Analysis of the sixth grade Olympic mathematics lesson plan;
First, the basic situation.
Total number of boys and girls 552827
Second, the learning situation
Most students are interested in mathematics (such as Hao, Zhou, Zhou, etc.). ), strong acceptance and correct learning attitude; There are still some students who are not conscious enough (such as Guo Chong and Guo Jialin) and can't take the initiative to study, which leads to difficulties in mathematics learning. Therefore, in the new semester, while correcting students' learning attitude, we should strengthen the cultivation of their various abilities to learn mathematics in order to improve their grades.
Before, I mastered the knowledge well:
1. Students firmly grasp the basic knowledge, concepts and definitions.
2. Students are better at oral calculation, written calculation and off-line calculation.
3. Students' ideas and steps to solve application problems are clear.
4. Students can answer questions about geometric drawing and graphics well.
5. The students' handwriting is neat and beautiful.
Disadvantages:
1, the student was careless and forgot to write the answer.
2, the use of knowledge is not flexible enough, which is manifested in the knowledge that has been mastered and cannot be used flexibly when doing problems.
Teaching material analysis:
This textbook includes the following contents: the application of percentage, cylinder and cone, proportion, positioning method, positive and negative proportion, problem-solving strategy, statistics and the general review of mathematics content learned in primary school for six years. These contents of this textbook are arranged according to all the teaching tasks of primary school mathematics on the basis of previous volumes. The key point is to let students know some common three-dimensional figures, master their calculation methods such as volume, and further develop the concept of space; Further form the concept of statistics, master the method of expressing the results of data sorting with fan-shaped statistical charts, and improve the ability of analysis, prediction and judgment based on statistical data; Understand the concepts of proportion, positive proportion and inverse proportion, deepen the understanding of some common quantitative relations, and use the knowledge of proportion to solve relatively easy application problems. Then systematically sort out and review the main contents of primary school mathematics, consolidate the mathematical knowledge learned, and enable students to comprehensively use the mathematical knowledge learned to solve relatively simple practical problems; Systematically arrange and review the new teaching content, further develop thinking ability, cultivate thinking quality and carry out ideological and moral education.
The cylinder, cone and proportion in this textbook are all important contents of primary school mathematics. First of all, understanding the characteristics of cylinders and cones and mastering some calculations of cylinders and cones can not only lay a good foundation for further learning the surface area and volume of other shapes and their calculations, but also further develop the concept of space, and can also enhance the strategies and methods to solve problems and gradually enhance students' awareness and ability to collect and process information. Finally, learning the knowledge of proportion well can not only enhance students' ability to deal with mathematical problems by mathematical methods, but also enable students to obtain the preliminary concept of functions and make preliminary preparations for further learning related knowledge. Therefore, it is the focus of teaching to let students understand the concepts of these contents and learn to apply these concepts, methods and calculations to solve some practical problems.
Teaching objectives:
1, let students solve practical problems with percentages. Understand the meaning of tax rate, interest rate and discount.
2. Make students know the characteristics of cylinders and cones in the process of observation, operation and other activities, correctly judge cylinders and cones, understand and master the calculation methods of cylinder surface area and cylinder and cone volume, and correctly calculate them.
3. Make students know the fan-shaped statistical chart, mode and average with examples.
4. Master the method of determining the position of objects by direction and distance.
5. In the process of solving practical problems, make students learn to seek the thinking of solving problems with transformation strategies, and determine reasonable problem-solving methods according to specific problems, so as to solve problems effectively.
6. Make students understand the meaning and basic nature of proportion and know how to solve it; Know the scale, know the scale and calculate the scale; Understand the meaning of direct ratio and inverse ratio, you can judge whether the two quantities are direct ratio or inverse ratio, understand the method of solving application problems with proportional relationship, and learn to solve easier application problems with proportional knowledge.
