When children move from middle class to large class, facing new teachers, new environment and some new companions, a question arises at the historic moment: "Teacher, our classroom is different from before. Where do I put my toys? " "Where can I buy paper and scissors?" So the theme activity around "our first class" began. During the activity, I provided children with more opportunities for independent activities, and the children produced a lot of valuable theme content. How many things are there in our class is one of them. Activity goal: 1. Learn to use the existing mathematical experience to record, try to solve simple problems in life with simple mathematical methods, and initially perceive statistical methods. 2. Try to cooperate with peers, experience the success and joy brought by cooperation, and initially accumulate a feeling that everyone is indispensable. Activity preparation: notebook, pen, several; Four sets of badges for grapes, apples, bananas and strawberries, small pictures of various items, and glue. Several activities: First, try for the first time. 2. Explain and record the task: "Everyone chooses a badge, and the same badge is a group, and a group of children need to complete the task assigned by the teacher together." 3, children in groups of three, cooperation records. The teacher recorded the children's performance in the activity with a digital camera. 2. Exchange and share experiences. The teacher simply summed up: A group of children should have something to do, some should count, some should remember, and if they can't draw, they can also choose the small picture provided by the teacher. Three: Explore again and try 1. The teacher provided the children with recording paper again. The children are still in the original quartet. Try to record it again. 2. Teachers tour to remind children that they can learn from their peers who have just recorded and cooperate with each other. Four: Extension activists: "We can write down many things in the classroom, and there are many things in the kindergarten. Can you write it down? " Let the children combine freely and record other things in kindergarten in the way they have learned.
