1. Guiding ideology: Combining with our usual teaching, based on teaching materials and new curriculum standards, guided by district review suggestions, make full use of existing teaching materials, systematically review according to students' existing problems, actively guide students to consolidate what they have learned, help students to constantly sum up and give timely feedback, so that our review can reflect the effectiveness and improve students at different levels in the class. Second, review content: this semester we learned division with remainder, mixed operation, direction and route, large numbers in life, measurement, addition and subtraction of three digits, and even addition and subtraction. Identify figures (angles, rectangles, squares and parallelograms) and make statistics. Third, review goal: 1. Further understand and consolidate the knowledge learned this semester, and improve students' computing ability and problem-solving ability. 2. Experience the whole process of knowledge collation and review, and initially form the ability to summarize and collate knowledge; Deepen the understanding of the internal relationship between knowledge and form a knowledge network; Be able to comprehensively apply what you have learned to solve simple practical problems. 3. Through combing and reviewing the knowledge, gradually develop the habit of reviewing and reflecting, enhance the self-confidence in learning mathematics, and feel the fun of learning mathematics. Fourth, review the key points: key points: 1. Improve the accuracy and speed of calculation and develop good calculation habits. 2. Only by further clarifying the relationship between length units can we choose and use them correctly. Difficulties: through review, we can further understand the basic relationship between quantity and quantity, correctly answer the practical problems of two-step calculation, and improve the ability of analyzing and solving problems. Analysis of academic situation: students in this class 13. Students have good study habits, solid knowledge and many intermediate students. There are 3 top students, 7 middle students, and 3 students who are not particularly top students, and their learning ability is deviated, resulting in their grades hovering around 60, but there is room for improvement. Judging from the usual homework and exams, most students are highly motivated and have a solid knowledge. However, there are some problems, such as 1. Students can master the calculation method, but their calculation ability is poor, and they often mispronounce numbers and symbols, and do not develop the good habit of checking. 2. In solving problems, most students can master the methods of analyzing and solving problems, but their ability to draw inferences from others needs to be improved. 3. Students don't have a firm grasp of length units. Therefore, through the final review, students' knowledge, skills and logical thinking have been improved to some extent. Methods and measures: 1. According to the actual situation of students in this class, guide students to actively organize knowledge, review their learning process and gains, and gradually develop the habit of review and reflection. Lay a solid foundation of knowledge and skills, and at the same time pay attention to cultivating students' innovative consciousness and interest in learning mathematics. Systematize what students have learned this semester through general review. Grasping the key points and difficulties of knowledge and the internal relationship between knowledge, consolidating the knowledge learned, strengthening the knowledge that students are prone to make mistakes, the places that students have bad grasp, and the missing knowledge, so that students can improve on the original basis. 2. Problem-solving review can flexibly use teaching materials, closely connect with students' real life and create situations with materials nearby. Review should not be limited to the topic, but should focus on the analysis of the quantitative relationship in the topic, understand the relationship between conditions and problems, and choose appropriate methods to solve the problem. It is also necessary to cultivate students' ability to read pictures and solve problems. 3. Choose exercises according to students' learning situation and design various forms for review. For example, through games, practical operations and designing comprehensive review questions, students' interest in review can be improved, and students can be given the opportunity to comprehensively use what they have learned to solve problems and improve review efficiency. We should also reflect on the wrong questions (such as calculation and problem solving), find out the reasons for the mistakes and learn lessons. 4. For basic knowledge such as vertical, check, estimation, off-line calculation and other conventional topics, practice every day, prepare an exercise book, and practice 5 questions every day. 5. Pay attention to teaching students in accordance with their aptitude, strengthen training and make up the difference. Review should be for all students. Students who have the spare capacity to study should further improve through review. Pay special attention to students with learning difficulties in class, let them think more, talk more and do more, and finish their homework in time with the help of the little teacher. Face-to-face revision of the daily work of students with learning difficulties, and pass the customs in time. Do it every day, not in arrears. Be kind and patient with students with learning difficulties, gently persuade them, make them like mathematics, help them master the most basic knowledge and form the most basic skills. 6. It is necessary to consolidate students' basic knowledge and improve their thinking. Therefore, we should collect and classify the smart house questions in books, workbooks and test papers, so that students can do two things every day and explain them the next day. Top students are required to do these questions, while middle students can choose 1 or 2 to do them, and students with difficulties are encouraged to do them or not. By doing these questions, students are cultivated to love and be good at thinking, and their comprehensive ability and thinking ability are improved. In short, in the final general review stage, we should do: combine speaking with practice, and combine point, line and surface. First break through all knowledge points, then synthesize knowledge points, and finally solve problems in life, highlight key points and break through difficulties.
