Learn mental arithmetic, okay?

? It is not good for children to learn abacus mental arithmetic, which may make them lose interest in calculation, thus affecting their study and grades.

? Like my generation, the post-80s and post-90s are basically abacus in primary school. In fact, abacus mental arithmetic is a mental arithmetic method based on this. What I was most afraid of at that time was being calculated, such as: one up one, two up two, three down five to two, four down five to one … which made me feel very headache. Now abacus mental arithmetic does not need the help of abacus, that is, children can simulate abacus in their minds to calculate. Some children will close their eyes, talk eloquently and fiddle with their hands like an abacus, which will bring the following disadvantages:

Affect mathematical calculation

? Yes, you are not mistaken. Although abacus mental arithmetic can improve the calculation speed after learning, it will easily affect children's mathematics learning and calculation accuracy after a long time. Because mental abacus calculation is a tricky method, some children don't want to take the time to check when calculating, as long as they have already made the answer. This can easily lead to low-level mistakes.

? When I tutor my nephew to do math calculation, I always ask him to use vertical calculation step by step, and check the calculation, so that he can understand the importance of basic problems, ensure the correct rate, and not be opportunistic.

Not practical.

? Abacus mental arithmetic is just a quick calculation skill, which is helpful for calculation, but it can't improve children's logical thinking ability and number-type combination ability. Therefore, it is basically ineffective to improve math scores by learning abacus mental arithmetic.

? When I was tutoring my nephew, I found that those who have poor math scores (my nephew is) often have poor understanding of fill-in-the-blank questions and application questions and can't understand the meaning of the questions, but learning abacus mental arithmetic can't improve this situation.

Lose interest in learning

? There is still some difficulty in learning abacus mental arithmetic. Some children find it difficult to master after learning, and they will be afraid of difficulties. They think that mathematics is too difficult and will even affect the study of textbooks.

To sum up, the disadvantages of abacus mental arithmetic are obvious, but it doesn't mean that it has no effect at all. In fact, for children with good math scores and spare capacity for learning, it is still beneficial to learn abacus mental arithmetic, but it is best for children to have their own willingness to learn. After all, interest is the best teacher.

? Therefore, mental arithmetic is not a necessary option for children to learn mathematics. Parents should decide according to the situation when they let their children learn, otherwise it will easily increase the burden on their children, waste time and money, and finally it will not help their children learn, and the loss will outweigh the gain.
