Reflection on the teaching of division and cooperation

10 chapters of the teaching and reflection of the teaching and learning Fan Yiyi:

The division and division of 10 in this lesson, the division and division of 10 for the calculation of subtraction within 10, the addition of subtraction and subtraction within 20, and the further study of recognition and calculation are of great significance.
Guess the number of questions. After class, I showed the envelope, took out a few flowers in the envelope, and let the students guess that there are still a few left in the envelope. The students can only guess without experience. After the students gain some experience, the students can guess the envelope. There are a total of 10 pieces of flowers, and there are a few flower pieces in the envelope that can be used initially, and this leads to today's topic - 10 points and combinations.
Orderly thinking. After learning the division and integration of 2-9, students have accumulated a certain amount of exploration experience. Therefore, in the form of learning and sharing, the students use the form of self-exploration to let students first exchange the 10 beads into two parts to pay attention to, so as to highlight the importance of order, and then let the students divide one point and put 10 points. The beads are coated in a sequence, allowing the students to draw a few of the 10 points.
Hands-on operation. The composition of the cognitive number is the teaching strategy of this unit. All the examples and "try it out" first divide several objects into two parts, then abstract the sub-objects into decomposition numbers, and then combine the numbers from the decomposition numbers. Continuously let students experience the activities of division and integration, feeling that the combination is different and related.
Clever memory. There are some rules in the division and combination of numbers. The discovery and utilization of these laws can improve the efficiency of exploration activities and the level of composition of memory. On the basis of understanding the division and combination of 10, the students showed a dozen children's songs. "1919 good friends, 2828 hands in hand, 3737 are really close, 4664 is going together, 5-5 is made into one "Hands", the child is very interested in the songs, and this song contains "catch ten methods." Help students consolidate the division and integration of memory 10 through the form of children's favorite children's songs.
Consolidate the exercise. Here I introduced a story about "Little Monkey Travel" and set up a three-way practice in the story. Explain the meaning of the question yourself and let the students do it independently. The students' interest in learning is very high. Unconsciously, the students are consciously and skillfully applied according to the understanding of the division and integration of 10. It not only adapts to the lively and active personality characteristics of the first-grade children, but also cultivates students' interest in learning mathematics.
In short, I have handled the teaching materials flexibly during the preparation of the lesson, carefully designed each link, in the teaching, let the students do their own hands, brains, and try to understand, so that students can develop flexible thinking in vivid and lively learning. Sex, also received a better teaching effect.

10 division and cooperation teaching reflection model two:

The knowledge point of the lesson of "10 points and combinations" is which two numbers can be divided into 10 and which two numbers are combined. The teaching of the division and the number of the students is very important for the students to further understand the actual size of the number, the relationship between the number and the number, the meaning of the infiltration plus and minus methods, and the basic calculation method of the addition and subtraction within 10 degrees. This part of teaching can help students to initially establish the idea of ​​separation and integration. The initial experience of differentiation and differentiation is dialectical, which is the unity of opposites. The 10 points and the combination, the textbook uses the beads that the students are familiar with as the theme, let the students paint in an orderly manner, divide each string of 10 beads into two parts, and then get 10 different compositions according to each method, and One statement associates with another. Compared with the previous teaching content, the 10 points and combinations improve the teaching requirements. First of all, the textbooks do not provide examples, allowing students to manipulate, explore, and acquire knowledge. Secondly, students are required to carry out the ordering and division of 10 in an orderly manner, and ask for two kinds of arguments through one picture. In response to the psychological development characteristics of first-year students, I arranged the game of “guessing the ball” at the beginning of the course. Through the game students, they have a great interest in the mystery of the guessing ball. Then, put 10 beads in order, and divide the scores so that the students can get 10 points and combinations. Then the number of the two flowers together is 10, the magic bottle, the train, the small accountant, the friend and other lively game forms, let the students participate in the consolidation of the knowledge. Let students experience the joy of learning and enhance the self-confidence of learning.
The most important feature of the 10 division and the division is that the students' self-exploration is in the mathematical activities. The whole class begins with the game of guessing the ball, allowing the students to “grab the catch” and “count the number” and then the teacher guesses that several beads have been caught and raised mathematics questions, which not only stimulates the students’ interest in learning mathematics, but also makes the students feel the initial feelings. To the close relationship between mathematics and life; in the development stage, through the operation of learning tools, painting team-to-bead cooperation activities, independent exploration and discovery of 10 points and cooperation, to develop students' independent learning ability and cooperation awareness. This stage focuses on allowing students to explore independently and proactively build knowledge structures. The student's learning process is composed of a series of learning activities. The most effective way to learn is to explore students independently. In the teaching, let the students practice themselves, accumulate perceptual knowledge, and realize the rational understanding through the brain's processing and thinking; through the practice exploration and cooperation and exchange, the various conclusions composed by the students themselves are the focus of this lesson, orderly Mastering the "10 division and integration" is the difficulty of this lesson. How to let students master this part of the knowledge is the key to this lesson. Therefore, the consolidation stage integrates knowledge and fun, using ten children's songs, which two flowers are combined, 10, password, train, find Lively game forms such as friends allow students to participate, so that students can consolidate their knowledge in a relaxed and lively atmosphere. After summing up, I went back to the game of guessing the ball, and changed it to the teacher. The student guessed, let the students experience the success of learning and enhance the self-confidence of learning.
In order to make students do not memorize the number of points and combinations, so in the teaching, let students do their own hands, brains, try to experience, can enable students to develop the flexibility of thinking in vivid and lively learning. Therefore, we must deal with the teaching materials flexibly when preparing lessons, carefully design each link, and the results will be more exciting.

