How to learn math in the first year of junior high school, what to learn in math in the first year o

Mathematics is the best of all subjects.

My method is to listen carefully in class, even if you don't understand it, you have to listen carefully and memorize carefully. If you don't understand, you ask, ask the teacher to ask your classmates, when you don't understand some related questions, let them tell you by the way, I think they are willing to help you solve it, don't care about face, the problem is simple and don't understand.

Then you do more exercises, preview in advance, and review in time.

Honestly, I didn't believe in that either. It looks simple, but it works. I was like you when I was in my second year of high school.

At that time, the math score of 150 was usually about 8 points, but later I came to my senses, and two months later I took the 138 test. No exaggeration (addendum: I majored in physics and chemistry at that time.)

I didn't do well in mathematics in the college entrance examination, so I took the 132 test)。There is no need to lie to you As long as you take action seriously, I believe that there is always a reward for your efforts.

You are the same as me, I am also a freshman in junior high school, English is very good, Chinese is upper, mathematics is very poor, but the midterm exam unexpectedly got a full score, I think mathematics is a link closely linked to a link, class is not a little down, but also after class to do more questions, start with simple questions, and then improve the difficulty of doing questions, coupled with your unremitting efforts, I think you will succeed!

It's not a question of whether to add points or not, as long as you can go up in your studies, I will bless you if you don't give me extra points.

In fact, as long as you listen carefully in class, pay more attention to review and practice after class, it is important to lay a good foundation, you are only in the first year of junior high school, and there will be no problem.

It is also very important to preview before class, and ask your classmates or teachers for advice in time if you don't understand something.

Also pay attention to cultivating interest

Just listen carefully to the lectures.

Math in the first year of junior high school is pretty simple, isn't it?

When you go to high school and college, you don't know how "powerful" math is ==...

The main thing is to listen attentively in class, junior high school math is very simple, and I got the basic score in the book after mastering it, mine.

Well, I haven't seen anyone ask like this, in fact, everyone in each subject has different talents, if the talent is not enough, use mechanics, in fact, the methods are all fake.

Mathematics: positive and negative numbers, rational numbers, scientific notation and approximate numbers, integers, properties of unary equations and equations, preliminary geometric figures, understanding of straight lines, ray segments, angles, etc.

1. Positive and negative numbers. Positive and negative numbers are a way of expressing a numerical relationship, which reflects the difference in the quantity and direction of the things described.

2. Rational numbers. Rational numbers are a collective term for integers (positive integers, 0s, negative integers) and fractions, and are a collection of integers and fractions.

3. Scientific notation and approximate numbers. Scientific notation: A number greater than 10 is recorded in the form of ax10 n, where a is a number with only one digit of the integer digit, and n is a positive integer, this notation is called scientific notation.

Approximate number: The degree to which the approximate number is close to the exact number, which can be expressed in terms of precision.

4. Integer. Integer, which refers to a mononomial and polynomial, is a part of a rational form.

5. Properties of unary linear equations and equations. If there is only one unknown number (element), and the number of unknowns is 1 (degree), such an integral equation is called a one-dimensional equation.

6. Preliminary geometric figures. Some parts of a geometry are not all on the same plane, they are three-dimensional shapes.

7. Straight line ray segment. Straight line: There are no endpoints at either end, which can be extended infinitely to both ends, and the length cannot be measured.

Ray: A line that can be extended infinitely from one endpoint to the other, the length of which cannot be measured. Line Segments:

There are endpoints at both ends, which cannot be extended to both sides, and the length can be measured.

8. Recognition of angles. Characteristic signs of angles: one vertex, two edges (straight). The size of the angle: It is related to the size of the two sides of the fork, and has nothing to do with the length of the two sides.

Importance of Learning Math:

1. Mathematics is closely related to our lives. If we want to talk about the real effect of learning mathematics, it is not reflected in the exam-oriented education, but in the future one's own thinking.

2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel for cultivating logical thinking.

3. The application of mathematical knowledge in life is ubiquitous. From the calculation of the cost of firewood, rice, oil and salt in daily life, to astronomy and geography, quality control, agricultural economy, and aerospace industry, there is a shadow of the use of mathematics.

Agree with the point upstairs: "Mathematical knowledge is like a chain, interlocking, and if one link is broken, it will fall short." The first year of junior high school mathematics is the starting point and foundation of the whole junior high school mathematics, so the first year of junior high school mathematics learning should be solid, we must do more exercises, we must understand what we don't know, cultivate more logical thinking, dare to study, don't be afraid of not, just afraid of retreating, and develop good study habits.

There is also the pre-class preview: do the simple questions like the "Do It" in-class exercises to lay a good foundation.

Listen carefully in class and take good notes In fact, remembering in your head is the most important thing (I'm like that, a little lazy, hee-hee... Homework is done independently to test one's learning and consolidate one's learning.

Timely correction of the job.

And don't forget to review what you've learned.

There is also a small section to organize the main points, and a large chapter to summarize the content and main points.

This problem cannot be solved at once:

1. Prerequisites - mathematical knowledge is continuous and must have a foundation;

2. Don't be in a hurry - to learn mathematics well, you must first establish a steady and steady mind;

3. Thinking gymnastics - to be able to drill; will think; can use the brain;

4. Practice can be skillful - to be able to practice repeatedly;

5. Relatives must believe in their teachers - they must also have a good impression of the math teacher;

6. Initiative is the most important thing - it is best to be the representative of the mathematics class; The closest to a math teacher.

1) Listen carefully and try your best to understand what the teacher is talking about in class 2) Do some homework after class to consolidate the basic knowledge.

3) Review the mid-term and final semester as a whole, grasp the knowledge framework and the knowledge points in it, and know what knowledge to use to solve the problem when you see the topic. ok

Practice more and do more, open your mind, think thoroughly, and start from the details.

Theory combined with practice, combined with diagrams, more hands-on, diligent thinking.

Preview, review, and practice.

Read books, read books, read homework.

Preview, listen carefully, review.
