It is pointed out in the outline that in order to be closer to children's lives, choosing issues that children are interested in will help to broaden children's experience and horizons. Sending away autumn and welcoming winter, leaves turn yellow and pieces of leaves fall from trees. There are many landscape trees in front of our school, such as French phoenix tree and various locust trees. Leaves fall like butterflies. When we are outdoors, we often see children chasing flying leaves and looking around with the picked leaves in their hands, reluctant to throw them away. Some children use them as fans, others as umbrellas. A child ran up to me and asked, "Teacher. You can't see leaves in winter. " No, you can still see leaves in winter, and the leaves on some trees will not fall off. "Another child said," What are those leaves? " "I don't know what is the leaf? "Combined with children's conversation and interest in problems, I conducted a talk on" What leaves can I see in winter ".Through discussion and research, I satisfied children's curiosity and stimulated their interest in active exploration.

2, the focus and difficulty of the activity

According to the requirements of teaching and children's experience, I think the focus of this activity is: let children know which leaves they can see in winter? Difficulties: Know the names of several leaves and the reasons why they don't fall.

Using children's interest in conversation activities, children can observe and discover the changes of leaves in nature, and through the display of courseware pictures, children can learn more about the changes of leaves in winter, thus effectively breaking through the difficulties of activities.
