Mental arithmetic formula table jingle video 2 how old is mental arithmetic suitable for children to learn?

Generally, mental arithmetic is over 5 years old (5.5 -6 years old is the most suitable). Why? Most 16-year-old children (about 70%) have reached the junction of intuitive thinking and understanding thinking, which means that many 6-year-old children will start to think slowly and will not say what they saw before.

First, mental arithmetic can guide children of this age to think at this stage and give them a special way of thinking. Generally speaking, mental arithmetic is to solve problems with pictures, which is very helpful for this age. For example, you must have a good imagination and keep the story in your mind, so that the articles written will be more vivid, not to mention learning geometry, because this way of thinking is easy to understand.

Second, it takes a lot of time to learn abacus mental arithmetic. Generally, in kindergartens, children in large classes (or next semester) have more free time to teach, and there is not as much homework as primary one and secondary two. You can also choose to start learning abacus mental arithmetic at the age of 4 (but I personally think it is only suitable for 20% of students).

It is often wrong to enroll children in interest classes.

1, only pay attention to the results and ignore the process.

Parents who learn piano only pay attention to which tune their children have learned; Parents who learn to draw only pay attention to whether their children have drawn a complete picture; Parents who learn abacus mental arithmetic only pay attention to whether their children can be fast; Parents who learn dance only pay attention to whether their children have learned to dance a complete dance.

2. Going to an interest class on weekends is like catching up with the schedule, and there is no parent-child time.

Some parents don't care how much they spend, so they enroll their children in one interest class after another on weekends, such as English, film and television performances, piano and roller skating. Children are busy, so are parents. I didn't spend much time with my children in kindergarten last week, but I spent the weekends in interest classes.

3. Impose your ideal on your children.

Some parents were poor when they were young and did not have the conditions to realize their ideals. After having children, they pinned their ideals on them. For example, he has always dreamed of having a parent with excellent English. He let his children learn English in English classes since childhood, and criticized them if their grades were slightly poor.

4, think that sitting in the classroom is the real learning, ignoring the education in life.

Some parents ignore their own abilities and think that only by taking their children to this class and that class, sitting them in small chairs and listening to the teacher in an appropriate way can they really learn something, but they turn a blind eye to the knowledge in life.

The above is the relevant content and detailed introduction about "abacus mental arithmetic is suitable for children to learn". Abacus and mind are deep learning skills. Of course your children will learn when it is time to learn, but don't force them to learn. It's useless and even counterproductive. Children grow up and need parents to teach them slowly.

Mental arithmetic formula table jingle video 3 abacus mental arithmetic benefits:

1, which accords with the development and movement law of auditory vision.

When learning abacus mental arithmetic, the concrete, intuitive and vivid abacus mental arithmetic in abacus mental arithmetic education, the actions of listening, watching, reading, manual and lightning counting, and the translation of counting beads all conform to the development and movement law of auditory vision, so it is easy to be accepted.

2. Stimulated the enthusiasm and initiative of learning.

When learning abacus mental arithmetic, sometimes reading, sometimes abacus, sometimes listening and watching, sometimes answering grades, and interspersed with group competitions to see who can calculate quickly and accurately, always keep a positive attitude and take the initiative to learn. Abacus mental arithmetic, an educational method, stimulates the enthusiasm and initiative of learning, cultivates the brain function in middle school and becomes smarter.

3. One subject is excellent and many subjects benefit.

The practice of abacus mental arithmetic education in various parts of China proves that there is a significant difference in brain sensitivity between those who study abacus mental arithmetic and those who don't participate in it. The quickness of mental arithmetic, the immediacy of observation, the firmness of memory and the richness of imagination are better than others.

Step 4 cultivate a good mood

Learning abacus mental arithmetic can not only understand the history and culture of our country, but also produce national pride. We can also develop serious and rigorous' study habits' and good self-confidence when studying, and it is the greatest pleasure to concentrate on doing one thing independently.

Disadvantages:

1. There is something wrong with the purpose of children learning abacus mental arithmetic in the first stage.

Most children learn abacus mental arithmetic in order to win prizes and compare in life, which violates the original principle of abacus mental arithmetic and affects children's correct understanding.

2. The algorithm is not uniform with the previous algorithm.

As we all know, abacus mental arithmetic is calculated from high to low, that is, from left to right, while vertical calculation is from low to high, that is, from right to left. It goes without saying that there is a certain conflict between the two.

3. Children's patience

Learning mental arithmetic is boring, and it is difficult for children to sit still. Parents need to review exercises after class, otherwise the course can't keep up. The abacus mental arithmetic course is closely related. If you don't master the last class, you won't be able to keep up with the next class, resulting in a vicious circle.

4, the formation of thinking inertia mode

Because abacus mental arithmetic is a fast algorithm based on abacus mental arithmetic proficiency, which is performed in the brain, and then conditioned reflex is formed, and the result is obtained directly through mental arithmetic, so to learn abacus mental arithmetic well, we must first master abacus mental arithmetic skillfully. This will make some children who can simply add and subtract mental arithmetic, because they can't do mental arithmetic skillfully and can't form mental arithmetic pictures in their minds, so they can't do mental arithmetic.
