Teachers should provide students with life materials, let life enter the classroom and make mathematics come alive. Only in this way can students be interested and teaching be effective. For example, when teaching "Understanding of Volume", students can intuitively understand the existence of volume in life and help them understand the abstract concept of volume through the life scene of "crow drinking water". By involving students in activities, students can feel the concept of volume and stimulate their interest in learning. In this way, students really understand and master mathematics knowledge in the process of independent inquiry. At the same time, the experience gained in this process is helpful for students' further study.
Second, using modern technology to improve the effectiveness of classroom teaching.
Compared with conventional teaching methods, modern teaching methods have their unique advantages. In the usual teaching, we should use multimedia technology reasonably according to the characteristics of teaching content and students' cognitive level and thinking level, so as to make proper use of multimedia, give full play to its advantages and specialties, and promote students' positive thinking. For example, "knowing the clock" in senior one should be said to be a difficult problem for senior one children. I make good use of multimedia to show the characteristics of hour hand, minute hand and second hand intuitively, so that students can experience how to know the time and how to distinguish hour hand, minute hand and second hand in animation, and students can master it well. Teachers can use modern educational technology flexibly, which not only effectively promotes students' positive thinking, but also solves teaching difficulties well, thus greatly improving teaching efficiency.
Third, give play to the leading role of teachers and improve the teaching effect.
Primary school students' learning mathematics is a process of acquiring mathematical knowledge under the guidance of teachers' inspiration. In this process, students must have their own positive construction activities. Because students are in the stage of seeking knowledge, it is not only necessary but also necessary for teachers to inspire and guide them. Therefore, under the guidance of the new educational thought, it is an important aspect of promoting students' development and improving teaching efficiency to do a good job of teachers' guidance on students' mathematics learning. Teachers should guide and help students learn to organize knowledge and promote the construction of students' knowledge. For example, in the problem of solving equations I teach, in order to make students clearly and properly understand the equation in the form of "ax+b=c", I pave the way for students step by step, actively guide and encourage students to explore solutions to problems from different sides and angles, dare to be unconventional, and put forward original opinions and novel solutions. After my guidance, the students all came up with the method of solving by using quantitative relationship and backward deduction. Either way, the teacher should guide the students to know not only why, but also why. Only in this way can the efficiency of classroom teaching be improved.
Fourth, effective cooperative learning to improve the effectiveness of classroom teaching
The new curriculum standard puts forward: "Effective mathematics learning activities do not simply rely on imitation and memory, but on hands-on practice, independent exploration and cooperative communication." The learning process of students is the process of interaction between students and the outside world, and cooperation is a kind of recognition and acceptance. Communication and cooperative learning are mainly realized through cooperative activities. Therefore, when teachers organize group communication and cooperative learning, they should "throw" the questions that need to be discussed to the study group, so that the group can discuss them cooperatively. Therefore, in teaching, as teachers, it is necessary for us to carry out group cooperative learning, strengthen group communication and cooperation, and promote the development of students at all levels in the collision of ideological sparks.
