Reflection on the Addition and Subtraction of 10

Reflection on the addition and subtraction teaching of 10 : Fan Wenyi:

The improvement of students' computing power, the oral calculation is the foundation, and the lower grade oral calculation is the basis of the foundation. The addition and subtraction method within 10 is the basis of carry addition and abdication subtraction, so the addition and subtraction method within 10 must make the students very skilled.
The teaching of the addition and subtraction and the composition of the number is taught so that the students can truly understand the arithmetic of addition and subtraction. Taking the composition and decomposition of 10 as an example, for example, 10 can be divided into 2 and 8, 2 and 8 to constitute 10. The meaning of addition is to combine the two parts and find out how much. The composition of 2 and 8 is to combine 2 and 8, that is, 2+8=10. Subtraction is to remove a part from the total, and to find another part, 10 can be divided into 2 and 8, so to remove 2 from the total 10 to leave another part 8 and remove 8 to leave another part 2. That is, 10-2=8, 10-8=2.
More important is the oral calculation plus subtraction training. On the basis of students' understanding of arithmetic, they carry out various forms of oral calculation exercises. For example, the composition of the number is written as a card for practice. When the card is presented, the card can be viewed by the student to tell the composition and decomposition of the number, or the card can be said to have two addition formulas and two subtraction calculations.
In addition, making oral calculation cards for practice, this step-by-step process can not only take care of students with poor oral calculation ability, but also improve the oral calculation ability of all students.
In addition to using cards to make students visual, but also pay attention to students' listening calculations, listening to students put forward higher requirements, requiring students to have a high concentration of attention, which not only improves the students' listening ability, but also improves the students' thinking ability. .
In short, listening, speaking, reading and writing are very important in oral training. In the composition of the number, the reading card, the reading calculation, the reading calculation, and the calculation, the students gradually increase the speed of the oral calculation. As long as they persist per day, they will achieve good results.

10 addition and subtraction teaching reflection model 2:

In the teaching of "Addition and Subtraction of 10", I cultivate students' self-learning, cooperative communication attitudes and habits. The whole class takes students as the main body and active learning activities under the guidance of teachers, so that students are rich in mathematics. The fun and usefulness of mathematics in learning activities reflects the basic requirements of the new curriculum standards. Let me talk about my specific experiences:
In teaching, I believe that students will boldly let the students explore and try.
At the beginning of this lesson, we use the power of guessing to guide students to explore the mysteries of mathematics. Every child loves to ask why, every child wants to explore some secrets. According to the child's psychology, I use the form of “estimate, guess, guess” to let students think in curiosity and gradually improve in thinking. .
Interest is the best teacher for students and the golden key to unlocking knowledge.
If primary school students have a strong interest in mathematics, they will have a strong desire for knowledge, showing a special emotion for mathematics learning, and learning to be happy, so I used the "study mode of mathematics law teaching" to teach, using courseware as a courseware. The tools for students to learn, at this time, information technology as a tool for discussion and expression. I show each of the 10 additions and subtractions to students in creating a living situation, and break through the learning style of using the idea map in the textbook, so that students can solve math problems in practice. For example, when teaching the formula 10-1=9, a large tree appeared on the screen of the courseware, with 10 cute birds playing, and suddenly a bird flew away. At this time, after letting the students fully observe the picture, let them talk about what happened and ask a math question. The student who asked the question has the right to ask another student to answer his question. In this way, it helps students to understand the mathematics in real life, feel the close connection between mathematics and daily life, experience the fun of mathematics and experience the close connection between mathematics and life, explore ways to solve problems, and enhance the subject of students' learning. Sex.
Cultivate students' diverse learning and develop their thinking skills.
In the teaching content, I designed the "open question" link - the number is filled in, the title is: +=10 10-= The purpose of designing this part is to make certain levels of students get a certain improvement, which is conducive to the child's thinking divergence. Sexual development.
Increase confidence in the competition and cultivate a sense of competition.
Children's ambition, self-respect, and love show themselves, so we must always create opportunities for students to fully perform, let them be psychologically satisfied, and constantly encourage them to build confidence, enhance courage, win or lose, and lose. Before the end of the course, I designed the teaching section of "Little Little Calculator". In the courseware, I presented the oral calculation card for this lesson, and organized the students to compete in small groups. This is a review of the content of this lesson, while at the same time enhancing their team spirit, the children are eager to try.
At this point, I feel that teaching resources are everywhere, and as long as they are used in a timely and appropriate manner, they can achieve unexpected results. Teachers should not only "teach high school" but also "learning in middle school." Only by fully and reasonably exerting the role of information technology can teachers be able to learn and learn, and let students continue to have successful experiences in the learning process, build self-confidence, and learn to learn.

