1. When reviewing questions, guide students to find out the key points and understand the meaning of the questions through the complicated stem parts.
When examining questions, students should pay special attention to the key words in the stem. The so-called keywords are the mathematical knowledge, specific data and known conditions involved in the topic. When reading math problems, students can hold a pencil and make symbols while reading. For example, draw the data with horizontal lines and circle the main points of the questions raised. In this way, when doing the problem, there is a good prompt function. Finally, when using the eraser, there is also a retrospective effect, and loopholes may be found.
2. Learn from the known, learn from the unknown, and read the questions.
When reading questions, distinguish between known and unsolved problems. The interrelation and interaction between the subject conditions, as well as the extension and broadening. Consciously cultivate students' ability to discover, identify, acquire and integrate information from materials. Consciously strengthen the conversion between written language and symbolic language, number and form, and the examination training of reading and writing.
3. Pay attention to the hidden conditions in the topic
Some conditions of some questions are not explicitly given, but are implied in the text narration. If students can't separate hidden conditions from problems, their thinking will be blocked and problems will arise when solving problems. For example, if the quadratic coefficient of a quadratic equation is not 0 and the denominator of the fraction is not 0, it proves that the angles of the sides of a triangle are congruent.
4. In order to examine the questions accurately, it is also important to eliminate the interference factors in addition to finding the key points.
Among the many conditions given by the topic, some are useful and some are irrelevant, and these irrelevant conditions are often deliberately set by the proposer. If any point is often drawn in the moving point diagram, this point is not the answer, but the interference factor. When reading a question, you should have a pair of eyes to distinguish between true and false.
