First, it is thinking graphic mathematics.
The second is the rapid calculation of hand and brain.
1, thinking graphic mathematics
Thinking graphic mathematics pays attention to children's physical operation, and uses intelligent arithmetic and spelling devices to let children manipulate the relationship between numbers. Addition is to play two numbers together, and subtraction is to separate, subtract and hide. With vivid stories, let children understand the principle of calculation in listening to stories. The method of making up ten, which is taught by the primary school teacher, makes the calculation process simpler. First, change 8 to 10, and the rest of the tiger means 1 1. The whole calculation process is done with a speller.
Thinking diagram mathematics is enough for children below grade three in primary school, because it not only solves arithmetic, but also solves calculation, so Xugong's mathematics education has been highly concerned in the world, and has been introduced to various countries, which has made the number invented by China truly go international, and also made China people write a colorful stroke in the history of mathematics. Thinking schema mathematics in number element education is enough to lead the world.
2, hand and brain fast calculation
Why did you upgrade the textbook to quick calculation? First, analyze the structure of the human brain. The human brain is divided into left brain and right brain. The left brain is mainly engaged in logical thinking and the right brain is mainly engaged in image thinking. It is the source of creativity and the center of art and experience learning. The storage capacity of the right brain is 6.5438+0 million times that of the left brain. There is a corpus callosum connection in the middle of the left brain. 2 to 7 years old is the golden age of children's intellectual development. The brain capacity of adults is 1300 grams, and that of children before the age of 2 is only 300 grams.
2 ~ 7 years old is the best time to increase adult brain capacity, reaching 70% of adult brain capacity, and 7 ~ 17 years old increases adult brain capacity. If we grasp the sensitive period of the rapid expansion of children's brain capacity from 2 to 7 years old and develop their left and right brains, it will lay a good foundation for their future study and life.
