6.7 minus a few teaching reflections

6.7 minus a few teaching reflections Fan Wenyi:

The focus of this lesson is to further deepen students' understanding of the meaning of subtraction, and to see the correct subtraction formula and to express the meaning of the map.
The language ability of first-year students is not enough. In the teaching of this class, I pay attention to the training of students' ability to express pictures and express their ability. Let students talk more and practice more. First, observe carefully, understand the meaning of the pictures, and read the pictures. The text is then listed according to the question.
However, some students still use the addition formula to answer, mainly because of the conditions in the picture, because the number of boys, the number of girls, and the total number of people have told us that some students think that the combination of boys and girls Six people, listed as an addition formula, and ignored the problem. The key is to choose the conditions reasonably according to the question. The question is that there are several girls. The number of girls who have removed the boys from the total of 6 people is the number of girls. It should be calculated by subtraction.
Improve students' ability to read reading questions, and let students develop a good habit of reading questions. It can train students' orderly thinking and lay a good foundation for students to solve practical problems in the future. However, in the actual classroom, students are still found to have large differences. Some students are reluctant to say meaning and do not like expression.
In response to this situation, I think that the form of practice in the future teaching can be more diverse, giving students more time and guidance, so that students can fully express his understanding of the meaning of the map, so that more students can participate. Only in this way can students' thinking training be more effective and effective.

6.7 minus a few teaching reflections on Fan Wen 2:

Today, the teaching of "6, 7 minus a few", the focus of this lesson is to further deepen students' understanding of the meaning of subtraction, can see the correct subtraction formula and can express the meaning of the map.
The language ability of first-year students is not enough. In the teaching of this class, I pay attention to the training of students' ability to express pictures and express their ability. Let students talk more and practice more. First, observe carefully, understand the meaning of the pictures, and read the pictures. The text is then listed according to the question. For example: to guide students to say "a total of a few students, male students have several people, how many female students?" "How many radishes? How many and a few?" After the students listed the formula, come again What does it mean to say "6-4=2 6-2=4"? These are all to improve students' ability to read pictures and to develop good habits for reading problems.
However, some students still use the addition formula to answer, mainly because of the conditions in the picture, because the number of boys, the number of girls, and the total number of people have told us that some students think that the combination of boys and girls Six people, listed as an addition formula, and ignored the problem. The key is to choose the conditions reasonably according to the question. The question is that there are several girls. The number of girls who have removed the boys from the total of 6 people is the number of girls. It should be calculated by subtraction. In these days, the children in the 7th class are better than the children in the 8th class. Many children can express their meanings in a complete sentence and say it in three sentences. The children in the 8th class are still eager to think that the math class is It is necessary to do a good job of the problem, so that some children can do the problem with experience. Of course, the correct rate will not be high. In the question of asking questions, Jiang Yan of the 7th class can grasp the key points and accurately say "a total of several radishes". The 8th class of children raised their hands in anxiously and said "3+4=7 "This formula still does not understand what is called "problem." In addition, I think that the form in this class can be more diverse, giving students more time and guidance, so that students can fully express his understanding of the meaning of the picture, so that more students can participate. Only in this way can students' thinking training be more effective and effective.

6.7 minus a few teaching reflections on Fan Wensan:

The lesson of "6, 7 minus a few" is the first grade of the second grade mathematics of the compulsory education curriculum standard experiment textbook. It is based on the student learning more than a dozen minus 9. In the knowledge level and experience of the students, I have integrated the content of computational teaching through the main line of “cat fishing”, allowing students to actively participate in the problem-solving activities and develop students' individual thinking. .
In the past, when the teaching was reduced by a few dozens, it was generally for students to put a small stick or a round piece. Some students rely solely on small sticks to calculate the number. Over time, the error rate is high and the correct rate is low. In response to the psychological characteristics of the younger children who love to listen to stories, I use the familiar story of “cat fishing” to introduce new lessons. The students are very excited and stimulated their interest in learning. Create scenarios, hands-on operation, let students experience mathematics, in the process of operation, let students further consolidate the different calculation methods of “breaking ten reductions”, “continuous reduction” and “thinking to add and subtract”. “Which method do you think can make the cat brother learn fast?” How does the cat brother quickly calculate the answer? “In the process of vying to be a small teacher, students let students consciously compare and select algorithms in operational practice. One of the students comprehended the relationship between the various parts of the subtraction formula, and clarified the reasons. The flexibility of thinking. In teaching, it not only advocates the diversification of algorithms, but also guides students to choose the method that suits them in many algorithms, so that they are good at learning, willing to learn, willing to explore, and then encourage and praise through teachers. Evaluation, appreciation among students, further stimulates students' interest in learning.

