Fast center is the only way to perform simple operations without any physical objects, abacus, fingers, chessboard and charts.

The arrangement and difficulty of the textbook "Quick Mental Arithmetic" are closely related to the elementary school mathematics syllabus and junior high school algebra, which is simpler than the elementary school textbook. It simplifies the written calculation and strengthens the oral calculation. It is simple, easy to learn and interesting. After a short period of training, primary school students can write answers directly by adding, subtracting, multiplying and dividing, not vertically.

Special effect of quick mental arithmetic

I have learned all the multiplication, division, addition and subtraction of any multi-digit number above grade three.

Addition and subtraction of high two digits, multiplication of two digits, division of one digit.

First grade, multi-digit addition and subtraction.

In kindergarten, children in large classes can learn the addition and subtraction of multiple digits, the carry and addition of multiple digits, such as 5869+35 16, and the abdication of multiple digits, such as 8 185-6938. For preschool children, it is helpful to learn quickly in kindergarten in the future.

Children no longer use draft paper to do their homework, but write answers directly.

Quick mental arithmetic is different from abacus mental arithmetic and palm mental arithmetic. Fast Heart was invented by Niu Hongwei, a teacher from Xi 'an. He obtained patent certificates from People's Republic of China (PRC) and China National Intellectual Property Administration. ZL200830 1 174275。 It is protected by the patent law of China people. ), mainly through certain rules in textbooks, train children to perform fast operations of addition, subtraction, multiplication and division. "Quick mental arithmetic" is helpful to improve the order, logic and sensitivity of children's thinking and behavior, and train children's eyes, hands and brain to react and calculate synchronously.

Fast mental arithmetic teaching mode that is really synchronized with primary school mathematics textbooks;

1: learning algorithm-writing training. At present, the education system in China is exam-oriented education, and the standard for testing students is exam transcripts. Then the students' main tasks are to take exams, answer questions and write with a pen. Writing arithmetic training is the main line of teaching. Consistent with the mathematical calculation method in primary schools, physical calculation is not used, and both horizontal and vertical, and even increase and decrease can be used freely. Writing with a pen is a way to start intelligent express delivery.

2. Clear arithmetic-arithmetic spelling. Writing questions with a pen should not only let children know arithmetic, but also let them know arithmetic. Let children understand the arithmetic of calculation in spelling and break through the calculation of numbers. The child completes the calculation on the basis of understanding.

3. Practice speed-speed training, it is far from enough to use a pen to calculate problems. There should be a time limit for oral calculation in primary schools. It takes time to tell whether it is up to standard, that is, there are not enough calculation questions, mainly to speed up.

4. Enlightenment wisdom-intellectual gymnastics is not a simple study and calculation, but focuses on cultivating children's mathematical thinking ability, fully stimulating the potential of the left and right brains and developing the whole brain. After rapid mental arithmetic training, preschool children can deeply understand the essence of mathematics (including), the meaning of numbers (cardinal number, ordinal number, including) and the operation mechanism of numbers (addition and subtraction of numbers with the same number), so as to master the way of mathematical logic operation.
