2. Observe and perceive the appearance characteristics of various toys, and know the physical marking diagram of toys.
3. Willing to participate in mathematical operation activities and initially feel the fun of the activities.
Activity preparation:
Teaching AIDS: Stick different plastic toys in the class on the floor to mark them.
Learning tools: Mix the plastic toys in the class, and there are several plastic baskets. Children's books.
Activity flow:
One: Where to put the toys.
(1) Show many toys mixed together to guide children to observe and understand: the teacher washed all the toys that everyone played, but they were all mixed up. Guide the children to separate the toys and put the same toys in a basket.
Two: Send toys home.
Children hold toys and put them in the corresponding baskets according to the physical marks. Guide the child to say, "toy baby, I'll take you home."
Three: exhibition activities.
Show the toys in each basket. Teachers and children should check each other and let the children talk about whether the toys are the same as the marks.
The first link is mainly one-to-one correspondence, which is relatively simple. I provide intuitive toys that children are usually exposed to, so children are very interested and enthusiastic about participating in the hands-on activities. Many children hold their hands high, so I let them observe and judge for themselves before putting toys. Compared with the first link, the second link of "sending toys home" is a grouping operation link from shallow to deep, and it is also a link to break through the difficulties in teaching. I divide the content requirements into two interrelated links: "toy classification" and "toy finding home", which are permeated with mathematics education and routine education. According to the abilities and characteristics of each group of children, three or more kinds of mixed toys (including fruits in supermarkets, fruits in structural areas, fruits in living areas and operating areas) are materials that children usually contact, and toy baskets with corresponding marks are provided for children to learn to classify toys according to the marks. Most children can actively participate in the operation process and quickly classify toys. Children with outstanding practical ability are Gong Ziru, Zhao, Su and Chen Xinyi. They can correct other children's wrong classification in time and quickly find the corresponding toy cabinet under the guidance of the teacher, but the purpose of some children's operation is not clear. I didn't follow my requirements, such as Shen Jiahui, Si, etc. But after reminding and guiding, I can basically operate correctly. What puzzles me in this link is that in the classification of toys, I find that many children simply classify a toy without classifying multiple toys at the same time, for example; Lu you smiled and saw the snowflake label on the basket in front of him, so he desperately sent the snowflake to the basket.
