Grammaropolis is where grammar lives! Hailed as a Schoolhouse Rock for the 21st Century, Grammaropolis uses the parts of speech as animated characters starring in books, songs, videos, and interactive games. Our innovative, classroom-proven approach blends character-based content with more traditional quiz-based assessment and is designed to address students' varied learning styles. Because the parts of speech are personified based on their roles in the sentence, the characterization provides students with a more effective way to visualize and internalize the roles of the parts of speech and to identify how a sentence is put together. Grammaropolis was created and refined in the ultimate proving grounds: the classroom. Our advisors include standards-compliant curriculum experts, elementary and middle school teachers and administrators, and publishing and entertainment industry professionals.
