectual activities, including cognitive interest, enthusiasm for learning, will and self-confidence. Without good non-intellectual qualities, intelligence cannot grow alone. Therefore, teachers should attach importance to the cultivation of children's non-intellectual quality, pay attention to cultivating children's curiosity, interest in the outside world and enthusiasm for exploration, and cultivate their will to persevere and not be afraid of difficulties. Let children change from passive "want me to learn" to active "I want to learn". Only in this way can children form a confident and positive learning attitude and produce a positive emotional experience of learning pleasure.

③ Develop thinking ability and basic ability. Many parents want their children to study hard after school, so they teach their children pinyin, literacy and arithmetic before school, and even teach them "systematically" with textbooks for the first grade of primary school. This makes the mistake of "primary education", which violates the characteristics of children's physical and mental development and is not conducive to children's development. Kindergartens should resolutely oppose this practice and fundamentally develop children's intelligence, especially the core of intelligence-thinking ability.
