Hip hop or rap (说唱） music as it is also called, started on the street and in the clubs of the New York City in the 1970s . But today many countries have their own kind of  hip hop music . This kind of music comes from reggae, disco and funk music . Rapping means speaking to the  rhythm of the music, and it is an important part of the music . People rap to express how they feel about their lives and problems .

Rapping in class.

Would you like to rap in class? Well actually, hip pop music is played in more than 10,000 schools in the USA .Why ? There is a new school program called “ Flocabulary ”in which teachers use texts and hip hop CDs to help teach different school subjects . The words of the songs are just what students are studying . This makes learning easy and fun . Students and teachers are excited about the positive results it has had on exam marks . One teacher said, “ I’ve used hip hop songs in class, and I have never seen my students so crazy about history ! You can't imagine how well they imagine how well they remember what I teach ! We even try to write our own songs . ”

Whose idea was Flocabulary?

Blake Harrison, a high school student, was the first person to come up with the idea of Flocabulary . The word “ Flocabulary ” comes from the word “ flow ” and “ vocabulary ” . “ Flow ” is a rap word for “ style ”,or the way a rapper says the words of a song . “ Vocabulary ” means the words you have to learn in a language . How did he get the idea ? Well, he realized he could remember the words of a hip hop song very easily . So,why not make lessons into songs ? Today together with Alex Rappaport, a song writer, Blake produces hip hop songs for maths, science and literature (文学）. They are now used in schools with great success .
