Many students find junior high school mathematics difficult to learn, and their grades are always unsatisfactory, especially in the important time of grade three. Many students are anxious because of their poor math scores in grade three. The following Boao education experts tell you some methods of learning mathematics in grade three.

First, examples of challenging unique styles.

Our daily homework is often based on what we learned that day, which is not difficult to solve; However, if you look at the senior high school entrance examination and imitation examination in various districts and counties in recent years, you will find that the requirements for students' ideological experience have been greatly improved, because what knowledge have you learned during this period of time? Can I solve it? What is the secret?

For example, it is known that the discriminant of equation x2+mx+2m-n=0 is zero, and x= 1 is the root of the equation. Find the values of m and n ..

If you don't look at the two conditions, you can list the equations about m and n, but the operation is very troublesome. If you analyze the meaning of the question from the group, you will find x 1=x2= 1. 1+ 1=-m， 1× 1 = 2m-n； ∴m=-2,n=-5。

Second, the preparation of knowledge networks

We have learned a lot of knowledge points and done a lot of problems, but the impression in our minds is often vague and isolated. We must find out the combination and difference through comparison and arrangement, and weave the knowledge into a network, so that we can have a clear mind and use it freely when solving problems, and form experienced experience in solving problems.

For example, what kind of quadrilateral geometry can distinguish between quadrilateral, rectangle, diamond or square with parallel sides? How many clues can you think of? What are the properties of their sides, corners and diagonals? What about symmetry? Unprotected summary summary once.

Third, choose reference materials.

In order to increase your experience in solving problems, you need one or two books suitable for your own situation as a reference. Mastering the following requirements can help you choose: the selected title is typical, and you should not engage in sea tactics; Rich in internal essence, inspiring, and able to understand a little arithmetic thinking method when solving problems; The difficulty is suitable for my acceptance and experience, not too high; The topics are arranged in layers, from shallow to deep, step by step.

Fourth, make up for the mistakes in solving problems

Don't complain about your "negligence" in solving problems in general, but discuss the wrong topic at once, whether it is because of inattention or lack of funds; Still reviewing the question and misinterpreting the meaning of the question; Or remember the wrong concepts, formulas and theorems; Still impatient and brilliant, keeping pace with the heartbeat, leading to incorrect operation and so on.

As long as we find the source, we can prevent the same inaccuracy from being revealed for the second time; As long as all the topics you can do are right, you can get good performance.
