Flocabulary is a Brooklyn-based company that creates educational hip hop songs, videos and additional materials for students in grades K-12. 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. Flocabulary's website features videos, lesson plans, activities and assessments.
The company has emphasized outreach to underprivileged schools in its business decisions. As of 2015, more than 35,000 schools use Flocabulary products in the classroom. Flocabulary has been praised by rapper Snoop Dogg (AKA Snoop Lion) and historian Howard Zinn, and the company's products have been generally well received by educators and the press. However, the project has been criticized for perceived cultural inauthenticity and politically charged material in some song lyrics.
