Reflection on the composition of 3

3 composition of teaching reflection Fan Wenyi:

1, today's study of the composition of 3, the difficulty is still doing exercises, the children will put a pendulum, will also dictate, know that there are two ways to divide. But when I get to the homework, I am guilty. The teacher transcribes on the blackboard. It seems that the transcript will be wrong. Some will only copy it. I don’t know how to do it.
Reflection: The children still don't really understand the relationship between the numbers, they will put it in the real thing, and will dictate. But the transition from physical to digital is still difficult. This process is still going through the practice of the blackboard, and gradually become familiar with the digital.
The division of 3 has been interchanged. In the classroom, I asked the children to find two rules of separation. "Who can find out the rules of these two styles?" The children didn't know how to find them at first, I Another demonstration operation, at this time consciously exchanged, one child said "changed."
"The positions of 1 and 2 are exchanged."
If I asked this question at the time: "Is there any change in the position of 1 and 2?" This is much more straightforward than asking "what is the law" in general. The “numbers of the children” have just been contacted. When the teacher asks questions, they must design from the perspective of most children. The same problem is replaced by a different kind of statement, and the child will understand quickly. Teaching and learning, while teaching, teachers are constantly improving and improving their classroom questioning skills.
2, painting: grass flowers. In response to the children's coloring rough, uneven, and impatient, special practice to paint a large area of ​​color blocks, infiltration of the occlusion method. Some children's grass paintings are too high, and the results are not planted. In the future, the content of the screen should be less. Today, many trees are planted, and many children are not ideal. But there are also good works.
3, music: appreciate "snails and yellow ostrich".

The composition of the teaching reflection model 2:

The main problem of this activity At the beginning of this event, I will distribute 3 cars to 1 child and 2 children. The child will return the car to me. Ask individual children to make things clear in order. In the second component of Study 3, I asked the children how to "three cars can be divided?" When some children answered this question: 3 cars are given to 1 child; 3 cars are 1 person. 1 car.
Analyze the cause
As a new teacher, I did not expect the children to make such an answer during the event. This is also the requirement that I made before the event is not clear enough. In the activity, children often confuse the total amount in the physical map. For example: 3 apples, said 3 big apples.
Solution strategy
1. Clear requirements.
The two talents are divided into two.
The result of each score is different and is a different method.
Giving a person is not a point, it is all given.
The distribution of 3 cars to 1 person and 1 car is divided into 3 parts.
2. Correct the mistakes made by young children in time. Apples are big and small, so you can only represent them if you speak Apple.

3 composition of teaching reflection model three:

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 feeling for mathematics learning, and learning to enjoy it. This is the so-called "no burden under the music." Below, I will talk about my own experiences in the composition of teaching 3 and 4.
First, create a familiar situation for students and solve math problems in practice.
Vivid life scenarios help students understand mathematics in real life, feel the close connection between mathematics and daily life, increase the affinity for mathematics, and experience the joy of using mathematics. Therefore, in teaching, I often design some situations to make students learn easily while playing. For example, when teaching the composition of 3 and 4, after the lecture, I asked four students to come to the stage, each of whom sent a number. The teacher said that the two who formed the 4 were good friends, and the students became good friends by holding the two hands together. It is also possible to form a group of two who are good friends, so that not only will students quickly master the composition of 3 and 4, but also can carry out ideological education, and the students will unite and love each other.
Second, use guess as the driving force to guide students to explore the mysteries of mathematics.
As everyone knows, every child loves to ask why, every child wants to explore some secrets. According to the child's psychology, I have repeatedly used the form of "estimate, guess, guess" to let students think in curiosity and think. It has been gradually improved. For example, when teaching, I first told the students that I have a few beads, and there are several left-handers. Let the students guess that there are several right-handers. This is repeated several times, and the students master the decomposition and composition of the numbers in "guess". As well as adding and subtracting, it has deepened the understanding of logarithm and paved the way for mathematics in the future.
Third, self-study and mutual learning, feel happy in cooperation and exchanges
“Hand-to-hand practice, independent inquiry and cooperation and exchange are important ways for students to learn mathematics.” Today, “students are the masters of mathematics learning, teachers are the organizers, guides and collaborators of mathematics learning.” Students in the classroom sing the “lead” The teacher is only a "supporting role", leaving time and space to the students to think, explore, communicate, pay attention to the emotions, attitudes, and thinking that students show in the process of learning. I have used the form of "guessing and guessing" many times to let students think in curiosity and gradually improve in thinking.
The student's thinking is flexible, and the key is how the teacher moves. In this lesson, I practiced through various activities to make students "live", teachers and students to work together, feeling the joy of mathematics and infinite charm.
Fourth, increase confidence in the competition and cultivate a sense of competition.
Children's ambition, self-respect, and self-esteem, 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. For example, in the teaching, I use the group as the unit, the students have good discipline and answer the questions well, etc., and the group can get the red flag. The group’s red flag has the most red safflower, and in the individual, who can do it better than It is fast, so as to cultivate students' sense of competition.

3 composition of teaching reflection model four:

The new "Outline" requires young children to "perceive the quantitative relationship of things from life and games", but also to the ability of young children to explore, operate, communicate, solve problems and cooperate. The composition of the number is the basis of addition and subtraction, and it is one of the contents of mathematics education for children, and it is the necessary knowledge that children often encounter in their lives. By creating a corresponding environment, materials are provided for young children to do their own work and brain. Guide young children to explore, experience understanding, find problems, solve problems, draw conclusions themselves, and express their knowledge in an exchange.
The focus of this activity is to let the children learn the composition of 2 and 3, know that there are two methods for dividing into two, and there are two methods for dividing into two. The difficulty of the activity is to recognize the number of points, and to pass the number and the combination. Feel the relationship between the whole and the part.
The activity is created by the situation creation, so that the child can divide the radish independently. The initial perception 2 can be divided into one and one, guiding the child to say "2 can be divided into 1 and 1", and then lead to the comma and let the child pass the self. The fingers are placed together to consolidate. On the basis of this, the distribution of 3 is derived, and the distribution of the physical book is also used to divide the child's self-experience 3 into two ways, and at the same time, the child can use the combination to calculate the division of 3. Young children are more active in the course of activities and can be put into the situation I created. Finally, the operation of “sort by feature” will help children consolidate their activities.
This activity changed the teaching mode of "teacher teaching, preschool learning" in the past mathematics activities, and created game scenarios such as "dividing food for small animals" and "storing books with good friends", so that children can play in middle school. Happy Middle School has fully stimulated children's interest in learning. Through the whole activity process, by letting the children try to explore on their own, they know that there are 1 division in 2 divisions, 2 divisions in 2 divisions, and know which two numbers are combined 2 and 3, and can use Clear language expresses the process of combining and combining. In the activity, the children showed a strong interest and experienced the joy of success, which fully reflected the new concept of “children in front, teachers in the back” and created a better environment for students to interact. The activity is better. However, there are also deficiencies in the activities. If the points are not considered, the points will be separated to learn to make the children have a certain degree of distortion, and should be improved in future activities.
