The supermarket is one of the most familiar scenes for children. Children’s attention are attracted by the dazzling array of items on the shelves. The “customer” picks the required goods into the wooden purchase car. The “cashier” settles accounts at the cash register and exercises computational skills to stimulate the children’s interest in mathematics. Strong sense of experience and practice make the children learn how to negotiate and cooperate, and understand the real working and life status of various characters. Being able to play different professional roles every time is one of the reasons why the mini town has a high rate of return.
