One of the earliest was called “tally sticks”. Each “stick” (or pebble, or other counting tool) stands for a thing we want to count, such as an animal or a bag of rice. For each animal we want to count, we draw one stick. This is called a “one-to-one correspondence”. Tally sticks are easy to understand, but it can take a long time to write down large numbers. To write “1,000”, you have to draw a thousand tally sticks! / Later, people created faster ways of writing numbers. One such system developed in ancient India. Instead of using tally sticks, people began using different abstract symbols to represent different numbers. Researchers do not know exactly how this happened, but some believe that the sticks slowly turned into symbols over the centuries. These Indian numerals became popular, and people in the Arab world started using them too. Thanks to the Arabs, this way of writing numbers spread to Europe and across the world. Nowadays, they are known as Arabic numerals. / The ancient Romans wrote numbers in a different way. They used letters from their alphabet. For example, the number 12 is “XII” (10 + 1 + 1). The Roman numerals used to be the most common way of writing numbers in Europe. Today we still see them in many places, for example, on clock faces, on buildings or in books. But Roman numerals are not as common as Arabic numerals, maybe because they are too difficult to use! 任务一：单项选择 1.What does each tally stick stand for? A.A number. B.A thing we want to count. C.A letter. D.A symbol. 2.Where did the system of abstract symbols develop? A.In Rome. B.In Egypt. C.In ancient India. D.In Europe. 任务二：判断正误(T/F) 3.Roman numerals used letters from their alphabet.

It is a wooden frame with beads on sticks. People move the beads up and down to add, subtract（减）, multiply and divide（除）. / The abacus has a history of more than 600 years in China, but its story began even earlier. In ancient times, people counted with small sticks and stones. Later, those sticks slowly turned into the beads of the abacus. / A good abacus user can work very fast. In the past, shopkeepers in China used it to count money every day. Some old accountants（会计）could move their fingers as quickly as lightning! In 2013, the abacus became a world intangible cultural heritage（非物质文化遗产）. / Today, calculators and computers do most of the counting for us. But the abacus is still useful.

It is hard to imagine a world without it. About 1,500 years ago, Indian mathematicians began to use zero in counting. With zero, people could write big numbers like 100 and 1,000 easily. Zero also helps science and computers a lot. I think zero is small but powerful. It is really an amazing number in human history. 学科网（北京）股份有限公司 $
