Language field: story teaching activity design example: the teacher shows a picture of a rabbit's tooth extraction, guides the children to observe the picture carefully, and lets the children guess the reason for the rabbit's tooth extraction. Through observation and communication, children can know that the rabbit pulled out its teeth because it didn't protect the teeth well, which led to the decay of the teeth and had to be pulled out. How did the rabbit's teeth get sick? The teacher led out the story of "Little Rabbit Pulling Teeth".