10 Addition and Subtraction Teaching Reflections on Fan Wensan:

If primary school students have a strong interest in mathematics, they will have a strong desire for knowledge, showing a special emotion for mathematics learning, and learning to enjoy it. This is the so-called "no burden under the music." Especially the first-grade children are lively and active, and like to play games, so in the teaching I counted some game activities: looking for friends, singing, answering and so on. Through the game activities, the students' enthusiasm for learning is mobilized, the learning atmosphere is active, and the learning of knowledge is carried out in a relaxed and enjoyable activity.
I am teaching at three levels. First, I review the review: using the addition and subtraction method of learning to find a friend's game, using the oral calculations, all the members participate, reflecting the whole face, and greatly mobilizing the enthusiasm of the students; The second level is to teach new knowledge: this part of the teaching is divided into three parts. First, look at the picture and say the meaning of the figure, then say four formulas, and initially calculate the calculation method of the addition and subtraction method of 10, then look at the calculation formula and directly calculate the result, let the students say One said how you think about it. After affirming the various methods spoken by the students, it is pointed out that the method of composition of counts is fast and good; finally, the calculation method is consolidated through the oral calculation. The third level is to use various forms to examine the learning effects of students. First, find friends to add 10, then do the subtraction of exercise 10 in the book, and finally grab the game of cards to cultivate a sense of competition. Children's ambition, self-respect, and love show themselves, so we must always create opportunities for students to fully perform, let them be psychologically satisfied, and constantly encourage them to build confidence, enhance courage, win or lose, and lose.
In the future, improvement measures:
1. Strengthen the preparation of lessons. Seriously study the teaching materials of teaching materials, and consult with the teachers of the same group to correctly grasp the difficulties and difficulties of knowledge. Make the teaching process more reasonable.
2, the class pays close attention to the student's reaction, adjust the lesson plans at any time, so that it is more adaptable to the students' ability to accept, and is easy to understand.
3. Give more play to the subjectivity of students and give students more room for development.
We often say that interest is a magic weapon for students to learn. How to use this tool in class is a problem for our teachers. We must inspire students to learn happily according to their own characteristics, and to create a place to learn, it is necessary to adopt a variety of forms of teaching.

10 addition and subtraction teaching reflection model four:

The backbone classroom teaching and display activities of each semester, as I personally, are both a matter that needs to be taken seriously and a challenge of self-transcendence. Why do you say this? That is because the teaching work in the lower grades has been in existence for more than a decade. It can be said that every lesson has been deeply ingrained in my mind, but the more so, the more classes I have, the more times I do this. When you need to adapt to the new teaching philosophy, when you re-enter it, the pressure will be greater, and the more you need to think about the place yourself.
Looking back at this lesson, focusing on the teaching requirements of the school, taking stock of your own gains and losses, there are mainly the following feelings:
1. The teaching focus is accurate.
The focus of teaching is on the soul of a lesson. The focus of this lesson is that students develop their own rules and methods through self-exploration and mastery of the composition of 10 . I feel that it is better implemented in actual teaching. The generation of knowledge points in teaching is completed under the guidance and training of teachers. It not only plays the leading role of teachers, but also shows the process of students' independent inquiry. The role of both plays just right.
2. The training of students' thinking reflects the hierarchy.
The training of students' thinking has always been a new idea of ​​school teaching. This lesson begins with the process of student inquiry 10 and the subsequent practice design. The training points of thinking are promoted at different levels. Through hands-on operation and through orderly training in language, students will eventually develop the ability to master knowledge and use this ability to solve practical problems in life. The design of the exercise reflects the addition, the subtraction, and then the addition and subtraction, until the final solution to the problem, the core embodiment is the level and integrity of the training.
3. Accurately interpret the textbooks and use the cases in the textbooks reasonably.
The cases involved in the textbook are not free to show without purpose. In fact, the editor wants to tell us some information through some cases, it is very important to find out the information and use them reasonably for training. For example, there is a practice problem. There is only one training point in the textbook. When I want to class, I suddenly feel that the connection between the knowledge can be extended and extended slightly, which not only makes the content of the training more full, but also makes the knowledge The connection between the two sides is more compact, and the enthusiasm for student participation is also high, highlighting the timeliness of teaching.
4, practice design to fill without making a shelf.
As a child of the lower grades, the limited attention time in the classroom is only about 15-20 minutes. In these limited time, it is necessary to implement the teaching tasks and make the students interested. I think the design and implementation of the exercises. The form is very important. So I used a lot of interesting exercises to help me achieve the goal of teaching. All the exercises are vivid and interesting. In the end, it is all for the teaching goal. Without this, it can only be said that it is useless. waste time.
5. Time control of the teaching link.
The new teaching time for this class is about 15 minutes. The rest of the time is a lot of training. I think this is consistent with the idea of ​​the school's introductory and more practical teaching. It also makes the whole teaching process not lengthy and more A sense of rhythm.
6. Existing problems The training methods of some exercises should be more transparent and direct, so that when students see similar problems, the ideas and methods guided by the teacher are presented in their minds.
Feedback should be more pragmatic, and training for the wrong students is not enough.
Some teaching resources did not try their best to play their role, reflecting the new meaning of resources, but the use is not in place.
In short, every time the same class will come up with different feelings, constantly tempering and improving from it, will let yourself continue to improve, and will let others gain something, learn together, think together, and make progress together!

10 Addition and Subtraction Teaching Reflections on Fan Wenwu:

In the teaching of "Addition and Subtraction of 10", I am committed to changing the way students learn and the teaching methods of teachers, and to cultivate students' self-learning, cooperative communication attitudes and habits. The whole class takes students as the main body and under the guidance of teachers. The positive learning activities enable students to feel the fun and usefulness of mathematics in rich mathematics learning activities, reflecting the basic requirements of the new curriculum standards. Let me talk about my specific experiences:
In teaching, I believe that students will boldly let the students explore and try.
At the beginning of this lesson, we use the power of guessing to guide students to explore the mysteries of mathematics. Every child loves to ask why, every child wants to explore some secrets. According to the child's psychology, I use the form of “estimate, guess, guess” to let students think in curiosity and gradually improve in thinking. . I prepared a pack of rainbow candy before class, and found two good students to come to the front. Ask a student to give them the rainbow candy, guess how many pieces of rainbow candy, and guide the students to say what they think. . Then I asked the children to taste a piece of rainbow candy separately. Question: How many pieces of rainbow sugar are there now? Then introduce the topic.
