In daily life, children often come into contact with mathematical phenomena such as "1" and "many", but children are vague about these mathematical phenomena and can't accurately understand the relationship between "l" and "many", which requires our teachers to consciously guide children to analyze, synthesize and compare things by organizing various forms of perceptual activities, but this kind of teaching must be vivid.

At first, I took out a basket of fruits and guided the children to talk about the differences between these fruits. The children can only tell the colors of these fruits are different, so I took out a small orange and a big orange. Under my guidance, children can tell one orange is big and the other is small. Next, I asked the children to close their eyes. I divide these fruits into two baskets. There is only one fruit in the white basket, and the rest are put in the blue basket. I asked my child to tell me the difference between the two baskets, but the child couldn't answer. I'm just saying that there are several in a white basket, and children can answer one loudly. There isn't much fruit in the blue basket, and the children replied that there is a lot. In fact, I didn't give them enough in this respect. I told my children the answer directly, but it didn't arouse their enthusiasm for learning. In the later operation, I already knew the shortcomings of the first link, so I arranged for nine children to send fruit one by one, so that the children could say that it was changed, and the children must say that it was complete. After sending so much, the children can also say that the fruit has changed. I said how it changed, and the children couldn't express it accurately. So I arranged the nine children one by one, and I touched them. The young child said that the horse sent a fruit, and when he touched his second child, he said that it was a fruit sent by Zhang Jitian. Children can tell that it is the fruit sent by * * when they touch it too much, so I asked how the fruit in this basket became like this. The young children suddenly understood that it was the fruits sent by these children one by one. I asked, "What's wrong with each one?" The children's loud answers have become many, many. Through this activity, I deeply realized that children's garden outing, no matter what kind of activity, should be carried out in the form of games, so that children can play in middle schools and schools, which not only meets the children's needs for games and activity, but also can achieve educational goals well.
