You can try to reason about the theorems in the textbook yourself. This will not only improve your proof ability, but also deepen your understanding of the formula. There are many exercises. Basically, after each class, you have to do after-school exercises (excluding the teacher's homework). The improvement of math scores and the mastery of math methods are inseparable from students' good study habits. Therefore, good math study habits include: listening, reading, exploring and doing homework. Listening: We should grasp the main contradictions and problems in the class, try to think synchronously with the teacher's explanation when listening, and take notes when necessary. Every time after class, we should think deeply and summarize, so as to achieve one lesson at a time. Reading: Be careful when reading. To understand every concept, theorem and law, examples should be linked with similar reference books to learn together, learn from each other's strengths, increase knowledge and develop thinking. Inquiry: Learn to think, explore some new methods after solving problems, learn to think from different angles, and even change conditions or conclusions to find new problems. After a period of study, you should sort out your thoughts and form your own thinking rules. Homework: Review first. Think first, then write, do a class of questions, understand a large area, do your homework carefully, and standardize your writing. Only in this way can you learn math well. In short, in the process of learning mathematics, we should realize the importance of mathematics, give full play to our subjective initiative, pay attention to small details, develop good math learning habits, and then cultivate the ability to think, analyze and solve problems, and finally learn mathematics well.

Geography:

As a discipline, the study of law has many similarities with other disciplines. Such as: scientific learning attitude; Use your head, hands and mouth frequently; Ears, eyes, mouth, hands, heart, etc. At the same time, it also has its own unique learning methods. In fact, what we have been emphasizing is scientific learning methods and thinking methods.

First, the soul of geography learning-the use of maps

1. The classification maps of the Institute include sunshine map, statistical map, topographic profile map, geological map, geographical landscape map, geographical schematic map, geographical cartoon map, geographical data map, geographical structure map and geographical contour map.

2, learn to look at the picture ① Look at the theme ② Look at the legend ③ Pay attention to the details ④ Connect with reality.

3. Learn to change drawings ① Tu Tu transformation (section to plan) ② graphic transformation.

4. Learn to use painting ① to summarize geographical laws or characteristics. Memorize the geography of China through drawing ②: You can look at these maps, which are: the administrative map of China, the topographic map of China, the climate map of China (temperature and precipitation), the water system map of China, and the resource map of China (forest, minerals, hydropower, tourism resources, etc. ), China's crop distribution map, China's industrial distribution map, China's population, ethnic groups, cities and so on. Look at the pictures, remember them, or even draw them one by one, and you will have the basic knowledge of China's geography. Learning world geography:

1. Work hard on ten lines (five meridians and five latitudes).

2. Find out the natural landscape and human landscape in the area where the Tenth Line passes.

3. Draw an outline map within the latitude and longitude span of no more than ten degrees, tell the location, natural geographical features and human geographical features, and ask why. In this way, you will find that you begin to have a "picture" in your mind and a "truth" in your heart, and geography is no longer a monotonous text.

Second, the pillar of geography learning-understanding of textbooks

1, according to the outline, master the geographical principles and laws.

First, read the book thick: make reading notes on the book to supplement your understanding or find out your doubts.

Second, thin reading: organize and summarize knowledge to form a backbone and build your own "mind map."

2, the use of textbooks, learn to extrapolate, to find the general characteristics and laws of similar geographical things.

3. Use textbooks to summarize and master the rules of geography learning. For example:

Regional geography (continent or country): location, scope, population, topography, climate, rivers and lakes, resources, industry and agriculture, transportation and cities.

I believe that after hard work, students will love geography and learn it well.

In short, it is a process of accumulation. The more you know, the better you learn, so remember more and choose your own method. I wish you success in your study!
