1, get ready
First of all, be prepared for cognition. Let's be clear, it's not a big problem with the goal, it's a big problem with a limited time. Mathematics in the senior high school entrance examination is only 90 minutes, with 25 questions, with an average of less than 4 minutes.
Secondly, prepare the topic. A good reference book can provide a systematic and rich type of big questions. When you want to do it, you don't have to look around, you can find one at your fingertips.
Where can I find reference books? Search with Baidu, Zhihu, WeChat, etc. You will find a lot. Then enter the title of the book into Douban for comparison, and you can get a general understanding of the quality of this book. In addition, it is also a good choice to ask the teacher to help recommend one or two books.
2. Limited time training
Choose a big question and start timing from the exam.
There are two steps in doing the problem: the first step is to mark the key words and the parts that may be helpful to solve the problem. The second step is to deal with keywords, closely follow the marked keywords, and think about what knowledge points can be contacted and what operations can be performed.
First of all, marking keywords helps to grasp the topic comprehensively and avoid the situation that you start writing by feeling without reading the topic and lose points.
Secondly, the processing of key words is helpful to expand and promote ideas reasonably and avoid excessive divergence. For example, some students find it difficult after reviewing the topic, and they will stare at a word of the topic and think hard, drawing a lot, but the idea just can't come out.
Finally, these two steps are applicable to almost all junior high school math problems. If you consciously develop habits, the speed of solving problems will become faster and the scoring rate will become higher and more stable.
Step 3 sum up experience
Which keyword is missing? The exam is not careful enough, or the reading ability is not enough.
Which keyword has not been processed? Untreated keywords are often the breakthrough to solve problems and the key to keep scores.
Which keyword can't be processed? If you find such a keyword, don't let it go, it's a good opportunity to accumulate experience!
