Which is better, oral arithmetic or application problems?
Do oral calculations.

From the first day to the third day, the most important thing for children's mathematics is oral calculation and application problems. Oral calculation is the foundation, and application problems are mathematical thinking. Interesting oral math problem card This set of books is characterized by automatically writing calculation problems and application problems on one page, which can not only exercise children's computing ability, but also cultivate children's mathematical thinking.

Application problem is to describe relevant facts in language or words and reflect some mathematical relationship (such as quantitative relationship, positional relationship, etc.) ) and solved an unknown number of problems. Each application problem includes known conditions and problems. In the past, China's application problems usually required narrative to meet three requirements: no contradiction, that is, conditions and problems could not be contradictory. Completeness, that is, the condition must be sufficient to ensure that the value of the unknown quantity can be obtained from the condition. Independence, that is, several known conditions cannot be deduced from each other. Math application problems in primary schools are usually divided into two categories: simple application problems that can be solved in one step by adding, subtracting, multiplying and dividing. Complex application problems that need two or more operations to solve.
