First, the basic situation analysis:

There are 26 students in this class, including boys 1 1 and girls 15. Judging from the usual study and final exam last semester, students have a good grasp of basic knowledge and good study habits, which are mainly manifested in their ability to concentrate on lectures in class and finish their homework in time after class. But there are also some shortcomings: for example, some students don't finish their homework on time, they don't like to check after finishing their homework, especially they don't calculate carefully; Of course, some students do not do their homework.

Second, the book teaching material analysis:

The revised edition of the sixth-grade mathematics textbook published by West Normal University includes the following contents: percentage, cylinder and cone, statistics of positive and negative proportions, and general introduction. Compared with the textbook of nine-year compulsory education published by People's Education Publishing House, the following adjustments have been made.

1. Move "percentage" to this book.

In the original nine-year compulsory education textbook, the eleventh volume arranged the content of "percentage" After this revision, due to the adjustment of the content, the class hours have also changed accordingly, so it is very appropriate to move Percent to Volume 12, no matter from the point of view of class hours or content cohesion.

2. Adjust the "Classification and Review" section.

The main change of this unit is to adjust the related exercises according to the contents of the previous textbook, such as adding the related contents and exercises of "number and folding", adapting the related exercises of fractional addition and subtraction, fractional and decimal mixed operation and so on.

3. Add "comprehensive application".

(1) Mathematical problems in book purchase with prizes.

(2) Design the "June 1st" celebration program.

Third, the teaching requirements of this textbook:

1, so that students can understand the meaning of percentage and calculate it skillfully, which can solve some simple practical problems about percentage.

2, understand the meaning of proportion, know the name of the proportion of each part. Can use the meaning of proportion to judge whether two proportions are proportional, and can group the proportions. Understand and master the basic nature of proportion. Make students understand the meaning of positive-negative ratio and correctly judge whether two quantities are in positive-negative ratio.

3. Make students know the cylinder, know the names of each part of the cylinder, and master the characteristics of the cylinder. Understand the meaning of lateral area and surface area of cylinder, master the calculation method, and correctly use the formula to calculate lateral area and surface area of cylinder. Make students understand the derivation process of cylinder volume formula, understand and master the calculation formula of cylinder volume, and correctly apply the formula to calculate cylinder volume. Make students know the cone, master its characteristics and learn to calculate the volume of the cone.

4. Make students understand the meaning and use of fan-shaped juice chart, read fan-shaped statistical chart, master its characteristics, and learn how to make fan-shaped statistical chart.

5. The system firmly grasps the meanings of natural numbers, integers, fractions, decimals and percentages, as well as their relations and differences. Can read and write numbers skillfully. Be able to rewrite numbers skillfully. Be able to compare numbers skillfully. Master the concepts of integer division, divisor and multiple, prime number and composite number, and know the relationship and difference between them. Master the meaning and law of the four operations and the relationship between the parts of the four operations. Proficient in integer, decimal and fractional operations.

6. Deepen the understanding of the meaning and function of letters representing numbers, and use letters to represent numbers and common quantitative relationships. Master the meaning of ratio and proportion. The basic nature of proportion. Solution ratio. Further understanding the meaning of positive proportion and inverse proportion can correctly judge the size of positive proportion and inverse proportion.

7. By reviewing and sorting out some common quantitative relations that have been learned, and using these quantitative relations to write simple application questions, the students' ability to analyze and answer application questions is further improved.

8. Grasp the laws of the forward speed between adjacent units such as length, area, volume, weight and time, and improve students' proficiency in using these measuring units. Master the characteristics of various plane figures (straight lines), as well as their connections and differences. Can find out the axis of symmetry of axisymmetric graphics, know the names, characteristics and their relationships of the learned three-dimensional graphics, and develop students' spatial concepts.
