First, return to textbooks and master basic knowledge.
Combined with the examination center, take the way of reconciliation, and pass the test one by one. Familiar with the common formulas and definitions of each unit, so that you can come with your mouth open. Be aware of the main problem-solving methods and problems in each chapter.
Second, practice the questions appropriately.
Do more exercises in order to master the learning skills and tricks from practice. Different problems have different methods and skills, especially the moving point in the function is a hot topic now. Do more, but don't do too difficult questions, focus on learning.
At the same time, don't care too much about the number of brush questions. Every time you do a problem, you can understand the formula theorem behind this problem and the idea of doing the same type of problem. Learning to draw inferences from others can not only improve the review efficiency, but also better grasp the knowledge points.
Third, grasp the key points and difficulties.
The focus of junior high school mathematics learning is function (including linear function, proportional function, inverse proportional function and quadratic function), with emphasis on meaning and nature; Triangle (including basic properties, similarity, congruence, rotation, translation, symmetry, etc. ); The properties, definitions and areas of quadrilateral (including parallelogram, trapezoid, prism, rectangle, square and polygon).
Special attention should be paid to understanding and mastering these important and difficult points in the review of special topics.
The significance of learning mathematics
First, enhance logical thinking and analytical ability.
Mathematics is a subject with strict logic. Learning mathematics can exercise everyone's logical thinking and analytical ability and improve their problem-solving ability. This ability is very important in daily life, study and work.
Second, cultivate abstract thinking and innovative thinking.
There are many abstract concepts and ways of thinking in mathematics. Learning mathematics can cultivate our abstract thinking and innovative thinking, and make us more capable of discovery and creation. This is especially important for innovative industries and scientific fields.
Third, improve mathematics literacy and mathematics application ability.
Mathematics is a subject widely used in various fields. Learning mathematics can improve everyone's mathematical literacy and mathematical application ability, so that everyone can better cope with practical problems and challenges. For example, mathematics is widely used in the fields of finance, engineering and medicine.
