Oral mobility applications:
Primary school students' oral arithmetic is an educational application based on tablet computer, which is aimed at primary school students from grade one to grade six. It makes full use of the advantages of tablet computer and provides a comfortable, interesting, convenient and practical oral arithmetic training platform for primary school students.
Let children easily complete oral arithmetic homework, carry out oral arithmetic training anytime and anywhere, improve their oral arithmetic ability, and also free parents from the work of exporting and checking oral arithmetic questions for their children every day.
The learning purpose of oral arithmetic:
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.
The method of oral calculation:
1, 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. ?
2. Is it 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. ?
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.
