I. Analysis of Students' Situation There are two classes of mathematics this semester, one with 28 students and the other with 28 students. Most students have a good foundation and a high awareness of learning. Among them, Class One scored among the best in the unified quality monitoring organized by the Municipal Education Bureau, while Class Two scored lower, but it was also among the best in the city. But there are still some students who have poor study habits and poor foundation! Slow learning, lack of learning consciousness and initiative, bad habits. Such as Ning Hao, Wang Peng and Ma Ping. Among them, Zhang Jiawang, Ma Ma and Luo have excellent academic performance, flexible thinking and often use different methods to solve problems. However, some students, such as students from Class One, Class One, Class One, have poor comprehension ability and slow speed in doing problems. Plus, they are spoiled at home and a little strict with them, so they make excuses not to go to school. Academic performance can only linger on the edge of passing the exam, and study habits have not yet formed.
Second, the teaching content This textbook arranges two parts in the content of "Numbers and Algebra": the understanding and operation of numbers, formulas and equations. The first part includes three-digit and two-digit multiplication, integer elementary arithmetic, multiples and factors; The second part arranges a unit-using letters to represent numbers. This textbook uses four units of "space and graphics" and is divided into three parts for teaching. Part I: liters and milliliters; The second part: the understanding of triangle, parallelogram and trapezoid; The third part: symmetry, translation and rotation of graphics. In statistics and probability, this textbook arranges the study of simple and compound statistical tables, from block diagram to bar diagram, from one cell to multiple cells, and gradually arranges to describe data with a single bar statistical diagram. On this basis, it teaches simple broken-line statistical diagrams. This textbook also arranges four practical activities, namely "Wonderful Cup Piano", "Let's go for a spring outing", "Appreciation and design of patterns" and "Understanding our living space".

4. Make students understand and master the sequence of three-step mixed operation in the process of solving practical problems, and know the brackets, so as to correctly calculate the three-step mixed operation problems. In the process of understanding and understanding mixed operation, we can further accumulate the experience of mathematics learning, solve related practical problems with three-step operation and develop mathematical thinking ability.
5. Make students know parallelogram and trapezoid in the process of connecting with life and hands-on operation, and know their basic characteristics, so as to correctly judge whether a plane figure is parallelogram or trapezoid; Knowing the base and height of parallelogram and trapezoid can correctly measure or draw the height of parallelogram and trapezoid.
6. Make students experience the process of collocation or arrangement of several things, initially discover the rules in simple collocation and arrangement, and use the rules to solve some simple practical problems.
7. Make students discover and understand multiplication and division in the process of solving practical problems, and learn to apply multiplication and division to make some calculations simple.
8. Make students learn to determine the symmetry axis of axisymmetric graphics by origami and other methods, and further understand the characteristics of axisymmetric graphics; Can draw the symmetry axis of some simple axisymmetric figures. To further understand the translation and rotation of graphics, we can translate simple graphics twice in horizontal and vertical directions and rotate simple graphics 90 degrees on grid paper.
9. Let students experience the activities of exploring the characteristics of numbers (non-zero natural numbers) and know multiples and factors; Can find all multiples of a number within 10 and all factors of a number within 100 from natural number 1 to100; Knowing the characteristics of multiples of 2, 5 and 3, we can determine whether a number is a multiple of 2, 5 or 3; Know odd and even numbers, prime numbers and composite numbers.
10. With the help of a calculator, students can explore and master some laws of product variation and quotient invariance, and can apply these laws to practical calculations to properly solve simple practical problems. 165438+ 12, so that students can know the simple broken-line statistical chart, understand the structure and characteristics of broken-line statistical chart, and represent data with simple broken-line statistical chart; Initially learn to choose histogram or line chart to express corresponding data intuitively according to practical problems, and can simply analyze statistical charts.
13, so that students can understand and learn to use letters to represent numbers, and use formulas containing letters to represent quantities, quantitative relations and calculation formulas; Initially learn to take values according to letters and find the values of simple formulas containing letters; The formula of "ax bx" will be simplified.
Fourth, teaching measures.
1. Create life scenes to improve students' ability to solve problems. Most of the problems in mathematics textbooks are simplified or mathematicized. In order to make students better understand the thinking method of mathematics and improve their ability to analyze and solve problems, teachers must be good at discovering and excavating some divergent and interesting problems in life.
2. Combine the actual life, organize teaching materials reasonably, and improve students' ability to look at practical problems with mathematical thoughts. Mathematics education is to enable students to acquire the basic mathematics knowledge and skills necessary as a citizen and lay a solid foundation for students' lifelong sustainable development. Small classes must be held, and fresh topics in life should be introduced into the big class of learning mathematics. Therefore, in teaching, teachers should contact the reality of life, absorb and introduce contemporary and local mathematical information materials closely related to modern life and science and technology to deal with teaching materials, sort out teaching materials and reorganize teaching materials.
3. Pay attention to practical activities and cultivate students' ability to find mathematical problems. In order to let students learn mathematics knowledge, get in touch with and gradually master mathematics ideas, and constantly enhance their mathematics consciousness, it is necessary to strengthen practical activities in the process of mathematics teaching, so that students can have more opportunities to get in touch with mathematical problems in life and production practice, and understand the connection and difference between real problems and mathematical problems.
4. Pay attention to the process, encourage participation in mathematics teaching, and oppose the disadvantages of "emphasizing results over process". Modern teaching requires us to cultivate students' ability while imparting knowledge, and the formation of ability must depend on the teaching process, especially on whether students actively participate in the whole process of solving problems. Teachers can't solve problems instead of students, and they shouldn't always replace the learning process of most students with the understanding of excellent students.
5. Admit differences, pay attention to teaching methods and face everything. Teaching can't ignore differences, across the board. Differences are objective facts and can only be gradually reduced. We should recognize the different levels of students and put forward different requirements according to the differences. In classroom teaching, we should face all students and try our best to arouse their learning enthusiasm. We should pay special attention to taking care of poor students, let them participate in the classroom learning process, and pay attention to tutoring poor students in classroom practice. Excellent students should also pay attention to their intelligence and design some "smart questions" and "more exercises" to make themselves develop better. Teachers should carefully study teaching materials, closely combine with students' reality when preparing lessons, reasonably choose teaching methods and design every teaching link.
6. Make good use of evaluation language, encourage students to develop actively and give full play to their incentive function. On the one hand, we should encourage excellent feedback in class, on the other hand, we should encourage students whose answers are not accurate enough. Clear orientation and give full play to the diagnostic function of evaluation. Teachers should establish a correct evaluation concept in the classroom, skillfully use and use the host's language, understand and respect students, and make the classroom full of vitality. The fourth is to stabilize the existing achievements and strive to enter the reward ranking in the quality monitoring of municipal and central primary schools.
