Let me share the children in my two classes first:

This is the original summary cover

Based on the suggestions of my friends, I have made the following adjustments

These are the teaching content arrangement of the textbooks published by Four Times and Five Times respectively, and the core objectives of each chapter.

there were originally two chapters in the fifth class, namely, observing objects (3) and graphic movements (3). Due to special reasons, last semester, observing objects (2) and graphic movements (2) were supplemented, and by the way, observing objects (3) and graphic movements (3) were challenged together.

This semester, we have made breakthroughs in three aspects, namely, fun, challenges and breakthroughs. Reflection

At the beginning of the semester, teachers must try their best to stimulate and mobilize every child's interest as much as possible, so the opening chapter of this semester is particularly important. First of all, the content of this chapter should not be too difficult, but it should be novel and vivid, and it should also contain various possibilities of exploration.

Therefore, I chose the chapter "Statistics". First of all, because it is closely related to our lives, it is relatively easy for every child. Secondly, it's fun. Every link doesn't have a definite and unique answer like algebra and geometry. More importantly, there are statistics in grades four and five. There are several new children in grade five. In the past, the way of learning statistics was completely different from that of Zhenyuan Education. Therefore, an interesting decision was made to combine classes in grades four and five. The decision to co-organize classes has already excited the children of the two classes.

when we encounter any problem that needs to be decided, we should make the final decision according to the following procedures.

In the new semester, we have come to a brand-new place-Kaifeng. What do we want to do most? Travel? Gourmet? But where to travel? What kind of food to eat? First of all, as soon as this question is thrown, all the children are excited.

Then determine the investigation plan and several scenic spots, and then look up the information on the Internet to get a deeper understanding of these scenic spots.

collect and sort out data, make statistical tables or charts, and then analyze the data and make decisions.

In the comprehensive stage, children decide a problem to be solved by themselves, and carry out a series of surveys and statistics. Make a questionnaire, collect and sort out the data in every class of the whole school, analyze the data and make a decision.

Use the weekend time to make it into ppt and share it with you.

Reflection in this chapter:

(1) The results of the discussion have not been really implemented, and children have not really felt the role of statistics.

(2) The links of making tables, bar charts and broken-line charts are not accurate.

Similar to the interesting and interesting chapter of graphic movement, after accurately learning the movement of symmetry, translation and rotation, we made Mother's Day greeting cards by using the movement of graphics.

The children are full of harvest, and the Song Dynasty is also full of harvest. The biggest harvest is to go to junior high school to attend classes. In the fourth grade, when I was doing graphic exercises, I just caught up with the axisymmetric chapter in junior high school. The accurate mathematical language in Junjie's class is very worth learning. I don't think what I did well enough is that I didn't let children use the movement of graphics to create more works freely.

In addition to making children feel fun and interesting, it is also necessary to lead children to the challenge of thinking at this time. In the collision of thinking sparks, fall in love with challenge loves to explore, such as the continuous challenge of brain maps and the breakthrough of papers.

Children are exposed to decimals for the first time. This school year, they will learn more about the meaning, nature, addition and subtraction of decimals. In addition to the core goal to be achieved in the precise stage, we also challenged the production of brain maps to see if our brain maps are getting richer and richer, and the construction process of secondary branches is becoming clearer and clearer.

We have not only created brain maps in this chapter, but also made brain maps in every other chapter.

The most memorable thing is that we invited President Jiang Zi to discuss this chapter of brain map sharing class. The children were very excited and their thinking in class was active, which surprised the teachers in the class.

For me, I have a more in-depth study on how to take a brain map class. How to discuss the core content of this chapter with children? In the past, I always ignored the discussion of the core content. Now I look at the previous brain map carefully, and the core content really needs to be discussed. Determination of each node of secondary branch. How to find out what the children have learned in this chapter but still have doubts according to their usual performance and the presentation of this brain map, and then share the challenges of the three branches. The most important thing is to implement it in time. When a temporary understanding is reached, it is necessary to leave a little time for the children to implement it on the existing brain map. After a class, every child should have his own unique brain map.

The fourth-grade children have heard that President Jiang Zi has given a class to the fifth grade, and they are very much looking forward to President Jiang Zi giving them a brain map class, which is an excellent opportunity for the whole school teachers to learn. This sharing class, I learned something new, one of which is of course the simplicity and accuracy of President Jiang Zi's language. Another point is how to give different children different possibilities in the future development, so that capable children can explore unknown areas with curiosity.

The next step is the breakthrough of the thesis. For the fifth-grade children, they have been exposed to thesis writing twice last year, but for the fourth-grade children, they have never tried it. Then, the first attempt will be a hit, so that children can feel excited and fulfilled in the process of writing. In the early days, I thought a lot about how to help children find a sense of accomplishment. The most effective thing is this time. Before writing my thesis, I announced in a high-profile way that eight children in grade four will choose two papers to be published on my website, so that excellent teachers from all over the country will read their articles and may even reward them. In this way, eight children have completed this thesis challenge with great care. Finally, they voted to select two best papers to push. What's more, the elected WeChat official account turned out to be WeChat official account of our school. God, you are amazing, you know? Who can publish articles in the school's WeChat official account? Only those excellent teachers can. Many teachers don't have such an opportunity. You can! It's amazing! You guys are amazing.

