Before the theme of "Mysterious Cave" was launched, we made a serious and in-depth study on every teaching activity of the theme, tried to find the mutual penetration point between teaching activities and games, initially determined the content of games to be carried out, and constantly guided children to produce new game themes during the development of theme activities. After the theme activity of "Mysterious Cave", the children were attracted by the ubiquitous caves. They have super imitation and creativity. When they have some experience of caves, they don't feel that the game is permeated with relevant knowledge. For example, in the teaching activity of "sharing cave meals", He Jianuo saw the remaining cave food packaging bags and said to us, "Teacher, put these bags in the supermarket, and we can also buy cave food by playing games." After listening to his suggestion, all the other children agreed. We established Dongdong Supermarket with the children. After playing once, Zhang Canni put forward new suggestions when commenting on the game. She said, "Dongdong food is just packaging. Unlike it, it should be more like putting things in it!" So we collect all kinds of materials that can be used to make cave food with children, including waste paper drawn by children, moon cake boxes collected by children, all kinds of useless advertising paper and so on. Where is the food processing factory suitable? I threw them a difficult problem and the children responded positively. Some say it is better to open a food processing factory in the back, while others think it is better to open a food processing factory next to the supermarket, so that the coolie can cook what food he needs immediately, so there is another food processing factory next to the supermarket. In the processing factory, at first we provided them with templates for making cookies, and gradually we encouraged the children to design their own hole cookies. Although the cookies designed by the children are not very good, they still like them very much. At the same time, in the snack shop, a big tasting activity of snacks with holes is going on vigorously. They use plasticine, fruit packaging bags, hole vegetables printed by children, fruit patterns and other materials to make various hole cookies and snacks to attract guests, such as string with holes, lotus root jambalaya and so on. The business of the dim sum shop became extremely hot for a time. For another example, after the "drinking hole" teaching activity was carried out, children became interested in sewers. On the construction site, the masters spontaneously posted the pictures of Adventures in Sewers on the blackboard in front, and built their own sewers according to the above pictures. They built a long bifurcated sewer with building blocks. When they need to add materials, I encourage them to find them themselves. They found all kinds of boxes from the supermarket and started the sink, toilet, washing machine and so on. Let's build houses, grass and small trees together, and carry out the sewer adventure to the end. After carrying out teaching activities such as Cave of Singing, Clairvoyance and Hole in the Face, the children set up a creative studio processing factory in the science area. They sent their masks, binoculars, magic flutes and bagpipes to the art counter of Xinxin Flower Shop for display and trading, which also attracted the attention of many small customers.
