1. Review goal: This textbook is the last textbook of Grade Three. Through general review, students can gain more solid knowledge, improve their computing ability, develop their sense of numbers, spatial concepts and application awareness, solve simple practical problems with their own mathematical knowledge, gain successful learning experience, improve their interest in learning mathematics, establish confidence in learning mathematics well, and fully realize the teaching objectives of this textbook and the first learning period. 1. Consolidate what students have learned and further improve their basic knowledge and skills through general review. 2. Through induction, arrangement and practice, improve and develop students' computing ability, sense of number, spatial concept, statistical thinking and application consciousness. 3. Enable students to solve simple practical problems with what they have learned, gain successful learning experience and improve their interest in learning mathematics. Second, the analysis of the class students: Based on the analysis of the actual situation of the students in the third grade at the end of the term, the students' learning mentality is not stable, and there are many mistakes that are eager to achieve success, mainly reflected in the multiplication of algebra median and double digits. Students use the draft book improperly, and hasty calculation is prone to errors. Some students confuse multiplication with addition. This problem makes students easy to make mistakes when calculating the thousands of numbers involved in the average. In solving problems (application problems), some students often write them down in a hurry without reading and understanding the problems, which leads to mistakes, especially in flexible regional problems. It is worth noting that the phenomenon of polarization has gradually emerged this semester. Excellent students can learn new knowledge easily, use it freely and have good study habits. Secondary school students have solid knowledge and can study independently, but their thinking is not flexible enough and they lack problem consciousness. Underachievers are slow to accept knowledge, not good at thinking and solving problems independently, and their academic performance is unstable and steep. Therefore, we should pay attention to both ends when reviewing, not only to make up the difference, but also to cultivate Excellence. Third, review the key difficulties and key points (1). The review focuses on division, multiplication, statistical knowledge, area and solving simple practical problems. (2) Review difficulties: We can correctly analyze and solve simple practical problems by using the knowledge we have learned, and strengthen the cultivation of statistical concepts and spatial concepts. (3) Review focus: inspire and guide students to learn to analyze and think in independent thinking and cooperative communication. Improve the ability to solve problems. Fourth, review content: (1) Preliminary understanding of numbers 1, decimals and fractions, and addition and subtraction operations. 2. Multiplication of two digits and two or three digits; Division and mixed operation between one digit and two or three digits (2) Preliminary understanding of space and figure 1 and simple figure, and understanding of its basic characteristics. 2. Understanding the perimeter of graphics and calculating the perimeter of rectangles and squares. 3. To understand the meaning of area, you can use optional graphic units to estimate and measure the graphic area, understand the necessity of unifying the area units, know and understand the area units, and carry out simple area conversion; By exploring and mastering the area formulas of rectangles and squares, we can estimate the area of a given rectangle and square. (3) Statistics Through abundant examples, I can understand the meaning of averages and realize the necessity of learning averages. I can get the average of simple data, ask and answer simple questions according to the data in the statistical chart, and exchange my ideas with my peers. (4) Combining practical activities with real life cases, using the knowledge learned to analyze and solve problems, and forming certain problem-solving strategies. V. Review points: (1) Teachers: 1, according to the learning situation of this lesson, make a review plan, prepare and do a good job in each review lesson. 2. Use various means to stimulate students' interest in learning, improve the teaching effect, pay attention to the integration, coherence and systematicness of knowledge, and guide students to sort out what they have learned. 3. While mastering the basic knowledge, comprehensively cultivate students' mathematical literacy, cultivate students' ability to summarize and reflect, and improve students' learning ability. 4. The design of review homework is hierarchical, comprehensive, interesting and open, and it is necessary to correct it in time, find problems in time, fill in gaps and clean up knowledge every day. 5. Pay attention to the work of cultivating excellent students, pay attention to students' learning emotions and attitudes, and strengthen communication with parents. (2) Student: 1. Ask for active learning in attitude, pay attention to review, dare to ask questions, and ask if you don't understand. 2. Listen attentively in class, think positively about speaking, and learn to listen to others' speeches. 3. It is required to finish homework on time and seriously after class, and conduct self-reflection in time. (3) Measures to improve and make up the difference: 1. Pay attention to learning and understanding number and counting knowledge from students' existing knowledge and life experience. 2. Students should take the initiative to review. Lay a solid foundation of knowledge and skills. At the same time, we should attach importance to the cultivation of students' innovative spirit. 3, grasp the teaching requirements, not too high, so that students can improve on the original basis. Select exercises carefully, not engage in the sea of questions. 4. Improve the evaluation of students. If they make mistakes, they can be rewarded, prompting students to check and analyze their mistakes and make continuous improvement. 5. Make up lessons after class, and take the form of "one-on-one" to mobilize students to help them make progress together, and at the same time get the cooperation of parents to encourage and supervise their progress. 6. Actively coach poor students, always pay attention to these students, and ask more questions in class, give more guidance on homework, practice more explanations, praise more, encourage more, and provide more opportunities for performance. Give some thoughtful questions to satisfy the students who study better. Sixth, review the specific measures: comprehensively understand and analyze the basic situation of students in this grade mastering the contents of each part. Then according to the actual situation of each class, make a feasible review plan comprehensively. 1. Calculation part: Calculation by multiplication and division: First, review the calculation rules and precautions, and focus on learning the calculation strategies and methods between two digits and three digits. 2. Problem-solving part: Focus on guiding students to analyze the quantitative relationship in the stem, and compare the stem with similar structure, so that students can see the conditions of the stem. When the problem changes, how do the steps to solve it change accordingly? 3. Geometry of figures: guide students to summarize and sort out, and help students distinguish the differences and connections between these figures. 4. Pay attention to the transformation of students with learning difficulties. In class, we should pay more attention, communicate with parents, change their learning attitude to the maximum extent, and strive for progress for these students with the help of the pressure of final exams. 5. Pay attention to adjust the review plan in time according to the problems in the review process. Seven, review class arrangement 1, divisor is the division of one digit, two digits multiplied by two digits ... solve the problem.
