In primary school mathematics teaching, students' computing ability directly affects teachers' teaching quality and students' learning quality. Therefore, improving students' computing ability has become one of the important topics to be studied in primary school mathematics teaching. In order to effectively improve the calculation ability of primary school students, various measures and methods should be taken. Therefore, simple computing ability is formed on the basis of students' sense of number development and strong computing ability. The improvement of simple computing ability can promote the development of students' sense of number and enhance their computing ability. How to improve students' simple computing ability?
First, master verbal arithmetic and cultivate the agility of students' thinking.
Accurate and fast problem-solving thinking activity is an important manifestation of quick thinking. Grasping the basic training of oral arithmetic can improve students' ability to use rules. Two points should be paid attention to in oral calculation: first, not writing is not conducive to the improvement of oral calculation ability and the cultivation of students' thinking agility. Secondly, there should be speed requirements when calculating, so that students have a sense of urgency. It is a good method to use slats for oral arithmetic training.
Second, grasp the whole and cultivate the flexibility of students' thinking.
The flexibility of thinking embodies the flexibility of thinking activities in many aspects, such as the choice angle, application method and development process. Mainly focus on the following aspects of training. (1). That is, add up these numbers to become an integer ten, an integer hundred, and so on. And then calculate them. That is, rounding method, more increase and more decrease or more increase and less decrease. (2) integration. It is to disassemble one number in the operation and operate it separately from another number to facilitate the rounding operation. (3) estimation. Estimation can improve students' self-checking ability, improve the correct rate of quick calculation and help cultivate students' thinking flexibility. Estimation: Generally, some figures are estimated to be the nearest whole ten, whole hundred, etc. Estimate the approximate result first, and then answer accurately. Secondly, it is tested by estimation.
Third, be diligent in induction and cultivate the profundity of students' thinking.
Refers to the abstraction and logical level of thinking activities. Mainly focus on the following aspects of training. (1). According to the rounding characteristics, two or more numbers are combined, which is convenient for oral calculation and mental calculation. (2) turn. Transform the operation method, simplify the complex and popularize mental arithmetic. Guide students to sum up the rules and deepen their understanding and memory of knowledge. (3) change. Is to change the operation order and change the constant value. According to the definition of law, change the operation symbols and data to promote students to master knowledge. One is to master the inverse operation, and the other is to master the special properties and deepen the deep understanding of the topic, thus cultivating the profundity of students' thinking and improving their skillful calculation ability.
Fourth, ask questions carefully to cultivate the originality of students' thinking.
The originality of thinking is generally manifested in thinking more and thinking well, being novel and unique. Mainly master the following skills for training.
1, omitted According to the particularity of 0 and 1 in operation, the calculation steps are omitted, thus cultivating students' unique innovative thinking.
2. eliminate. Eliminate two corresponding numbers (such as +3 and -3), reduce operation steps and cultivate students' innovative thinking.
In a word, in primary school mathematics teaching, students' computing ability cannot be achieved overnight. As a teacher, we should first apply the calculation rules and laws freely, so that we can be handy in guiding and improve the effect. At the same time, training should be persistent, and it is difficult to get results by fishing for three days and drying the net for two days. In the teaching of calculation, we should constantly think and explore, not just calculate for the sake of calculation, but combine with the life reality and emotional attitude advocated by the current new curriculum standard to avoid the singleness and boredom of calculation. Therefore, only through simple operation and paying attention to the cultivation of students' thinking ability can we effectively improve the teaching quality and promote the improvement of students' computing skills.
