Problem-solving skills of multiple-choice and fill-in-the-blank questions in mathematics-elimination option method
Because the answer to multiple-choice questions is one of the four options, there must be only one correct answer, so we can use the exclusion method to exclude the answer that is easy to judge as wrong from the four options, so the remaining one is naturally the correct answer.
Method of assigning special values
That is, according to the conditions in the topic, select special values that meet the conditions or make special graphics for calculation and reasoning. When solving problems with special value method, we should pay attention to selecting values that meet the conditions and are easy to calculate.
Direct solution method
Some multiple-choice questions are adapted from some fill-in-the-blank questions, true-false questions and solution questions, so we can often adopt direct methods, directly proceed from the conditions of the questions, draw conclusions directly through correct operation or reasoning, and then compare with the options to determine the options. Most of us will use this method when solving problems.
The instruction of solving problems in the application of mathematics in Grade One is 1. Graphic analysis is actually a simulation method with strong intuition and pertinence, which is widely used in mathematics teaching. Such as engineering problems, speed problems, deployment problems, etc. It is often analyzed by drawing, and students can understand the meaning of the problem through charts, so as to set unknowns and list equations to solve according to the content of the problem. (Example omitted)
2. Personal experience method, such as sailing against the current, sailing against the current. Many students have never been on a boat, so it is difficult for them to understand the speed of sailing with the current, against the current and against the current. In order to make students understand, I take cycling as an example (because most students ride bicycles). The students all have personal experience. Riding with the wind is easy, but riding against the wind is difficult. This is the effect of wind speed. At the same time, it is clear that sailing boat and bicycle are the same thing, and the different factors that affect it are current speed and wind speed. In this way, students can understand.
Summarize, focus on training easy-to-mistake questions and strengthen knowledge points.
This work is not only a teacher's business, but also requires students to finish it independently.
When students summarize the topics, classify the topics they have done, know what kinds of problems they can do, master what common problem-solving methods, and what kinds of problems they can't do, they can really master the tricks of this subject and truly "let it change, I won't move."
The above are the methods and skills to share with you in solving math problems in senior one.
