Benefits of practicing oral arithmetic:
Oral calculation is also a satisfactory calculation, and it is a calculation method that directly calculates the results through thinking without using calculation tools. Fast and simple, it is the basis of learning other calculations. In our daily life, we can say that there is not a day when we don't have to do oral calculations, especially some simple decimal calculations, which are convenient, flexible and fast.
Oral calculation is the basis of estimation and written calculation. Poor oral calculation ability will inevitably affect the accuracy and speed of estimation and written calculation and the formation of calculation skills. Therefore, to improve students' computing ability, we must do oral calculations well.
Some people may think that in today's advanced technology, advanced computing tools are constantly coming out, and cheap calculators abound. Just press the button on the calculation tool and the numbers will come out. What is the need to learn calculation and oral calculation? In fact, this idea is wrong. Only human wisdom is infinite. Aren't all computing tools invented by human beings?
And this extraordinary ability of human beings comes from the accumulation of knowledge, starting with simple oral calculation. Besides, calculators sometimes break down. More importantly, the solid development of oral arithmetic directly affects the development of students' other abilities and intelligence.
Students should not only listen, but also watch, not only speak, but also remember when doing oral calculations. In a sense, it is an organic combination of four senses: ear, eye, heart and mouth. Oral arithmetic can not only stimulate students' thinking, but also develop students' attention, understanding, memory and expression ability. This is also the main purpose of teaching and the need to cultivate architectural talents.
It is necessary to ensure time and persistently cultivate students' oral expression ability. To improve the ability of oral arithmetic, we should not only train repeatedly, but also train constantly, so that everyone can pass the exam as far as possible. Therefore, it takes 3-5 minutes to train students in oral arithmetic every day, and the training should be organically combined with the classroom content.
For example, when learning "multiplier is the multiplication of two or three digits", you can arrange the oral calculation content of multiplication and addition; When learning "divisor is the division of two or three digits", you can arrange the practice of multiplication and subtraction. This is time-consuming at first, but as long as you practice every day, you can greatly improve students' computing ability.
