Oral calculation: mental calculation and oral calculation are carried out at the same time. Oral arithmetic is to calculate with the brain and remember the results at that time with oral narration. This method is used for quick calculation, and regular practice is helpful to improve intelligence. It has also become the mainstream calculation method today. Also called "mental arithmetic". One of mathematics teaching methods. A calculation method based on thinking and language activities without any tools. It can train students to calculate quickly and develop their attention, memory and thinking ability. Proficiency in verbal calculation is helpful for written calculation and is convenient for daily use. [ 1]

Discrimination of mobile application of oral arithmetic in primary schools

Detailed explanation

Oral calculation-fast heart is the only way to perform simple operations without any physical objects, and you don't need an abacus or fingers. Oral calculation-quick mental calculation-a teaching mode that is really synchronized with primary school mathematics textbooks.

The arrangement and difficulty of oral arithmetic-the textbook of quick mental arithmetic is closely related to the syllabus of primary school mathematics, which accords with the quick calculation of junior high school algebra and is simpler than the textbook of primary school. Simplify written calculation and strengthen 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.

Oral arithmetic-the peculiar 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 multi-digit addition and subtraction, which is tailor-made for preschool children, so that they can calculate the primary school mouth in advance. It is helpful for children to learn mental arithmetic quickly in kindergarten to go to primary school in the future.

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

remove doubts and misgivings

Oral arithmetic and quick mental arithmetic are different from abacus mental arithmetic and palm mental arithmetic. The fast mental arithmetic invented by Niu Hongwei, a teacher in Xi 'an, mainly trains children to do addition, subtraction, multiplication and division quickly through certain rules in textbooks. "Quick mental arithmetic" helps to improve the order, logic and sensitivity of children's thinking and behavior, and trains children's eyes, hands and brains to react quickly. The calculation method is consistent with that of primary and secondary school mathematics, so it is very popular with children and parents. Oral arithmetic and quick mental arithmetic: a teaching mode that is truly synchronized with primary school mathematics textbooks;

1: Knowledgeable algorithm

Written calculation training, China's current education system is exam-oriented education, and the standard for testing students is the test report card. 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, it does not use any physical calculation, and can be used freely horizontally and vertically, even adding and subtracting. Computing with a pen is the golden key to opening an intelligent express train.

Step 2 be clear and reasonable

Try to find out. Children should not only learn arithmetic, but also know it. Let children understand the calculation principle and break through the calculation of numbers in spelling. The child completes the calculation on the basis of understanding.

Step 3 practice speed

Speed training, it's not enough just to use pen to calculate problems. There is definitely a time limit for primary school oral arithmetic. It takes time to tell whether it is up to standard, that is, it is not enough to calculate problems, mainly to speed up.

4. Enlightenment wisdom

Intellectual gymnastics, not simply learning and calculating, 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), the operation mechanism of numbers (addition and subtraction of numbers with the same number) and the way of mathematical logic operation, so that children can master the method of dealing with complex information decomposition and develop divergent thinking and reverse thinking. The child's brain works fast.

Mobile application of oral arithmetic in primary schools

"Primary school students' oral arithmetic" is an educational application based on tablet computer, which is developed for primary school students from grade one to grade six. It makes full use of the advantages of tablet computer to provide a comfortable, interesting, convenient and practical oral arithmetic training platform for primary school students, so that children can easily complete oral arithmetic homework and conduct oral arithmetic training anytime and anywhere, improve their oral arithmetic ability, and free parents from the work of exporting and checking oral arithmetic questions for their children every day.

Why use

Oral arithmetic is an important part of primary school mathematics learning, and it is also an important content of primary school students' mathematics homework and mathematics examination. The editorial board of Curriculum Standards for Full-time Compulsory Education pointed out: "Cultivating students' awareness of oral calculation, estimation and quick calculation plays an important role in developing students' computing ability and cultivating a good sense of numbers." In order to help primary school students finish their oral arithmetic homework quickly and improve their oral arithmetic ability, and also to help parents better coach their children.

Applicable people

At present, the 1-6 grade oral arithmetic problem cards in the People's Education Edition of the software provider and the Hebei Education Edition are all based on iPad tablets, which are suitable for parents who have the conditions to buy to help primary school students with oral arithmetic training.
