1, knowledge points: The knowledge points in this unit mainly include the understanding, measurement and calculation of graphics. Students need to master the basic characteristics of various graphics, the calculation method of area and perimeter, and unit conversion. In the mind map, these knowledge points can be taken as the theme, and each knowledge point can be deeply analyzed and explained.
2. Emphasis and difficulty: This unit focuses on the measurement and calculation of graphics, especially the calculation of area and perimeter. At the same time, some abstract concepts, such as unit conversion, also need students to master.
The difficulty lies in how to understand the basic characteristics of various graphics and how to correctly calculate the area and perimeter of graphics. In mind map, these important and difficult points can be marked with special symbols or colors to remind students to pay attention.
3. Application expansion: The learning content of this unit is closely related to daily life. Therefore, through mind mapping, students can be guided to apply what they have learned to real life. For example, by calculating the study area, students can try to calculate the area of their home rooms; By studying the calculation of perimeter, students can try to calculate the perimeter of the school playground.
In addition, we can add some expansive contents to the mind map, such as the calculation of combined graphics and the nature of symmetrical graphics, to help students further expand their horizons and thinking.
The benefits of learning mathematics:
1, cultivate logical thinking ability
Mathematics is a subject that needs logical reasoning, and learning mathematics can help us cultivate our logical thinking ability. This ability can help us to think more systematically and step by step when solving problems. In mathematics, we need to solve problems through reasoning and deduction, which makes our thinking more rigorous and meticulous.
This logical thinking ability not only plays an important role in the field of mathematics, but also can be applied to other fields, such as science, engineering and finance. By studying mathematics, we can learn how to analyze problems, draw conclusions and verify the correctness of the results.
2, improve the ability to solve problems
Mathematics provides solutions to many practical problems. Learning mathematics can help us understand how to solve various mathematical problems, such as calculation, proof and reasoning. At the same time, mathematics can also help us improve our ability to solve practical problems. In real life, we often encounter various problems that need to be solved, such as optimizing resource allocation and reducing costs.
By studying mathematics, we can learn how to turn these problems into mathematical models to solve, so as to get the optimal solution. This problem-solving ability can not only help us to complete our tasks better in our work, but also help us to manage our lives better.
Step 3 enhance creativity
Mathematics needs not only logical thinking, but also creative thinking. Learning mathematics can help us cultivate creative thinking and make us more innovative when solving problems. This ability can help us explore new solutions and put forward new ideas and ideas. Creativity is a very important ability in science, art, engineering and other fields. Mathematics can help us improve this ability.
By studying mathematics, we can learn how to look at problems from different angles and find new solutions. This enhancement of creativity can help us achieve our goals more successfully in our personal and professional lives.
