First of all, make clear the meaning of mathematics content, so that teachers can set goals and design teaching process accurately.
For example, before, the concept of ranking within 7 was a bit general, and there was no detailed study on the value it contained and what kind of development it could bring to children. Therefore, there is no pertinence in the design activities, some links are designed somehow, and even some links are not designed.
For example, 1, sorting helps to learn counting and count objects one by one in order. The ability to form time or spatial order enumerations in sorting helps count activities. For example, in the process of introducing the background of fruit picking, each kind of fruit should be picked once (a * * *, there are 7 kinds of fruits, and the number of fruits picked each time increases from 1 to 7) to guide children to count. If you don't realize this value, maybe this link may be omitted.
2. Sorting can help children understand the order of books and establish the concept of numerical order. Natural numbers are ordered in natural sequences. Children want to find my 1- 10 order, which is the first value that teachers can realize. However, in the study of this concept, it is necessary to let children have the consciousness of corresponding quantity and number in the process. If you show pictures of six apples, show the number 6 immediately after counting.
3. Sorting can help children understand the abstract concepts of numbers.
Sorting can help children develop reversible, transitive and dual thinking abilities, which is exactly what they need to form abstract thinking. This is because teachers often ignore the value of sorting because they don't understand or understand the meaning represented by these three kinds of thinking. In this respect, I just didn't realize the value contained in it and didn't guide it in the activity. The next section involves various types of sorting, which can also be said to be gradual, but I think this concept should be unknown in quantitative sorting, but it can be infiltrated to let children feel it first.
Second, pay attention to the age characteristics of finishing ability development.
After consulting the books on mathematics, I found that the children in the middle class (4-5 years old) can basically complete the ranking within 5, and some can't. This activity has designed a ranking within 7, which is a bit high. However, through observation, it is found that the development of children in this class can be ranked within 7 at present. Therefore, in the future activity design, I will consider reading reference books first to understand the development of children at corresponding age stages. After asking the old teacher about the possible realistic level of children at present, we should consider the change of the level from simple to difficult and the form of curriculum in the curriculum design to take care of the individual differences of children.
Third, pay attention to the preparation of courseware and the design of teaching AIDS.
Suitable for children's age characteristics, with operability. In this class, the preparation of teaching AIDS is not perfect. In children's vegetable solitaire sorting, children need to connect lines and only give arrows, and no horizontal line is provided in the middle of the arrows, so children are connected with arrows. So in the next design process, we should consider all the details and make the rules clear. Or design a simple action operation, such as cutting the dishes that need to be arranged at the back and letting the children arrange them themselves, because the children can count and know the correct order, but they just don't know how to connect the lines, and the lines are still empty.
Fourthly, try to develop children's mathematics through the mutual infiltration and integration of various fields and regions.
We know the value of the game. In the process of the game, the boredom brought by mathematical abstraction will be transformed into children's initiative. Moreover, in the previous stem learning process, we also noticed that the creation and infiltration of mathematics in the region and life is a process of children's play, but there is not too much integration in the design of various fields, and most of them are made up by teachers themselves. Before, some teachers combined picture books with mathematics, and I also tried to integrate mathematics into sports activities. In the future mathematics teaching process, I will try to integrate art, music and mathematics to make mathematics everywhere.
Fifth, the teaching form.
In terms of teaching form, in the third part of this activity, when doing operation exercises, we designed a group running activity. The operation list was divided into three groups, and the children took turns running the group respectively. However, due to saving materials, we changed the activities to group exercises. The teacher divided the children into two groups according to their seats, and each group operated a task. It is found that the children have not practiced enough, and because the tasks completed by the two groups at the same time are different, it is not conducive to taking care of the individual differences of the children when the teacher evaluates one of the tasks. The next group and group activities will consider the level of materials provided and how to design situations and teaching AIDS to save materials and achieve teaching goals.
Sixth, try to fit the theme situation.
The math situation should be close to the theme activity of this class. In this math class, I designed the fruit picking and classification in Rabbit Orchard. Later, there was an exercise to classify small animals, which had nothing to do with the story situation of rabbit orchard. So I thought of changing it into a fire in the Bunny Orchard, and I needed firefighters, so that the children could queue up to find firefighters in order. This is better, which not only fits the theme of "safety camp" in this class, but also trains children to pay attention to a few things according to the plot atmosphere and operate quickly.
