The content of "number sequence" is taught on the basis that students have mastered counting, reading and writing within 100. 1. In teaching, I pay attention to cultivating students' ability to explore independently on the basis of existing knowledge and experience. When filling in hundreds of tables, because students have already had the basis of counting, reading and writing, I ask students to fill in independently, thus forming a vivid representation of the numerical order within 100, which will further deepen the memory of the numerical order and lay the foundation for understanding and exploring the arrangement law of hundreds of tables.

2. By observing the horizontal, vertical and oblique positions of hundreds of tables, students can have a deeper understanding of the numerical order within 100, understand the position of each number in the numerical table and its relationship with adjacent numbers, and have a clearer understanding of the numerical size within 100. At the same time, through the observation of this table, we can find some interesting arrangement rules, develop students' thinking, broaden students' thinking, cultivate students' observation ability and expression ability, and improve students' interest in learning mathematics. After a class, I feel that the students are more active and the effect is better, but the time is not well grasped. I spent too much time observing this link, and I still have two exercises to finish. We should pay attention to proper control in future teaching.

Reflections on the second volume of mathematics teaching in the first grade of the second primary school

The focus of the course "Understanding RMB" is to understand RMB, but the difficulty is the conversion between RMB yuan and angular units. After teaching, I feel inspired and gained in the following aspects: in the teaching process of this class, I started with the familiar life scenes and interesting things, provided them with simulated RMB, stimulated students' interest in learning and introduced new lessons. Through simulated shopping, we can understand the role of RMB, deepen our understanding of RMB of various denominations, further understand the conversion relationship between RMB units, cultivate students' awareness of using mathematics and stimulate their interest in participation.

According to the characteristics of this class, I designed many activities. For example, the classification of RMB, different payment methods and so on. When simulating shopping activities, students' life experience is used to stimulate their interest in learning, so that students can actively participate in the learning process in simple activities of paying and calculating money, perceive the value and function of RMB, and cultivate their shopping ability in real life.

In this class, I have achieved my predetermined goal: while knowing RMB and mastering the conversion between RMB yuan and angular units, I have educated students to love RMB and inspired their patriotic feelings.

In a word, mathematics comes from life and is applied to life. In junior high school mathematics teaching, I think we should consider the characteristics of students, use teaching materials reasonably, stimulate students' interest in learning, create a relaxed learning atmosphere, and let students learn to study independently and cooperatively.

Disadvantages:

In teaching design, in order to stimulate students' interest in learning, I printed various denominations of RMB and showed them to students in class. As a result, students' interest in learning was stimulated, but they were also confused. Rural children see very little. They asked, "Teacher, is this real money?" "Can you take us there?" This shows that I have not done enough in preparing students. Although it was solved in time later, I still pulled my thoughts back.

Teaching should be "student-oriented", such as getting familiar with RMB in group cooperation and classifying RMB to provide students with communication space and opportunities for cooperation. However, in teaching, we still pay more attention to our own teaching design, and can't adjust teaching ideas in time according to students' learning situation. For students who are not familiar with coin sharing, we should grasp the question raised by students, "Is 5 points 50 points?" Allowing students to discuss may affect the completion of teaching tasks, but it is not advisable to avoid students' questions or perfunctory me. The activity of classifying RMB is not well organized, and many students read books. Reflecting on classroom teaching, teachers must adjust teaching according to students' learning situation.

First of all, the teaching of dividing money is not ideal. First of all, students are not familiar with penny-splitting, because "penny-splitting" is rarely used in real life, and I haven't said enough about it. The second is that pennies are rarely used, so I want to take them lightly. In fact, this is a primary course to be familiar with RMB, and it is equally important to be familiar with cents. However, cents are rarely used, but it can not be ignored for students to establish the concepts of yuan, jiao and fen and understand the relationship between yuan, jiao and fen.

Reflections on mathematics teaching in the second volume of the first grade of the third grade primary school

In the carry addition of two digits, how to carry when the digits add up to ten is the key and difficult point in teaching. Although students have the basis of two-digit plus one-digit carry addition. But there are still some students who are not very clear. In order to further break through the difficulty of carry, I designed a link for students to calculate by themselves in teaching. Through the process of hands-on experience before explanation, students can find a good calculation method by themselves and further verify it, which is impressive. At this time, most students can pay attention to carry when practicing two-digit plus two-digit carry. Judging from my patrol below, the children's calculations are basically correct. Individual children didn't add 1 carry, so I asked them to talk about arithmetic. Don't forget to add 1 to emphasize small carry. After knowing arithmetic and mastering the calculation method, I practiced and trained. From the feedback, most children have mastered it, but some children have made mistakes carelessly. But what some children are wrong is not that they don't know arithmetic and calculation methods, but that they copy the wrong numbers and symbols. It can be seen how careless and sloppy they are.

The advantage of this class is to pay attention to the cultivation of children's behavior habits, especially to children's listening. For the second-grade children, there is a student who never listens carefully in class. This semester, it pays attention to cultivating children from this aspect, and then evaluates children in time. The children in the lower grades are particularly excited about the little red flowers presented by the teacher, and they are very interested in learning with the encouragement of the teacher. This class also has shortcomings, that is, when teaching a new class, the teacher is always worried that the children will not understand, so the teacher talks more and repeatedly says that the children are not given enough time to speak. We should pay attention to avoid such problems in the future, and try not to say as little as possible. Let the students talk as much as possible and give them more time to practice.
