The knowledge of the course "Understanding Branch Names" is relatively simple, but rather boring. How to stimulate students' interest in learning is a problem I have been thinking about. Students in grade two are more interested in animation, so I finally choose to import animation from digital textbooks.

On the one hand, it can stimulate students' interest in learning, on the other hand, it can directly use the animation of digital teaching materials, greatly reducing the burden of preparing lessons. For the production of animation, it is more difficult and takes more time.

In teaching this lesson, it takes a little more time to start introducing the division formula. Students didn't understand the meaning of the division formula well in the last lesson "Preliminary Understanding of Division", which is a difficult point for students to learn, but the knowledge points of the names of each part of the division formula are relatively simple.

Department:

Is one of 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), using the product C and the factor B to find another factor A is division, written as c÷b, and read 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.

In mathematics, when the first-level operation (addition and subtraction) and the second-level operation (multiplication and division) are in the same formula at the same time, their operation order is multiplication and division first, then addition and subtraction. If there are parentheses, the order of operations at the same level is from left to right. Such operations are called four operations.
