The fourth grade mathematics teaching plan of PEP.
First, the class situation analysis
1, class introduction:
There are 36 registered students in Class 4 (1) and 29 registered students in Class 4 (2), most of whom are boys. Most of the students are from other places, and there are few local students.
2. Knowledge mastery:
Judging from the final quality inspection of last semester, students have not mastered the knowledge of double basics, nor have they mastered the knowledge of rectangles and squares, tons and kilometers.
In terms of calculation, students are very different, and most students can blurt out verbal calculations. However, due to some students' poor knowledge of multiplication and division, the speed of oral calculation and the correctness of calculation are directly affected, and the gap between students in this respect is very large. For some calculation problems, the calculation speed of some students needs to be improved, and various good habits of calculation need to be developed. The application problem is not well mastered. Only some students can carefully analyze the meaning of the question and express it correctly. They can't analyze the meaning of problems according to the quantitative relationship of application problems, and they don't have a good grasp of the structure of various application problems. Meanwhile, the ability to solve practical problems needs to be improved. This has brought some difficulties to the teaching this semester.
3, study habits, interests, methods and psychological characteristics:
Judging from the study habits, interests and methods, a few of these students have a strong interest in mathematics and can learn mathematics according to the correct learning methods. They can abide by the classroom rules in class, concentrate on their homework, finish their homework carefully, and ask questions boldly in time if they don't understand. More than half of the students usually have bad study habits and attitudes, and they can't concentrate on their studies in class. They are distracted in class, their thinking is distracted, their learning purpose is not clear enough, and they can't even maintain the most basic discipline. Some students can't concentrate on influencing the students around them in class. However, some students are unwilling to speak in class and are not active in speaking. Effective classroom discussion and improvement of learning effect are the direction to be worked hard this semester.
From the psychological characteristics, most students like to show themselves in front of others, like praise, and have a strong sense of competition in the class; Poor students are passive, indifferent and unenthusiastic in class, and it is difficult to finish their homework, but they also like motivation.
4. Other factors:
Most students come from rural areas. They love labor, are proactive and have a strong sense of collective honor. Most of the students come from poor families, and their parents' educational level is generally not high. Although they have the desire to make their children successful, their educational methods are improper and the cooperation between home and school is not enough. There is a misunderstanding about "reducing the burden and pushing the elements".
Second, teaching material analysis
This textbook includes the following contents: understanding of large numbers, multiplying three digits by two digits, dividing divisor by two digits, angle measurement, understanding of parallelogram and trapezoid, composite bar graph, wide-angle mathematics and mathematical practice activities. The understanding of large numbers, the division of three digits by two digits, the measurement of angles, and the understanding of parallelogram and trapezoid are the key teaching contents of this textbook.
In terms of numbers and calculations, this textbook arranges the understanding of large numbers. Three digits are multiplied by two digits, and the divisor is the division of two digits. In primary school, after the end of this semester, all the contents about the understanding and calculation of positive integers will be taught. On the one hand, the study of this knowledge enables students to learn to express and communicate with large numbers, master computing skills in a wide range, and further develop their sense of numbers; On the other hand, through the study of decimal counting method, all aspects of knowledge about the concept of numbers are systematically sorted out and integrated, laying the foundation for students to form a scientific and reasonable mathematical cognitive structure; And pave the way for further systematic study of decimals, fractions and the four operations of decimals and fractions. So this part of knowledge is still the basic knowledge and skills that primary school students should master and form.
In terms of space and graphics, this textbook arranges two units: angle measurement, parallelogram and trapezoid, which are the key teaching contents of this textbook. On the basis of existing knowledge and experience, through rich mathematical activities, students can further understand straight lines, line segments, rays, angles, perpendicular lines, parallel lines, parallelograms and trapezoid, and learn some simple drawing methods; At the same time, we can gain the experience of inquiry learning, understand the characteristics of various graphics and their relationships, and promote the further development of students' spatial concept.
In terms of statistical knowledge, this textbook arranges composite bar charts. The textbook introduces two different forms of composite bar charts, vertical and horizontal, so that students can use their existing knowledge to learn to understand these two charts, learn to analyze data, further understand the role of statistics in real life and form the concept of statistics.
On the one hand, the textbook combines multiplication and division to solve simple problems in life with the knowledge of multiplication and division; On the other hand, arrange the teaching content of "wide angle of mathematics" to guide students to experience the mathematical thinking method of operation and feel the charm of mathematics through observation, speculation, experiment and reasoning. At the same time, let students learn to solve some simple practical problems with optimized thinking methods, cultivate students' ability of observation, analysis and reasoning, and cultivate their interest in exploring mathematical problems and their awareness of discovering and appreciating mathematical beauty.
According to students' mathematical knowledge and life experience, this textbook arranges two comprehensive application questions of comprehensive applied mathematics ── "How big is1100 million" and "Did you send a greeting card?" Let students have a realistic background through group cooperation and inquiry activities.
Activities, apply what you have learned to solve problems, experience the fun of exploration and the practical application of mathematics, feel the fun of using mathematics, and cultivate students' mathematical consciousness and practical ability.
Third, the teaching content.
This textbook is divided into eight units: understanding large numbers; Angle measurement; Three digits multiplied by two digits; Parallelogram and trapezoid; Divider is the division of two digits; Statistics; Mathematical wide angle; Review regularly. The above unit covers four fields: number and algebra, space and graphics, statistics and probability (mathematical thinking method). The specific analysis is as follows:
1, the knowledge in the field of numbers and algebra includes the understanding of large numbers; Three digits multiplied by two digits; Divider divides two digits into three units. The above three contents are the summary and improvement stage of integer teaching in primary schools, so the above contents are important basic knowledge and skills in primary schools. It is one of the teaching focuses of this textbook.
2. Knowledge in the field of space and graphics includes angle measurement; Parallelogram and trapezoid. The above two contents are the beginning of primary school geometry knowledge system learning. (The geometry knowledge in the first learning period basically belongs to the intuitive understanding stage). Therefore, this part of content learning plays an important role in further learning and cultivating students' spatial concept. It is another teaching focus of this textbook.
3. Knowledge in the field of statistics and probability (mathematical thinking method) includes statistics; Mathematical wide angle two units. Statistics mainly studies composite bar charts (vertical and horizontal), learns to understand composite charts and analyze data; The wide angle of mathematics gives students a preliminary understanding of the operational thinking and game theory methods to solve practical problems in life.
4. The content in the field of mathematics mainly focuses on the two units of three-digit multiplication and division, and solves some simple problems in life (simple multiplication and division application problems; Sum and difference of products, quadrature and quotient application; The basic quantitative relationship of travel problems).
