In the first grade, students began to learn the calculation of Jiao Yuan's score. Jiao Yuan fen is the basic unit of RMB, where 1 yuan equals 10 angle, and 10 angle equals 10 angle. In order to help students better master the calculation of Jiao Yuan-fen, teachers usually teach some simple and easy-to-remember formulas.

The following is a common formula for calculating Jiao Yuan score:

One dollar, ten cents, ten percent, ten cents, ten cents.

This formula means that 1 yuan equals 10 angle, 10 yuan equals 100 angle, 1 angle equals 10 point, 10 point equals 1 point. The advantage of this formula is that it is easy to remember and understand, which is suitable for the cognitive level of first-year students.

In addition to formulas, teachers can also help students master the calculation of Jiao Yuan score through practical operation. For example, students can do practical calculation exercises with small notes and coins, or deepen their understanding and memory of Jiao Yuan's score through games and other forms.

In a word, Jiao Yuanfen is the basic unit of RMB and the basic knowledge that first-year students must master. Through formula practice and practical operation, students can better understand and master the calculation method of Jiao Yuanfen, and lay a solid foundation for future mathematics study.
