Strictly implement the party's educational policy, love their posts and respect their work, correctly impart knowledge to students, give them appropriate ideological education, and train them to become successors and builders of modernization in the new period. Seriously cultivate their sense of numbers, improve their computing ability, cultivate their concept of space, and apply what they have learned to real life to solve problems in real life.

Second, the basic situation analysis:

There are xx students in this class, including xx boys and xx girls.

1, double basics Most students have a good grasp of the knowledge that this book should have, especially the calculation of scores. But in practical applications, such as application problems, some students find it difficult to understand and solve problems.

2. Learning ability Most students are more active in learning, can consciously review after class and preview before class, and speak more actively in class. However, some students are more dependent, have poor thinking and analytical skills, are easily distracted in class, and their academic performance is not ideal.

Most students have good study habits. They listen carefully in class and basically finish their homework on time. Only a few poor students are lazy in their studies, so it is easier to finish their homework.

Third, teaching material analysis:

1, teaching content.

This textbook includes the following contents: negative number, cylinder and cone, proportion, statistics, wide angle of mathematics, arrangement and review. Cylinder and cone, proportion, arrangement and review are the key teaching contents of this textbook.

2. Teaching objectives.

If you understand the meaning of negative numbers, you will use negative numbers to express some problems in daily life.

② Understand the meaning and basic nature of proportion, solution ratio, the meaning of direct proportion and inverse proportion, be able to judge whether two quantities are in direct proportion or inverse proportion, and use the knowledge of proportion to solve relatively simple practical problems; It can draw pictures on grid paper with coordinate system according to the given proportional data, and can estimate the value of one quantity according to the value of another.

(3) You can see the scale, and you can enlarge or reduce simple graphics in a certain proportion in the form of grid paper.

④ Knowing the characteristics of cylinders and cones, the surface areas and volumes of cylinders and cones can be calculated.

⑤ Can accurately extract statistical information from statistical charts, correctly interpret statistical results, and make correct judgments or simple predictions; Preliminary empirical data may be misleading.

⑥ Experience the process of finding, putting forward and solving problems in real life, understand the role of mathematics in daily life, and initially form the ability to comprehensively use mathematical knowledge to solve problems.

⑦ Explore the "Pigeon Hole Principle". After I have a preliminary understanding of the "Pigeon Hole Principle", I will use the "Pigeon Hole Principle" to solve simple practical problems and develop the ability of analysis and reasoning.

⑧ Through systematic arrangement and review, we can deepen our understanding and mastery of the mathematical knowledge learned in primary schools, form more reasonable and flexible computing ability, develop thinking ability and spatial concept, and improve our ability to solve problems by comprehensively applying the learned mathematical knowledge.

Pet-name ruby experience the fun of learning mathematics, improve the interest in learning mathematics, and establish confidence in learning mathematics well.

Attending to form a good habit of writing homework carefully and neatly.

3. Teaching focus.

① Understand negative numbers in familiar life situations, read and write positive and negative numbers correctly, and know that 0 is neither positive nor negative.

② Know cylinders and cones and master their basic characteristics. Know the bottom, sides and height of a cylinder. Know the bottom and height of the cone.

③ Explore and master the calculation methods of lateral area and surface area of cylinder, as well as the calculation formulas of volume of cylinder and cone, and use the formulas to calculate the volume to solve simple practical problems.

(4) understand the meaning and basic properties of proportion, and know how to solve the proportion. Understanding the meaning of positive proportion and inverse proportion can help us find examples of positive proportion and inverse proportion in our life, and we can use the knowledge of proportion to solve simple practical problems.

⑤ Knowing the image with positive proportional relationship, we can draw an image on grid paper with coordinate system according to the given data with positive proportional relationship, and then we can calculate or estimate the value of another quantity in the image according to one of them.

If you know the scale, you will find the scale of the plan and the distance or actual distance on the map according to the scale.

⑦ Be able to comprehensively use the learned statistical knowledge, accurately extract statistical information from statistical charts, and correctly interpret statistical results.

⑧ After going through the inquiry process of "pigeon hole principle" and having a preliminary understanding of "pigeon hole principle", we will use "pigeon hole principle" to solve simple practical problems.

Pet-name ruby systematically review the knowledge learned in primary school.

4. Teaching difficulties.

⑤ Being able to comprehensively use the learned statistical knowledge, accurately extract statistical information from statistical charts and correctly interpret statistical results.

⑥ Experience the inquiry process of "Pigeonhole Principle" and solve simple practical problems with "Pigeonhole Principle".

⑦ By systematically reviewing the mathematical knowledge learned in primary schools, we can master and apply the mathematical knowledge learned in primary schools skillfully.

5. Teaching AIDS and learning tools.

Triangular plate straightedge cylinder, cone and model square for drawing.

Fourth, teaching measures.

1. Make full use of modern educational resources such as distance education resources and network to improve the intuition and visualization of classroom teaching and lay the foundation for improving teaching quality.

2. Actively learn the theory and experience of the new curriculum reform, further cultivate students' learning ability of autonomy, cooperation and inquiry, let them study easily and happily, let students learn from learning and ask me to learn, thus improving students' learning autonomy and learning efficiency.

3. Teachers should start from themselves, be strict with themselves, prepare lessons carefully, give good lessons, correct homework, influence students with a positive and serious attitude, improve students' interest in mathematics, and make students happy to learn.

4. Pay special attention to unit testing and close unit teaching.

5. Strengthen the training of outstanding and underage students, encourage and praise students to compete in their studies, so that different students can get different development, give more care to underachievers, ask more questions in class, care more after class, and correct their homework face to face.
