Divide the unit "1" into several parts on average, and the number representing such a part or parts is called a score. The number representing this share is called the fractional unit.
Fraction consists of numerator, denominator and fractional line, with numerator above and denominator below. The result of division can be expressed in fractions. When a number is divided by another number, it can be expressed as a fraction when the number is not an integer.
Dividend is numerator, divisor is denominator, and fractional line is equivalent to divisor. Scores are divided into false scores and true scores. False scores are divided into fractions and integers.
The numerator and denominator are coprime, and this score is called simplest fraction. To determine the denominator, divide the decimal into several decimal places, and then look at the number after the decimal point, which is the numerator. If there is an integer, it becomes a fraction, and the fraction is read as several fractions.
The ratio of integer a to integer b can be expressed as a fraction. A score can also represent the score of one number to another, or the ratio of one event to all events.
From "inductive combination method of primary school mathematics" to "four-step method of cultivating innovative spirit of primary school mathematics", Wu Zhengxian has created a math class that children like, and her math teaching is called "melody of love and beauty". Won the honorary title of national model teacher.
After working for more than 30 years, she has never left the classroom. "Everything is for children" is the core of her educational thought, and "creating a classroom that children like" is her goal for many years.