6.7 minus a few teaching reflections on the essay four:

Today, the teaching of 6, 7 minus a few, although the students learned the number is 6, 7 addition, know the representation of the two figures, but also understand how to use the addition of the two parts together. This lesson textbook is a difficult task. Students should not only learn to calculate the calculation method of 6 minus 7 and 7 minus, but also understand the subtraction of the picture representation to solve the problem. Although more adequate preparations have been made, the teaching effect is still unsatisfactory. Looking back on this lesson, I have the following ideas:
1. The content of the lesson plan in this section is that the children plant trees. This material is related to the students' actual life and can carry out some environmental awareness education. In class, let students first observe the situation map and talk about what you know? Let the students look at the picture and ask what is required? How to formulate? Some students in the class were still using the addition method when answering. The reason for the analysis is mainly influenced by the conditions in the picture, because the number of boys, the number of girls and the number of people in total can be found by observing the situation map. Some people think that the total number of boys and girls is a total of six people, which is listed as an addition formula and ignores the problem. The key is to choose the conditions according to the reasonableness of the problem, so I will cover the parts required in the picture. It is easy for the students to understand. If there are 4 boys and how many girls are there, the total number of people must be reduced to the boys. The talent to get girls. The number of girls who removed the boys from a total of 6 people is the number of girls and should be calculated by subtraction. Ask the students to first say the meaning of the figure and then list the formula 6-4 = 2, then talk about the meaning of the expression, deepen understanding. In the same formula of 7 minus a few, it is also required that students first look at the graph to list the formula, and then talk about the meaning of the formula. Summary can be used to write two subtraction calculations. The teacher must present the subtraction of the picture to solve the problem, so that the students can repeatedly say that the figure and the formula are practical. Improve students' ability to read reading questions, and let students develop a good habit of reading questions. It can train students' orderly thinking and lay a good foundation for students to solve practical problems in the future. However, in the actual classroom, students are still found to have large differences. Some students are reluctant to say meaning and do not like expression. In response to this situation, I think that the form of practice in the future teaching can be more diverse, giving students more time and guidance, so that students can fully express his understanding of the meaning of the map, so that more students can participate. Only in this way can students' thinking training be more effective and effective.
2. In this lesson, students can master the calculations of purely 6 minus, 7 minus a few. Basically, you can say the division of 6 and 7 to calculate the subtraction of 6 minus 7 and 7 minus. Some students do not calculate. Skilled, the teacher should strengthen his review of the 6 and 7 divisions.
3. In general, the textbooks should focus on the familiar life scenes or fairy tale worlds, select the lively and interesting things that are beneficial to students to explore, and create vivid problem situations as learning materials to stimulate students' learning. The interest and motivation of mathematics mobilize the corresponding strategies and wit of students. However, in this lesson, the calculations were arranged, and the subtractive application questions indicated by the pictures were arranged. The teachings felt that the capacity was large and the time was not enough. The students were not solid enough to grasp the use of the subtractive questions indicated by the pictures. Still feel that it is better to be divided into 2 teachings.

6.7 minus a few teaching reflections Fan Wenwu:

I think the better aspects of the teaching of this lesson are: 1. Pay attention to the cultivation of children's language. The first-year children have just entered school, and teachers should pay attention to cultivating children in the classroom to express them completely. For example: 6-4=? Students are used to answering 2. This is the teacher should emphasize that 6-4 = 2 first read the formula, and then say the result. In this way, every class pays attention to training, and the students' ability to express is gradually improved. When I was teaching, I asked the students to look at the pictures and say the pictures. 2. Focus on cultivating students' thinking ability. Let students replenish the formulas that are not available according to the existing 6.7 reduction formulas, and develop their thinking skills step by step. Of course, this class also has some areas that I am not satisfied with. In practice No. 4, students do not understand some rules of subtraction. They need to guide them to discover and summarize them.
