FlocabularyHip hop or rap （ 說唱）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 10，000schools 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 and 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 （ 文學）．They are now used in schools with great success．
