Flocabulary is a Brooklyn-based company that creates educational hip hop songs, videos and additional materials for students in grades K-12.

[1] Founded in 2004 by Blake Harrison and Alex Rappaport, the company takes a nontraditional approach to teaching vocabulary, United States history, math, science and other subjects by integrating content into recorded raps.

[12] After participating in a collaborative business advice program with Columbia students, Harrison and Rappaport decided to stop self-publishing and returned to Cider Mill.

[12] Flocabulary's 2007 release Shakespeare Is Hip-Hop featured musical and lyrical contributions from a number of hip hop artists, including Grammy Award-winner 9th Wonder.

[4] Rappaport says that Flocabulary has made access to its products a priority over profitability, saying, "We wanted to reach the kids who might never get to the SATs, whose families weren't buying books at Barnes & Noble.

[20][21] School Library Journal notes that, "[Flocabulary's] catchy songs hook K-12 students in a way that textbooks can't.

"[22] A reporter for The Wall Street Journal visited classrooms where Flocabulary was being used and remarked that, "When third-grade teachers asked questions about the videos and vocabulary, the problem wasn’t getting children to raise their hands, but to put them down.

"[24] BuzzFeed called a series of Flocabulary videos created for Black History Month, "the coolest way to teach.

"[5] Jack Rosenthal of The New York Times says that Flocabulary is "one example of how Web sites have latched onto mnemonics as ways to teach SAT words to high-school students.

"[28] In November 2014, Entrepreneur.com reporter Laura Entis called a video about credit cards in Flocabulary's financial literacy series “direct, clear and insanely catchy.”[29] Common Sense Media notes that, "One of Flocabulary's best qualities is that the songs sound like real rap songs, not an embarrassing facsimile that's obviously for educational purposes.

The backing beats and samples are catchy and memorable, and videos contain a fun combo of stock footage, original animation, and, for The Week in Rap, current news clips.
