In the second book of grade two, mathematics and division account for a considerable proportion, and the concept of average score is what children must master. In the actual teaching process, it is found that many children are confused about the content of the average score. Sometimes even if the topic is done correctly, I still don't understand the meaning of the formula. Once the topic is changed, I won't do it.

In-table division means that the quotient can be obtained by multiplication formula. A simple division is calculated according to the multiplication in the table. According to the meaning of multiplication and division, some simple application problems of multiplication and division are solved. Dividend/Divider = Quotient, Divider/Quotient = Divider, Divider × Quotient = Divider.

Division is one of the four operations. Given the product of two factors and a non-zero factor, the operation of finding another factor is called division.

Division of two numbers is also called the ratio of two numbers. If ab=c(b≠0), the operation of finding another factor A by multiplying the product C and the factor B is division, which is marked as c÷b and pronounced as C divided by B (or B divided by C). Among them, c is called dividend, b is called divisor, and the result of a operation is called quotient.

Division: as long as it is an average process, it can be expressed by division formula. The number before the divisor is called the dividend, and the number after the divisor is called the divisor, and the result is called the quotient. Dividend = quotient. The way to find the quotient: use the multiplication formula. Look at the divisor first, think about the formula, then look at the divisor and decide which formula to use. (think about it: multiply the divisor by a few to get the dividend, and what is the quotient. )
