Some suggestions on learning math well in junior two.
I. Reading Comprehension At present, there is a serious problem for junior middle school students to learn mathematics, that is, they are not good at reading mathematics textbooks and often memorize them. Paying attention to reading methods is very important to improve junior high school students' learning ability. To learn a new chapter, first read it roughly, that is, browse the branches of what you have learned in this chapter, then tick while reading, get a general understanding of the content of the textbook and its key points and difficulties, and mark the places you don't understand. Then read carefully, that is, according to the learning requirements of each chapter after the festival, read the content of the textbook carefully, understand the essence of mathematical concepts, formulas, laws and thinking methods and their causal relationship, grasp the key points and break through the difficulties. Read it again as a researcher, that is, discuss the context, structural relationship and arrangement intention of knowledge from the perspective of development, summarize the main points, finish reading the book, form a knowledge network and improve the cognitive structure. When students master these three reading methods and form habits, they can essentially change their learning methods and improve their learning efficiency.

Second, to improve the quality of lectures, we should cultivate the habit of listening and understanding lectures. Pay attention to the learning emphasis emphasized by the teacher in each class, the introduction and derivation methods and processes of theorems, formulas and rules, the tips and treatment methods of key parts of examples, the explanation of difficult problems, and the final summary of a class. In this way, grasping the important and difficult points and attending classes along the process of knowledge development can not only improve the efficiency of attending classes, but also change from "listening" to "listening".

3. Asking questions is an effective way to improve learning efficiency. In the process of learning, when encountering problems, take the time to ask teachers and classmates, and master the knowledge that you don't understand or learn in the shortest time. Set up your own error book and read it often to remind yourself not to make the same mistake twice. So as to improve the learning efficiency.