At the same time, the fifth-grade children are learning the chapter of factors and multiples, and they can't bear it anymore. After writing several papers, I will select several good papers in advance, print them and send them to every child, so that they can read them like famous people's articles, and then evaluate the papers, which are particularly good, worth learning and where they can be improved.

finally, select two papers to push.

In this way, children's enthusiasm for writing papers continues to rise, almost once a week. These papers include a review and arrangement of the knowledge learned, and also an exploration of a point of interest in the future.

Interesting flea market, from the initial determination of goods, to the production of posters, and then to the reflection of the whole activity process. After the end, we have to challenge a small paper. Oh, my God, if you don't write, you will be shocked. "Principal", "pricing", "selling price" and "profit" are silly and unclear. So-and-so, you will lose everything.

Reflection:

(1) The capable children were not allowed to accept more challenges.

(2) In terms of papers, the enthusiasm for writing was particularly high at that time, but due to their own reasons, they did not insist on following up. After the children finished writing the papers, they only revised them separately, but they did not continue to publish them in the school official.

Besides, we have made great efforts in practice. In principle, I should spend some time writing a series of more valuable papers for children to do. However, due to my lack of ability and limited time, I can only find relatively good papers from a large number of papers for children to do. After correcting each test paper, give the children about 1.5 minutes to correct it, correct the wrong questions within their power, and finally screen out the difficult questions for group discussion. Finally, the group sent representatives to explain. In the early stage, I felt that the practice class was taught in a different way, and the effect was particularly good, and the children's interest was particularly great. In this process, one after another small lecturers emerged, and the deepest memory was the change of Bodong in this link. In order to run for the team leader, he tried to finish all the tasks of the day ahead of schedule every day.

At the same time of group discussion in grade five, grade four also began to explore the nature of triangles by using the movement of graphics. This chapter is recognized as the most interesting lesson for fourth-grade children. In the whole process, we explore the characteristics of triangle edges by hands, discuss the characteristics of triangle inner angle sum in groups, and share the results in groups. The whole process gives children a full sense of accomplishment. You can feel his excitement from Han's expression.

At the end of the triangle brain map sharing class, President Jiang Zi left a question for everyone at the end. Are the external angles and uniqueness of the triangle determined? If so, how much is it? In this way, another brainstorming was set off.

I accidentally captured this video. Afterwards, I watched this short video many times. They couldn't help applauding Han. The laughter and excited expression from inside was so real and touching. At the beginning, Wang Han's group encountered a bottleneck. When they still had no clue, they suddenly heard that other groups had challenged success. So please come to help me. At the moment of success, I still remember the expression of each child at that time, but I don't know how to describe it. Anyway, my heart is warm, gratified and moved. Ye's excitement went straight to people's hearts. When everyone applauded for Han, the expression of satisfaction on his face and the light in the eyes of the stars ... < P > Then, Han invented his own new method, which he didn't share enough with the whole class, and he had to pull the Chinese Zhang who had just entered the class.

But after a period of time, I think it is far from enough to do so in terms of horizontal expansion and vertical depth, so I have the following wrong question analysis, which is a decision that makes me most surprised and fulfilled this semester. Children will analyze each wrong question, how they thought at that time, how to correct it, and whether you can quickly extract the test sites of each question, and then create three different questions according to the test sites and answer them. The previous analysis is of course a difficult point for most children. Many children's analysis is that I was careless, I misread the question, or this question has no idea, etc. After sharing the good wrong analysis with you, every child has been greatly improved in this process several times. Among them, what makes children like and stick to it is to make questions according to the test center, because in many exams, there have been questions that they have edited. When I told them that this is the questions that those proposition experts have made over the years, they were full of various sense of accomplishment.

finally, we awarded certificates of honor to three children who performed exceptionally well.

Yizhi is extraordinary in the problem-setting process. He can always give you some questions with special discussion value. When Yimei and Dayong just joined the River family, Yizhi designed a different test paper for them.

This session is the most fulfilling challenge this semester, but it also makes me feel the most exhausted, because it takes too much time to correct children's reflections and questions, and I haven't found a particularly effective solution yet. I always thought that most fourth-grade children were not able to reflect, so I didn't substitute this into fourth grade. However, by chance, some children tried to do a test paper analysis, which was great as a whole, so they also carried out test paper analysis again and again in the fourth grade.

The above is my sharing and reflection on the two grades' courses this semester. Next, I want to show you my children. Many places have left you beautiful.

next, let me talk about how our final homework is arranged.

One question a day, children can share the Olympic math choices they challenge every day with the group, and other children are free to challenge.

our team leader has made his own team plan early

our team leader will give feedback to his friends in time

What should I do if there is any problem? Send it to the group, let's discuss it together, or connect directly with Teacher Song Song.
