Teaching reflection:
It is an important part of kindergarten education to educate children in all aspects step by step. In view of the fact that some children in this class have decayed teeth, I'm going to educate them on tooth care in "Baby Tooth Care" to cultivate their good habit of brushing their teeth in the morning and evening. The focus of this activity is to guide children to master the correct brushing method and know how to protect their teeth with intuitive demonstration and practice; The difficulty lies in understanding the causes of tooth decay and making a breakthrough with the help of the small experiment of soaking eggshells with vinegar. Activities use watching the introduction of "King of Tooth Cavities" to arouse children's thinking, "Why does the king of tooth cavities have tooth decay" and "How does tooth decay form" to guide children to understand the causes of tooth decay; Inspire children to observe their own dental condition, make a good record of dental health, and then discuss how to protect their teeth. Through courseware, practical demonstration and personal practice, children can master the correct method of brushing their teeth, with strong interest and good teaching effect.
