Mathematics concept is the key content of mathematics teaching, and it is also one of the important basic knowledge that students must master, and it is the necessary condition for the formation and improvement of basic mathematics skills. In primary school mathematics teaching, we will encounter many concepts and laws. If students can master correct and complete mathematical concepts on the basis of understanding, it will help them to master basic knowledge such as various properties, laws and formulas.
Contribute to the formation and improvement of various abilities. However, some students memorize these concepts and laws by rote, which will inevitably lead to mechanical copying when answering questions, affect students' understanding and application of knowledge, and also affect the development of students' thinking ability and the improvement of their learning enthusiasm.
Therefore, in the process of mathematics teaching, the teaching of mathematical concepts is particularly important. Based on teaching practice, the author exchanges and introduces the basic methods of mathematics concept teaching in primary schools, so as to achieve the goal of * * * and improve teaching efficiency.
Many concepts in mathematics are intrinsically related to old knowledge, so teachers should guide students to make full use of old knowledge and learn new concepts from it. This not only summarizes the old knowledge, but also learns new concepts, which is conducive to intensive reading and more practice. For example, when teaching the concept of "the basic nature of ratio", first introduce the basic nature of division learned before.
Review the basic nature of consolidating scores. Let the students understand that "divisor and divisor expand or shrink the same number (except zero) at the same time, and the numerator and denominator of the fraction are multiplied or divided by the same number (except zero) at the same time, and the quotient (fractional value) obtained remains unchanged."
From these two properties, students can draw the following conclusion: "The basic property of the ratio is that the former and latter items of the ratio expand (or contract) at the same time by the same multiple (except zero), and the ratio remains unchanged." Thus, we can master new concepts while reviewing and consolidating the concepts we have learned, and use and master new knowledge flexibly in our study.
