Mathematics learning methods and skills
Method 1
Hand-brain quick calculation is to use different human organs to simulate the operation of corresponding components and principles of computers, and to simulate computers to develop the computing and counting potential of human bodies. It is realized by simulating the calculation and counting of computer 0 and 1 theory to single digits, and simulating the way (software) of computer inductive processing information. It is not only a calculation method, but also a method to train people's hands and brains to simulate computer rapid operation and counting.
Method 2
Improving language ability-basic training. The elementary school students' age is different, and the basic requirements of oral calculation are also different. The middle and low grades are mainly in the addition of one or two digits. It is best for senior students to take one-digit multiplied by two-digit oral calculation as the basic training. The specific requirement of oral calculation is to multiply one digit by the number in the tenth place of two digits, immediately add the product of one digit and the number in the first digit of two digits to the three digits, and quickly say the result. This kind of oral arithmetic training, the practice of digital space concept, the comparison and memory training of numbers can be said to be the sublimation training of digital abstract thinking in primary school, which is very beneficial to promoting the development of everyone's thinking and intelligence. You can arrange this exercise in two time periods. One is when reading in the morning, and the other is to arrange a group after finishing homework. Each group is divided as follows: select a digit, and one or ten digits in the corresponding two digits all contain a certain number. Each group has 18 channels. Write the formula first, and write the numbers directly after a few oral calculations. After this continues for a period of time, you will find that the speed and accuracy of your oral calculation will be greatly improved.
