simple calculation is often boring and students are easily bored. Therefore, according to the psychological characteristics of the lower grade students who are active and competitive, we can use a variety of training forms to replace the previous single form of practice. For example: training with games, competitions, etc; Driving trains, rushing to answer questions, breaking through barriers, etc. Various forms of training, not only stimulate students' interest in learning, but also make every student actively participate, so as to get twice the result with half the effort. Senior students can explain the principle of problem-solving more, let students understand the context of problem-solving ideas, know the reasons for this problem-solving, deepen the understanding, will improve interest< Second, pay attention to the training of oral arithmetic
oral calculation is the basis of written calculation, which requires not only accuracy but also speed. The formation of oral arithmetic skills and the improvement of speed can not be achieved by one or two days of training, but by constant training. In my opinion, the effect of mental arithmetic three minutes before class is very good. Before each class, prepare ten oral arithmetic questions for students to rush to answer, or let students write in a small book, check the answers in a unified way, make a summary every other time, and praise and reward the excellent students. The enthusiasm of students has been improved, and at the same time, they will pay attention to the correct rate. Of course, remember some common values, such as 2 π、 three π、 four π……， 112, 122, 132... And so on, which have a very good effect on speeding up the speed and accuracy of oral calculation< Thirdly, strengthen the training of estimation
many problems in daily life don't need very accurate results, so we can use estimation to solve them. In this way, the speed is accelerated, and it does not affect the actual operation. When encountering such problems, let the students estimate as much as possible. In addition, even in the calculation of accurate results, the estimation will also play a monitoring role. Every time we finish a question, we can use the method of estimation to verify its correctness< 4. Pay attention to quick calculation and skillful calculation
quick calculation and skillful calculation are what we usually call simple calculation. The correct use of simple methods can not only improve the speed of problem solving, but also make the problem solving simple and improve students' self-confidence. The teacher can teach some basic laws first, let the students answer the questions, in the example of some calculation problems, let the students find the appropriate simple method. This requires students to have a clear grasp of the basic law of operation, especially the scope of its application. For example, multiplication has distributive law, but division does not. This requires students to divide by a number into its reciprocal, in the use of distribution law for calculation.
