Hip hop or rap music started on the street and in the clubs of the New York City in the1970s.People rap to express how they feel about their lives and problems.
   Nowadays，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，such as physics，math and so on.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 my lesson!You can't imagine how well they remember what I teach!We even try to write our own songs."
   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，as he listened to hip hop song first time，he sensed a strong joy.And he could remember the words of a hip hop song very easily. "So，why not make lessons into songs？" he thought.Today，together with Alex Rappaport，a song writer，Blake produces hip hop songs for maths，science and English.They are now used in schools with great success.
