I have always stressed the importance of foundation. For the senior high school entrance examination, every point is very important. Even if you finally did the 12 question, the previous multiple-choice fill-in-the-blank questions were wrong two or three times, and everything was restored, especially the calculation questions of 17 and 18, which were completely given points and could not be deducted. Be sure to be quick and accurate!

If these points are deducted, if you want to get 140 points, you have to answer all the other questions correctly, and there is no room at all. Therefore, in these places, basic topics and topics involving algebra cannot be deducted.

You may ask, I'm serious about the basic questions, and it shouldn't be a big problem, but you said that all the questions involving algebra can't be wrong. This seems a bit difficult.

Let's take a look at what algebra in junior high school has learned.

One is the calculation of algebraic expressions, including addition, subtraction, multiplication and division. This also involves some absolute values and number axes;

Then there are various equations and inequalities, including calculating and applying formulas to solve problems; 、

Third, the content of functions, such as linear function, quadratic function, direct ratio, inverse ratio, etc., is difficult.

If you can get more than 120, I think algebra will be fine, such as algebraic calculation and equation solving. If you make a mistake, you will probably deduct the function part.

There are good ways to learn functions. In my opinion, the most effective way to learn functions well (including junior high school and senior high school) is to adopt the idea of combining numbers with shapes. When I talk about the number axis, I will spend a lot of time talking about addition and subtraction on the number axis (I'm afraid few teachers will focus on addition and subtraction on the number axis), and when I talk about absolute value, I will repeatedly emphasize the definition of absolute value rather than the calculation formula, because the definition of absolute value reflects the calculation formula.

My advice to you is that when doing function problems, you should always think about the problem-solving process with the idea of combining numbers with shapes, such as calculating the function value of an analytical formula, drawing the function curve as far as possible and marking the position of a certain point. After training many times like this, the functional problems are actually easy to control.

Second, the geometric finale must pass.

The difficulty of junior high school mathematics lies in geometry. Some auxiliary lines need to prove congruent or similar geometric problems many times. Not to mention students, many teachers may not be able to do it. It should be said that junior high school geometry questions test learners' thinking very much. To some extent, the finale of junior high school geometry problems is more difficult than senior high school mathematics problems. In fact, it seems normal for you to deduct points in this respect.

How to clear customs? There are still skills that you can break through in a short time.

Many geometric proof problems make students puzzled. In fact, they have rules to follow. For example, many teaching assistants classify the difficult topics in junior high school geometry: what rotation model, hand-in-hand model, fermat point model, invisible circle model, general horse drinking model, Hu Bugui model, Acheson circle model, folding transformation model, line segment and.
