Article: Many adults in the United States can remember crying the nursery rhyme in the street "Hot cross buns!" But only a few people realize this was an early form of advertising. Written advertisements probably began with hieroglyphics more than three thousand years ago, but only a few people could read these symbols. So merchants made signs with pictures or hung their tools over their doors to identify their businesses. In the time of the Roman Empire, wall paintings were a popular form of advertisement. An ad for a play, or some other performance was painted on part of a building or on a wall around a city. People often advertised a house for rent or a freshwater bath in this way, too. Today, large wall signs are still used for outdoor advertising. But outdoor advertising is only a small fraction of the total advertising. About forty per -cent of all ads are printed in daily newspapers. Radio commercials also provide this kind of information. Some people think they are the best form of advertising because radio broadcasts reach almost everyone in a nation. Advertisements in magazines and on television reach many people, too. However, usually only large companies can advertise on a national network, because TV commercials shown across the country can cost many thousands of dollars. Then there are ads that are almost part of daily living. If you use public transportation, you will see large printed ads, called ear cards, on buses and taxis and in trains. Ads are painted on the trucks that deliver products people are buying or selling.

They dried the paper in the sun. The Chinese kept their secret of how to make paper until a war with Muslims in the ninth century. The art of papermaking soon spread throughout the Muslim world. The Mayan Indians in Central America and Pacific Islanders also discovered how to make paper, but their knowledge never spread to the rest of the world. For centuries, all paper was made by hand.

Article: Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly. The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance. In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics. Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest it. Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A savings account is an excellent way to learn about the power of compound interest . That may not seem like a lot. But over time it adds up.
