School is about to start, which is a very important stage from Grade One to Grade Two, and the difficulty of knowledge points in various disciplines begins to deepen. Students who have attended extracurricular tutoring classes in the summer vacation probably know the difficulty of second-grade mathematics, so they will "preview" the new content of second-grade mathematics at home before class these days. The first volume of Grade Two Mathematics is divided into five chapters, namely, Chapter 1: congruent triangles, Chapter 2: Axisymmetry, Chapter 3: Real Numbers, Chapter 4: Linear Functions, and Chapter 5: Multiplication, Division and Factorization of Algebraic Expressions. Judging from the chapters learned, the input of mathematical graphics has begun to increase. The knowledge points in the first chapter and the second chapter are closely related. The most important thing is to talk about congruent triangles and his axis symmetry. The knowledge points in congruent triangles are not difficult to learn. The most important thing is to understand the reasoning process of each conclusion and thoroughly understand the inference, so that the questions with medium or above difficulty can be dealt with. If you want to cope with difficult exercises, you need to practice more and improve the flexibility of application. Linear function pays special attention to the mathematical thinking method of combining numbers and shapes, which runs through high school mathematics and even higher mathematics in universities. The first function should be related to the equations and inequalities of senior one. Therefore, when studying this chapter, we should review the contents of Grade One in time, so as to learn this chapter of function better, especially those students who didn't learn it well in Grade One! Learn the method of combining numbers with shapes, and maybe you will fall in love with mathematics! Chapter III Real Numbers and Chapter V Algebraic Multiplication, Division and Factorization mainly examine students' computing ability. In addition to mastering calculation skills, it is also essential to be careful. Therefore, students who usually do arithmetic should pay attention, or they will suffer a big loss in the exam! The above is a general analysis of the knowledge points of junior two mathematics. The ultimate goal of learning mathematics is to find "number" and "shape" and turn any formula and theory into immanence. In the most popular words, there is a question first, and then a formula pops out of your mind; Instead of having a formula first, then giving a question. This is a very important point when learning mathematics. Attention, students! More related articles 20 13 ruicai mathematics summer and autumn course enrollment guide thank you!
