When we don't understand each other's language, we can talk with the help of signs.

    A Frenchman was once travelling in England. He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it, and took out again. He wanted to say. "Bring me something to eat."

    The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused it. He shook his head whenever the waiter brought him something to drink, for drinks are not food.

    When the man was going away, another man came in. This man saw the waiter, and he put his hand on his stomach. That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him.

    So you see, we cannot understand the language of signs as well as we can understand the language of words.

    Once an Englishman named Jack Brown went to Russia for a holiday. He stayed there for several months and then came home again. Some of his friends visited him a few days after he got back. "I had a very dangerous trip while I was in Russia," Jack said to them. "I wanted to see a friend of mine in the country and the bad weather made me very late. So I was still traveling through a forest in a sleigh(雪橇) when the sun went down. It was a long way from my friend's house when about twenty wolves began to follow my sleigh. It was very dark in the forest. There was thick snow on the ground. It was cold, and there were no houses for miles and miles. First I heard the wolves. The noise was terrible! The horses heard them, too. They were frightened and began running faster. Then I saw long, gray forms among the trees, and soon the wolves were near us. They were running very fast, and they didn't seem to get tired like the horses."

    "What did you do?" one of Jack's friends asked.

    "When the wolves got very near," Jack answered, "I put up my gun and shot the first wolf. The sleigh was moving about, but I hit the animal and killed it. Then all the other wolves stopped and ate it, so our sleigh got away from them for a few minutes."

    "Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another of them, and the others stopped once more to eat it."

    "The same thing happened again and again, and my horses became more and more tired and ran slower and slower until, after about two hours, only one wolf was still alive and following us."

    "Wasn't it too fat to run?" one of his friends asked.

    SILVER SPRING, MARYLAND — Student engagement (参与) is a goal in schools everywhere. A teacher in the Washington suburbs has found a way to engage and motivate students — by ringing rhythm and fun to mathematics. The approach works well especially for students who speak English as a second language.

Making math fun

The voice heard in the video belongs to mathematics teacher Jake Scott. Most of the performers are his students. "I use rap because it is something that appeals to the students, and also because music aids memory," Scott explains.

    Scott started using rap videos three years ago. So far he has produced nine, including

Scott started using rap videos three years ago. So far he has produced nine, including YouTube favorites Triangle Experts and Quadratic Formulatic, which have been viewed tens of thousands of times. "It is fun and the whole process is something that students appreciate," Scott says.

    Empowering students

    Blair High School principal Renay Johnson is a big supporter. She even appears in Scott's latest video, Undefined Expressions.

"Mr. Scott is very motivating and engaging for students," Johnson notes. "He enjoys what he does. As you know he engages students and mathematics through music. But he is also our wrestling coach. He also sponsors National Honor Society. And he is also a director of after school sports academy. I am lucky to have him here as a teacher."

    Scott was recognized as an outstanding educator last year by the Montgomery County Council. He was also honored as 2011 teacher of the year by an African-American civil rights organization.

    Jake Scott says he wants mathematics to be something that students look forward to learning. And he says the results will help them on a path to college and a career.
