After 1.5 years of study, children can master abacus mental arithmetic well, which will not conflict with learning elementary school arithmetic after school. From this perspective, children should not be over 5 years old at the latest.
First, what is abacus mental arithmetic?
Abacus mental arithmetic is abacus mental arithmetic. Abacus calculation, using abacus as a tool, is used to calculate four operations of addition, subtraction, multiplication and division of multi-digits, square roots and other problems.
Second, the training function of abacus mental arithmetic
Training of direction and attention, attention range, attention continuity, attention stability, hand-eye coordination and thinking ability.
Third, mental arithmetic is suitable for people.
In principle, the younger you learn abacus mental arithmetic, the better, because the growth of human intellectual brain cells has been completed before the age of three, and it has increased from four years old to 12 to 100%. The learning process of abacus mental arithmetic must strengthen the establishment of images through the proficiency of abacus operation, and the growth of brain cells is the driving force of image establishment.
Adult brain cells have been stereotyped, so it is impossible to make their intelligence, thinking ability, memory and imagination grow more actively with the help of abacus mental arithmetic learning, that is, they cannot produce mental arithmetic images.
Fourth, the learning method of abacus mental arithmetic
In the process of abacus mental arithmetic teaching, abacus is the foundation. Through the operation of true abacus, let learners know the changes and methods of the four operations. The study of abacus can master the calculation ability and memory ability skillfully.
How to create the best teaching and training effect with the least time and energy should do the following three things:
1, we should handle the relationship between "accuracy" and "speed".
2. Pay attention to the training of listening.
3. Strengthen abacus operation.
Five, the characteristics of abacus mental arithmetic
Abacus mental arithmetic has the characteristics of "five liters decimal system", which greatly reduces the carrying difficulty. Abacus mental arithmetic has the characteristics of operation model, which is helpful to improve children's computing ability.
The operation of abacus mental arithmetic is a collaborative process of various sensory organs and motor organs, which requires the close cooperation of eyes, ears and mouth. So as to promote the development of the corresponding parts of the cerebral cortex closely connected with it and improve the intelligence level of children.
Sixth, the timetable for learning abacus mental arithmetic:
1, the time to start learning abacus mental arithmetic must be more than one and a half years from primary school, so as to ensure that children can firmly master abacus mental arithmetic before going to school, and it will be easier to learn elementary school algorithms after going to school.
2. Have classes twice a week before school. Don't miss class. Ensure that you finish your homework half an hour after class every day and ensure the quality of your homework. This can ensure the learning effect.
3. The first and second grades of primary school have classes once a week to learn new technologies and consolidate old knowledge.
4, the third grade of primary school, once every two weeks, review and consolidate.
5, the fourth grade of primary school, once a month, review and consolidate.
