Hip hop, or rap music as it's also called, started on the streets and in the clubs of New York City in the 1970s, but today many countries have their own kind of hip hop music, This kind of music has its roots in reggae，disco and funk music. Rapping, which speaking to the rhythm of the music，is an important part of this music. Young people rap to express how they feel about their lives and problems.
Would you like to rap in class? Well actually, hip hop music is being played in more than 10,000 schools in the USA. Why? There is a new school programme called "Flocabulary" where teachers use text books and hip hop CDs to help teach a variety of school subjects.  The lyrics of the songs include information on a subject students are studying, which makes learning easy and fun  Students and teachers are amazed at the positive effects it has had on exam marks. This is one teacher said: "I've used hip hop songs in class, and I've never seen students have such interests in history!  It's unbelievable how students remember what I teach it even encourages us towrite our own songs.
Blake Harrison, a high school student, first thought of the idea of Flocabulary. The word "Flocabulary" comes from the words "flow" and "vocabulary". "Flow" is a rap word for "style" or the way a rapper says the words of a song. How did he get the idea'? Well he realized he could remember the lyrics of a hip hop song very easily.  So, why not make lessons into songs'? Today together with Alex Rappaport, a composer, Blake produces hip hop songs for maths .science and literature, which are now being used in schools with great success.
