Question 2: Is it necessary for primary school students to learn abacus mental arithmetic? I am a primary school math teacher and have taught seven first-year students. The so-called abacus mental arithmetic is to teach children to solve oral arithmetic problems with abacus. Because there are many formulas for abacus calculation, it can help some children who can remember and use formulas to improve the calculation speed. However, because children who often learn abacus mental arithmetic are young, they are all mandatory memories, and they will be completely forgotten if they don't use them for a while. More importantly, the arithmetic of abacus is different from that of primary school students (which we often use at ordinary times). According to my experience, the help of mental arithmetic with blood beads to children's mathematics learning is between 5%- 10%. Most children's mental arithmetic with blood beads is not helpful to learning mathematics, and some children's mental arithmetic with blood beads hinders the learning of general calculation in mathematics. Therefore, it is suggested that this parent should think twice before letting his children learn abacus mental arithmetic! If you have any other questions about primary school mathematics, you can leave a message on my tree directly!
Question 3: Is it useful to learn abacus mental arithmetic? Are there any negative effects? The so-called abacus mental arithmetic is to teach children to solve oral arithmetic problems with abacus. Because abacus has many formulas, it can help some children who can remember and use it to improve the calculation speed. However, because children who often learn abacus mental arithmetic are young, they are all mandatory memories, and they will be completely forgotten if they don't use them for a while. More importantly, the arithmetic of abacus is different from that of primary school students (which we often use at ordinary times). According to my experience, the help of mental arithmetic with blood beads to children's mathematics learning is about 5%- 10%. Most children's mental arithmetic with blood beads is not helpful to learning mathematics, and some children's mental arithmetic with blood beads hinders the learning of general calculation in mathematics. Therefore, parents are advised to think twice before letting their children learn abacus mental arithmetic!
Question 4: Is it necessary for children in grade two to learn abacus mental arithmetic? It depends on your motivation to let your children learn. If it's just to learn arithmetic, it doesn't feel necessary. Generally, children are also top accountants. It won't be a big problem to hurry up and slow down. You don't want your children to take part in the quick calculation competition. But if you want children to exercise their thinking ability, develop their intelligence and cultivate good habits, you can send them to study, but you should assist and supervise them according to the requirements of teachers. Otherwise, children just learn to calculate and can't achieve the good results you want. It is important for children to keep practicing their learning methods. If they keep practicing, they will benefit a lot from studying other subjects.
Question 5: Is it necessary for children to learn abacus mental arithmetic? To be honest-absolutely not!
I found it useless when I got to middle school! -I forgot what I learned!
Unless you take the Olympic dead end!
This is all because some people use their parents' desire to cheat money! But the parents who were cheated left after wave ―― speechless!
Question 6: Is it necessary for children to learn abacus mental arithmetic? It is not necessary for children to learn abacus mental arithmetic, but it should be decided according to specific conditions and conditions.
In the study of abacus mental arithmetic, in principle, the younger the better, because the growth of human intellectual brain cells has been completed before the age of three, and it has grown to 100 from the age of four to 12. 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. On the other hand, adult brain cells, because of their rigidity, cannot make their intelligence, thinking ability, memory and imagination grow more actively with the help of abacus mental arithmetic, that is, they cannot produce mental arithmetic images.
However, in the physiological structure, abacus mental arithmetic learning belongs to highly technical operational learning, and the coordination and balance of the body are extremely important. When learning at a young age, because the nerve coordination and sensory balance of the small muscles of the hand have not yet been finalized, they often have poor posture or poor pen grip. In addition, the teachers in the market are mixed and the teaching concept is not properly guided, which is more likely to destroy the learners' "sense of number" and may get twice the result with half the effort in the future.
Therefore, it is suggested that the entry age of learning should be between 4- 12.
Question 7: Do you want to learn abacus mental arithmetic? You can learn it. It is better and more convenient to learn abacus mental arithmetic.
Question 8: Is it necessary for a 4-year-old child to learn abacus mental arithmetic? One: Four years old is the best time to learn abacus mental arithmetic. Before the child's brain matures, the left brain is weak in abstract thinking and insensitive to numbers. The right brain's image thinking ability is very developed, especially before the age of 6. During this period, children can form the image of the right brain with the help of abacus, learn mathematics easily, and fully develop children's right brain function.
Two: In the process of children's abacus mental arithmetic learning, children's eyes, ears, hands, mouth and brain need to participate in a series of processes, and the left and right brains must coordinate to complete the whole process, which effectively promotes the balanced development of the left and right brains. Let children's attention, memory, imagination and creativity be better. It is easier to learn other subjects after primary school. The most obvious example is that English words are remembered quickly, Chinese texts are easy to recite, and calculation problems are easier. Teachers like it, classmates envy it, and children's self-confidence is enhanced, their interest in learning is stronger and their thirst for knowledge is higher.
Third, there are many ways and methods to develop the potential of human brain, and abacus mental arithmetic education is one of them. Because abacus mental arithmetic is closely related to basic education, especially for young children, it can lay a good foundation for the all-round development of brain function. Although computers can liberate people's labor force and help people do many dangerous and tedious jobs, primary school students rely too much on computers, which will affect their computing ability and thinking ability over time. For example, American children have been accompanied by computers since childhood, and their computing ability is generally low, which has caused concern in the United States. It is stipulated that primary school students should not use computers (equipment) to learn mathematics, and efforts should be made to introduce China's abacus and mental arithmetic into basic education. Because abacus mental arithmetic has its uniqueness in information storage and transmission, it can integrate input and output. Although its storage capacity can't be compared with that of a computer, when calculating with abacus, input information and display the calculation results. This is the characteristic of "counting beads". This feature is not available to computers, and it is incomparable to other computing tools. Therefore, the role of abacus mental arithmetic in basic education is immeasurable.
It is the need of the times and the development direction of abacus mental arithmetic to incorporate it into mathematics textbooks. Only with the simultaneous development of abacus mental arithmetic, mathematics and computer can we cultivate more cross-century talents with strong thinking ability and modern knowledge, create and invent more high-tech products and better serve mankind.
Question 9: My child is too slow in arithmetic. Do you think it is necessary to learn abacus mental arithmetic to make the best use of it?