10 division and cooperation teaching reflection model three:

First of all, the content of the 10 points and the combination is the basis of the learning addition and subtraction method in the future. It is used in the teaching of the "catch ten method" to calculate the carry addition and the "breaking ten method" to calculate the abdication subtraction. Therefore, it is very important, other than the other points. I spent more time studying with the co-arrangement, so I separated it and used a lesson for specialized teaching. I have set three teaching objectives in this section: 1. Decomposition and composition of 10 through hands-on practice, independent exploration, and cooperation and exchange. 2, through the children's songs, passwords, customs exercises and other activities proficient in 10 points and combinations. 3. Experience the idea of ​​splitting and combining in the activity and improve the interest in learning mathematics.
Throughout the teaching process, I mainly designed six links. 1. Review: Train the oral calculations in the form of “opening the train” and review the points and combinations of the numbers within 9 to pave the way for the 10 points of cooperation and cooperation. 2. Game introduction: Through a magic game, students will be envious of the teacher's "Gao Ming" to discover the secrets, and stimulate children's interest in further study and exploration. 3. Team cooperation to jointly explore the division and integration of 10: In the previous teaching, the students have already had the basis of division and integration within 9 degrees. They have also initially learned how to divide them in order, that is, one by one. Points, it should be said that the knowledge base and operational foundation are ready. So in this part, I let the students let them use the tools in the group and write them by themselves. It not only allows students to brain, hands-on, and verbally, but also allows students to experience the division of labor and cooperation in the group. Make students learn to interact with others in the process of learning. 4, the division and integration of memory 10: In order to let students consolidate the knowledge they have learned in a relaxed and lively atmosphere, I have adopted a lively game form such as passwords and children's songs, so that students can master the 10 points and combinations skillfully. And there will be a rational thinking. 5. Consolidation exercises: Here I introduced a story of “Little Monkey Travel” and set up three levels of practice in the story. Explain the meaning of the question yourself and let the students do it independently. The students' interest in learning is very high. Unconsciously, the students are consciously and skillfully applied according to the understanding of the division and integration of 10. It not only adapts to the lively and active personality characteristics of the first-grade children, but also cultivates students' interest in learning mathematics. 6. Summary evaluation: Let the students speak their minds and talk about what they learned in this lesson. Let students develop a good habit of summarizing and summarizing themselves. Finally, let the students rate themselves, the score is 10 points, the place where the performance is good accounts for a few points, and the place where the performance is not good accounts for a few points, so that the students feel the score of 10 again and again while evaluating themselves.
In short, in order to make the students do not memorize the number and combination of the numbers, I have handled the teaching materials flexibly in the preparation of the lesson, carefully designed each link, in the teaching, let the students do their own hands, brains, and try Experience, so that students in the vivid and lively learning, cultivate the flexibility of thinking, but also received a better teaching effect.
Finally, the mathematics teachers gathered together. Teacher Zhou, Teacher Zhao and Teacher Guo discussed the lesson. At the same time, they raised the existing problems. For example, you can use the magic game to import more times. Or directly use it to carry out 10 points and combinations, more to play its role, etc., and some teachers proposed to finally return to the introduction, revealing the mystery of magic, so that this section is more complete; Zhao also proposed, a section Classes should be combined with statics and movements; we also discussed group teaching, how to better develop the learning habits of learning mathematics, and so on. All the teachers gave me valuable advice and gave suggestions for improvement. I have benefited a lot. I think I will slowly improve it in the future teaching.

10 division and cooperation teaching reflection model four:

