Basic knowledge points of mathematics in senior one.
Front-back (front-back positional relationship)
Knowledge points:
1, pay attention to the difference between describing the order of objects and describing the exact position of objects with words like before and after.
2. The deer is in front, who is behind? The answer is no, not only a squirrel, but also rabbits, turtles and snails are behind the deer.
3. Pay attention to let students describe the relative position of objects with words like before and after.
Up and down (positional relationship between up and down)
Knowledge points:
1. Understand the relativity of "up and down" in specific situations.
2, can use language to express the "up and down" position relationship of objects in actual situations.
Left and right (positional relationship between left and right)
Knowledge points:
1, you can describe the left-right position relationship of an object in language.
2. Can experience the relativity of left and right positions in the situation. Further understanding: if two people face the same direction, they see the left and right positions in the same order; If they face each other, they see the left and right positions in the opposite order.
Classroom (front and back, up and down, left and right comprehensive application)
Knowledge points:
Describe the position and order of objects by using the knowledge learned in the first three lessons.

Mathematics learning methods and skills
Review is a process of consolidating and improving what you have learned.
32 knowing what things should be like shows that you are smart; Know what things are, and you will have experience; Knowing how to make things better shows that you are very talented.
People often say that time is life, so we should control the life controlled by time and learn to manage our own time. We can be masters of time, life and ourselves.
Debris seems troublesome, but it is actually very effective, because it conforms to the laws of human memory, but it can save time.
Metaphor can turn boring knowledge into vivid and interesting knowledge. Teachers are always good at using metaphors to deepen students' understanding, and students should also be good at using metaphors to help them remember.
The foundation of deep understanding is deep memory, and it is most appropriate to teach knowledge through understanding and using memory. If there are similar formulas and theorems, they can be compared by list memory.
Don't regard learning as a dull logical thinking process. It is very helpful to use your imagination boldly in your study life to improve your academic performance.
If every class is regarded as a small battle, it is very necessary to fully preview before class, just like the police before the war.
In the face of setbacks, consciously adjust your psychological state and don't focus on painful experiences.
It is a long-term job to keep healthy and energetic. We should pay attention to cultivate our good habits, persist in exercise, and ensure abstinence and order in life.

Learning is a long-term and arduous mental work. If you study too hard and last too long, it will lead to study fatigue.
Study fatigue will not only affect your study efficiency, but more importantly, excessive study fatigue will also harm your health.
As the saying goes, no pains, no gains, let us grow. We must work hard. Learning is not an easy task. In order to get good results, we must make corresponding efforts.
The internal relationship between numbers and shapes, especially their essential attributes and scientific laws, is difficult to understand only by feeling, perception or representation. Only through thinking can we deeply understand and firmly grasp them.
A person shapes himself not only by what he was born with, but also by what he learned from his study.
Quick success and instant benefit can easily lead to failure, and learning should be gradual.
For different types of problems, we can adopt a variety of methods, and choose the correct method according to the actual situation in practice, which can save time and energy to complete the problem.
Teachers should always follow the train of thought, be good at mastering the key words in the teacher's explanation and establish their own knowledge structure.
Through the reflection and refinement of the analytical reasoning process in the process of solving problems in the last class, it is helpful to understand the content of the new curriculum.
Comparing and reviewing with charts can help us review our knowledge accurately.
For the knowledge with obvious progressive relationship, the knowledge circuit diagram can be drawn.
Doing problems is the most effective way to consolidate knowledge, and it is also an important link in the learning process.
Don't think that the teacher in the textbook said that even if you pass, you should know that these examples are often exams. Is the basic knowledge solid?
Thinking after questions is an effective way to improve knowledge level, deepen thinking depth and improve thinking tension.
Replace the completed result with the problem to see whether the known quantity given by the original problem can be reversed, or whether the known conditions drawn from the conclusion are consistent with the known conditions of the original problem.
"To do a good job, we must first strengthen his"-a good student is very good at consolidating his memory by using learning materials, thus improving his grades.
Textbooks have always been the focus of students' study. Therefore, we should not only master the concepts and formulas in the textbook, but also ignore some details in the textbook.
There are three types of questions that don't need to be done in reference books: questions that are completely mastered, questions that are beyond the examination outline, and questions that are too strange.
Teachers' questions are often related knowledge, difficulties or places where students are prone to make mistakes. Other students should pay attention to listening, listening and analyzing when they speak.
