How to deal with junior high school mathematics partiality? first stage
If children's mathematics is found to be biased in the first semester of junior high school (generally speaking, they can't pass the exam or worse), as parents, we should know more about their children's mathematics in primary school, then we will have some bottom in our hearts at this time, and then guess what caused it. Then communicate with the children and ask the teacher about the class and his own views on mathematics.
At this time, it is mainly necessary to guide children, such as telling some good personal stories of teachers and telling stories of parents learning mathematics at school (in order to guide children's goodwill towards teachers and interest in mathematics).
Turn good practices into habits.
Good habits will benefit for life, bad habits will regret for life and suffer for life. For example, does "mistakes in examining questions" lie in being eager for success? The tactics of "one slow and one quick" can be adopted, that is, the examination of questions should be slow and clear, the steps should be in place, the action should be fast, the work should be gradual, the stability should be fast, and the success should be based on one time. Don't get into the bad habit of being afraid of not finishing, rushing to do it and looking forward to the inspection.
In addition, the general examination is regarded as an important way to accumulate examination experience, and the general examination is regarded as the mathematics examination for the senior high school entrance examination, and it is constantly debugged and gradually adapted from all aspects. Pay attention to the writing standard, you can't lose important steps, and losing steps means losing points.
Look at this example from another angle.
Many students read books and examples, but they often pass by when they read them, because they often think they know everything when they read them, but they don't understand them thoroughly. So when you look at the example, cover up the solution, do it yourself, and look at it when you have finished or can't do it. At this time, think about what you did differently from the solution, what you didn't expect, what you should pay attention to, which method is better, and whether there is another solution.
Three ways to answer multiple-choice questions in junior high school mathematics problem-solving skills
There are three ways to answer multiple-choice questions in junior high school mathematics. Exclusion method: according to the question type and related knowledge, exclude obviously incorrect options. Special value method: according to the conditions in the topic, select special values that meet the conditions or make special graphs for calculation and reasoning.
When solving problems with special value method, we should pay attention to the selected values to meet the conditions. Methods of speculation and measurement: direct observation or conclusion. This method is often used to explore the regularity in the senior high school entrance examination questions in recent years.
Carefully examine the questions and strive for "one success"
After you get the test paper, you must first browse and understand the topic. First, look at the amount of questions, whether there is a printing problem; The second is to have a general understanding of the difficulty of the whole paper. We should understand the meaning of the topic word by word, pay more attention to the similarities and differences of deja vu topics, and explore the implied conditions and their internal relations from multiple levels. Thoroughly understand the meaning of the problem, such as "two circles are tangent", including circumscribed and inscribed, both of which are indispensable.
