1Improve the efficiency of primary mathematics classroom I seeMathematics teaching in primary schools and improve the efficiency of the teaching of primary mathematics teachers in elementary school mathematics put forward higher requirements, namely, how to minimize the time and effort to obtain the best effect of classroom teaching, teachers should fully understand the characteristics of primary school students to learn mathematics characteristics of teaching this course, on this basis, the use of appropriate means to improve the efficiency of primary school mathematics teaching. efficiency is teaching teachers and students in the teaching unit of time to complete the task, that is, time commitment, energy, and “produced” relationship. exhausted less time and energy, so that students maximize the learning effectiveness of classroom teaching, is to reduce the academic burden on students and improve their quality lies. First, insight into teaching materials for teachers to 1, teacher materials and establish a new concept. Materials for teachers and teaching students the major 2media, reading materials to improve primary school mathematics teaching became the basis of efficiency. Interpretation of reading materials that effective teaching, and grasp the content of textbooks in order to guarantee the teaching Huodong efficient conduct. teachers must first Chitou the idea of the new curriculum, new curriculum advocates “Students First” idea, is to allow students in a democratic, harmonious, pleasant atmosphere in class and actively explore new knowledge and experience of learning fun, and “all learning valuable math; everyone can get the necessary mathematics; different people get different in the development of mathematics.” To do this, we must carefully study the new curriculum standards, change the traditional teaching concepts. concepts do not change, the equivalent of a new name. 2, teachers need to thoroughly understand the intention of teaching. Teaching is dead, people are living. New curriculum requires teachers to use teaching materials, rather than teaching materials. Teachers can not reproduce the materials that make the teaching task is completed, must be re-processed to re-create , so that teaching 3materials, “freshly baked”, to a greater extent with the knowledge in the training of teaching attitude, ability to process. try to make students active and practical experience of their lives together, to experience mathematics learning is valuable, and the establishment of conscious perception of time students, penetration to develop your time and punctuality habits and study habits. Second, to achieve the optimization of the teaching process 1, to achieve the teaching objectives optimization. Educational goals to determine the direction of the teaching activities to determine the teaching content, methods, choices, decisions of teaching efficiency. Tailored for each child a different teaching objectives is unrealistic utopian, but the goal is feasible to develop stratification. can be divided into lower objectives, targets upper and development goals. If diversity in the teaching method, the author asked a number of weak students master the basic algorithm only requires can be, better ability to require the students will use a variety of algorithms, capabilities and better students will use a variety of algorithms based on the Institute of merit or 4come up with a better way. This departure from the student to design the cognitive differences between of the teaching objectives, the ultimate “at the same level for all students to get proper development.” 2, to achieve the optimal teaching methods. To improve the efficiency of classroom teaching, teaching methods should pay attention to the optimization. A reasonable use of multimedia-aided teaching, combined with sound, animation, etc., can increase student interest in learning, stimulate curiosity. To enable them to actively , active participation in learning. The play of imagination and creativity of students, the “static” content to “activities” of the image of intellectual development of students, training students to observe, thinking, problem solving ability, to achieve optimal classroom teaching, are is of great significance. but in the selection and use of multimedia, we should pay attention to the “degree” to grasp, and only proper use, will play the advantage. after all means of multimedia technology, but only a means.

Cooperative learning is that students in the group together 5in order to complete the learning task, a clear division of responsibilities of mutual learning. cooperative learning reflects new curriculum ideas. What in the teaching process is not cooperative learning groups, according to the needs of students and teaching organizations. content simply do not have cooperative learning groups, content, leavin
