【A variety of use for numbers】

It isn't easy for elementary schoolchildren in the lower grades to recognize the difference between the two kinds of numbers.😱

Acknowledging the difference,especially understanding for numbers as a quantity,will become very important when learning fractional number,a decimal point 小数点,and ratio.☝

However,at first,it's important to get used to the scatter numbers.😃

However,some people feel like teaching children one third of centimeter.Oh!As proverb says,haste makes waste.We don't have to make a haste.😃

Without getting accustomed to the scatter numbers,even if we try to teach the children the fraction or decimal point,we can't succeed in them.😺

First of all,we have to make the children understand the four basic operations of arithmetic such as addition,subtraction,multiplication,and division.😃

We make the children figure out integral numbers 整数 in two or three digit 桁 with the four basic operations of arithmetic.😃