One. More successful places:
1. Fully mobilize students' senses, create scenarios for students, and enable students to learn in discovery.
According to the characteristics of the textbooks and the psychological characteristics of the first-grade students, the sugar-sucking game was introduced as an introduction, and many small games were designed in the teaching process. These scenarios were fully applied to carry out teaching, stimulating the enthusiasm of students, and fully mobilizing the students. Unintentional attention, to learn in discovery, to consolidate new knowledge in the game.
2. In the practice of practice, develop the flexibility of students' thinking.
The teaching of the division and the combination of the numbers is very important for the students to further understand the size of the number, the relationship between the number and the number, the meaning of the penetration and subtraction method, and the calculation method within 10 degrees. In order to make students do not memorize the number and combination of the number, so in the teaching I let the students do their own hands, brains, try to experience, can enable students to develop the flexibility of thinking in vivid and lively learning.
3. Let students work, brain, and participate actively to develop migration skills.
Mathematical learning is not simply a matter of knowledge acceptance. Mathematical learning is an activity. Like swimming and riding a bicycle, this kind of activity is not subject to personal experience. It is impossible to learn by reading books, listening to explanations, and observing other people's presentations. Therefore, I attach great importance to students during the teaching process. Experience the generation of new knowledge.
In order to enable students to learn from the study, they must improve their abilities. Therefore, students are allowed to participate in the teaching and actively participate in the teaching. They have learned to use the 5, 6, 7, 8, and 9 points previously learned. The learning method of learning to learn the 10 points and combinations, cultivated their ability to migrate.
4. Use group collaborative learning to give every child a chance to succeed.
Happiness and happiness, confidence and courage come from success. It is the requirement of the new curriculum standards to make every student have the opportunity to succeed in learning. Of course, it is the responsibility of our teachers. Therefore, in the teaching activities, I use the group learning method to let each child participate and choose, so that students at the learning level can get exercise, get progress, and have a successful experience.
5. Highlight the "people-oriented" educational thinking and face all students.
Students are the masters of learning. The teaching has completely changed the passive learning style of students, and changed the "teachers say, students listen", rote memorization, mechanical training practices, so that students form a proactive learning attitude, dare to explore, and make the process of acquiring knowledge and skills. Becoming a process of learning, a process that students are willing to experience, a process of happiness.
two. Inadequacies:
The level of practice design is not enough, and the variety of questions is lacking.
The practice of the class only reflects two levels: one is the basic application, which refers to the same structure, the same type of questions, and the same level of imitative exercises, which are used to consolidate the new knowledge learned in the church, such as Think about doing the first and second questions; the second is the comprehensive application, which is the synthesis of the knowledge points learned in this class, and the combination of the knowledge learned in the class and the original related knowledge, such as "think about doing it" The third question and the fifth question of Exercise 4. However, the developmental application is not reflected, and the problem type is slightly single. This is the place that I should pay attention to in the teaching process in the future.
In short, in the bilateral activities of teacher-led and student-centered classroom teaching, teachers must find ways to touch the emotional field of students, and skillfully organize attractive teaching game scenarios between knowledge content and students' knowledge of knowledge, so that students can feel emotionally. Driven by the fun, and thus enter the active participation state, change the learning to active learning, change me to learn for me to learn, stimulate students' interest in learning, provide students with full hands-on opportunities, cultivate students' learning habits and learning ability. These successes are what I need to continue, and the design of the exercises is something I need to ponder in the future.

10 division and cooperation teaching reflection model five:

The division and integration of 10 is based on the composition of the number of students learning 2-9. The teaching focus is on self-exploration and mastery of the composition of 10. The difficulty of teaching is to enable students to explore simple rules in mutual communication and gradually improve their language skills. In order to highlight key points and break through the difficulties, I mainly use situational teaching and inquiring teaching methods in teaching methods. For example, the beginning of teaching creates a situation in the form of a game, let the students touch the beads, I guess the few beads left. After such a guess, the students’ desire for knowledge is immediately raised, and the order of teaching 10 is orderly. When I was sexual, I drew a picture on the bead map, painted it, demonstrated it, and guided it to everyone. Then let the students explore the remaining beads on their own, and then say that 10 can be divided into several and a few, and the consolidation in the back. In the game activities, the teaching strategy of introducing and releasing is also adopted.
In the study method, the cooperative learning method is adopted. The group is encouraged to openly explore the different points of the 10 sticks, and let the group members come to the stage to display one of the sub-groups of the group, so that the group leader can report the students in the group. Each kind of division makes each student have a sense of success, let the students change from the audience to the master, from negative acceptance to positive discovery, creating a sufficient environment for the students to understand and say in the words. In the midst of feelings, taste the joy of success.
Mathematics comes from life, and at the same time it is used in life. In order to better understand the division and integration of 10, the perceptual knowledge is raised to the stage of rational understanding, which can be related to real life. In this lesson, it is said that it accounts for a large proportion. For example, when you show a certain method of 10 on the stage, you should say it while you are on the side; when the team leader reports, you should talk about each method of division of the other students in the group; after completing the orderly division of 10, let the students Use the examples in life to talk about each of the 10 divisions, so that students can further understand the division and integration of 10 in the communication, better to reflect the mathematics from life, and apply to life.
In order to consolidate what I have learned, I finally designed a variety of exercises with rich forms and forms. For example: clapping games, driving trains, finding friends, etc. In the process of teacher-student interaction, interaction between students and students, students use their hands and brains together, and various senses participate in learning collaboratively, effectively consolidating 10 points and combinations in a pleasant situation. Knowledge, fun, activity and integration, so that students achieve a double sublimation in knowledge and emotion.
