Some parents think abacus mental arithmetic is of great help to children's mathematics and can perform arithmetic operations quickly;
Some parents think that abacus mental arithmetic can get results quickly, but children don't just calculate when they learn mathematics, and there is no need to learn calculation specially.
In my opinion, exposing children to abacus mental arithmetic prematurely is only beneficial to the calculation speed in the short term.
Today, let's objectively analyze abacus mental arithmetic.
1, inconsistent algorithms will lead to confusion.
The algorithm of abacus mental arithmetic is from high position to low position, from left to right,
However, in the primary school curriculum, arithmetic is calculated vertically, that is, from low position to high position and from right to left.
These two completely different or even completely opposite calculation methods are particularly easy to cause confusion in children's way of thinking. When they encounter problems, they don't know what way to choose.
The better you learn abacus mental arithmetic, the harder it is to correct it.
2. Learn abstract calculation methods too early.
Premature exposure to abstract mathematical calculations, especially when children don't understand, learning abacus mental arithmetic, skipping the key step of understanding meaning, has no small obstacles to future development.
Mathematics itself is very abstract, unlike biology and geography, which can be learned by physical objects. The abstraction of mathematics makes it impossible for children to understand it in their own minds.
In the process of children's learning mathematics, the process from concrete to abstract is essential. The purpose of this process is to make children understand the meaning of mathematics.
Suddenly skipping the specific understanding level and directly making abstract calculations will not have a big impact in the short term, but over time, short board exposure is inevitable.
3. The limitations of mathematical thinking
Children who have learned abacus mental arithmetic have an obvious feature. They are very sensitive to numbers, but they are very sensitive to mathematics.
The reason for this situation is that they have been doing mathematical calculations for a long time, and they have become numb to calculation and lost their curiosity about mathematics.
With the increasing difficulty of mathematics, children's lack of curiosity about mathematics will lead to complete lack of interest in mathematics and unwillingness to take the initiative to learn.
There is no shortcut to early mathematics education. Parents should treat early education cram schools rationally and choose courses suitable for their children.
