At the same time, according to my own understanding and teaching experience, I write some empirical articles to make myself grow continuously.
Work plan of mathematics teaching in the next semester of grade four
First, the analysis of the current situation of students:
There are 4 1 students in Class One, Grade Four. Students are interested in mathematics, have strong acceptance and correct learning attitude. From the perspective of students' knowledge, most students have a good grasp of what they have learned and can apply what they have learned to practice. Most students have a good command of oral calculation, calculation and application problems, while a few students (Zhao, Fang Bo) can't use them, but the whole class has a strong learning atmosphere.
Judging from students' study habits, some students (Hu Zhengyi, Pei, Jiang Zhilong) have poor study habits, such as writing slowly, copying wrong numbers, counting irregularly, and not being able to do problems with a ruler. For these reasons, the result is not ideal.
In terms of class routine, you can listen attentively and answer questions completely in class. However, some students (Zhao, Jiang Zhilong, Hu Zhengyi, Pei) are playing in class. When discussing problems in groups, some students are lazy and have poor teamwork ability.
In view of the above problems, this semester, while correcting students' learning attitude, we should set practical goals for all, fully mobilize students' learning enthusiasm and initiative, strengthen discipline education and routine training, strengthen the cultivation of their various abilities to learn mathematics, cultivate their good study habits, improve their ability to solve problems, and help every child learn valuable mathematics.

4. Let students know two kinds of composite bar charts, ask and answer simple questions, find information and analyze simple data according to the charts.
The concrete measures to improve the teaching quality of intransitive verbs;
1. Change the teaching concept
Have new ideas, new ideas, new experiences. Change the original concept of teacher teaching and student learning, and implement interactive learning (teacher-student cooperation, student-student cooperation, student network cooperation, etc.). ), and explore independently, so that teachers can create a relaxed, harmonious, friendly, democratic and happy learning atmosphere.
Students explore and discuss independently, and teachers should be good staff, logistics and student waiters.
2. Pay attention to the close relationship between life and mathematics.
Pay attention to learning and understanding mathematics from students' life experience and existing knowledge. In teaching, students' physical and mental development characteristics should be considered, and interesting exercises should be designed in combination with students' life experience and existing knowledge, so that they can have more opportunities to learn and understand mathematics from life. Attach importance to the extracurricular extension of mathematical knowledge and strengthen the practicality and openness of mathematical knowledge.
3. Pay attention to the openness of teaching and cultivate students' innovative consciousness and ability. Students are the main body of learning activities. In mathematics teaching, teachers should design some open questions according to students' age characteristics and cognitive level, so as to provide students with opportunities for independent exploration.
4. Facing all, comprehensively improve students' comprehensive quality.
Strengthen basic training, in terms of calculation, the focus is on strengthening oral arithmetic training. Attention should be paid to the practice of calculating application problems in one step. The implementation of hierarchical teaching and flexible teaching, according to students' different characteristics and different acceptance ability, adopt different methods, arrange different homework, pay attention to teaching students in accordance with their aptitude, and strive to "guarantee the bottom, not the top". Pay attention to students' classroom objectives and unit quality, strictly control homework, strengthen information exchange and timely feedback, and enhance the pertinence of teaching.
5. Teaching with practical problems
Einstein said: "Asking a question is often more important than solving a problem, because solving a problem may only be a skill problem in teaching or experiment, but asking a question requires creativity and imagination." I plan to focus on cultivating students' ability to question and ask difficult questions in teaching.
6. Homework design should be accurate, concise, standardized and convenient for teaching.
The improvement of students' academic performance depends on high-quality exercises, and attention must be paid to the design of classroom assignments and the performance of students' exercises. Homework in and out of class should be carefully designed, aiming at cultivating students' ability, embodying the spirit of curriculum reform, closely combining with life practice, paying attention to developing students' thinking and cultivating students' imagination and innovation ability.
7. Trinity, schools, families and society form a joint force of education.
The influence of family, society and school on students' education has its own characteristics and advantages. Only when the three are coordinated and learn from each other's strengths can we achieve good educational benefits. Teachers should take the initiative to get in touch with parents, communicate with parents about students' performance in school, cooperate with each other and learn from each other's strengths. At the same time, they should explain the education methods to some parents in time and properly, and educate students together.
Work plan of mathematics teaching in the next semester of grade four 4
I. Guiding ideology
Attach importance to providing students with familiar specific situations according to their existing experience and life experience, and help them understand mathematics knowledge. Increase the content of combining with reality to help students understand mathematics in real life and feel the close connection between mathematics and daily life. Pay attention to the choice of learning materials and activities that are rich in children's interest, stimulate students' interest in learning, and get a pleasant mathematics learning experience.

Most students are willing to take part in learning activities. Especially hands-on operation, they are more interested in the learning content that needs cooperation to complete. For the students in this class, I think we should pay more attention to maintaining the basically formed interest and gradually guide them to the fun of thinking and the fun of successful experience. Cultivating students' innovative consciousness and improving their innovative ability should be the most important issue this semester.
2. Analysis of the basic situation of students with learning difficulties.
Individual students are not interested in learning because of their poor foundation, wide knowledge gap, poor self-discipline, weak learning ability, poor acceptance ability and unclear learning purpose. Among them, some parents don't care, guide and supervise their children's learning enough; Some parents spoil their children too much and indulge them too much; Some bad study habits have affected his academic performance. The above reasons form a vicious circle, which makes them lose confidence and leads to the formation of underachievers. There are also several students who are mentally retarded and have poor acceptance. Therefore, continuing to strengthen the transformation of students with learning difficulties will also be the focus of my work this semester.
