With the development of the mobile Internet and mobile payment(支付), more and more children are not using paper money now.
A report shows 86% of the people in China use smartphones to pay. For students, they seldom use paper money in their daily life. They may only see it when they get lucky money during the Spring Festival. When they need to buy something, they usually don’t reach into their pockets for paper money. They use their smartwatches. As a result, many children ask their parents, “Why not save money in the mobile wallet on smartphones or smartwatches?”
Hearing the question from their kids, a large number of parents start to worry. “Our children don’t have a sense of money. For them, money is just numbers. They have no idea where money comes from or how difficult one makes money. This may cause big problems when they grow up,” one mother said.
To solve the problem, a few primary schools in some cities begin to give special Maths classes to help students learn more about money. In the classes, teachers show paper money and coins(硬币) to students and teach them the basic units like yuan, jiao and fen. What’s more, the teachers ask the students to do simple calculations(计算): from jiao to yuan or from yuan to fen. Mr Wang, a head teacher, said, “Most children know little about money, so we need to help them. It’s a 
challenging job, but the classes will be helpful to them in the future.”
