"The linguistic insights are pure gold." - Wired "Learning grammar has never been more fun!" - School Library Journal "Bright, cheerful, and very entertaining" - Tech & Learning **Multiple Features in the Education App Store: What's Hot, New & Noteworthy, and Apps for Elementary School** (FOR SCHOOLS WITH VPP: PLEASE USE "GRAMMAROPOLIS - COMPLETE EDITION") Grammaropolis is where grammar lives! Hailed as a Schoolhouse Rock for the 21st Century, Grammaropolis uses the parts of speech as animated characters whose personalities are based on the roles they play in the sentence. From the shady pronoun always trying to take the noun’s place to the motherly conjunction who just wants everyone to get along, Grammaropolis achieves the seemingly impossible: we make learning grammar fun! Your free download includes access to the Noun neighborhood. Let Nelson the noun lead you with a curriculum map that includes a song, a book, videos, and over 400 quiz questions. Follow the map to earn your badge! Upgrade with In-App Purchases at any time for access to the other seven parts of speech: -Verbs -Adjectives -Adverbs -Pronouns -Conjunctions -Prepositions -Interjections Our innovative, classroom-proven approach blends character-based content with 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. - Winner of The National Parenting Center’s 2012 Seal of Approval - Winner of a 2012 Parents' Choice Approved Award - Winner of a 2012 NAPPA Silver Award - Top Ten Hit on Sirius XM Kids’ Place Live (“Welcome to Grammaropolis”)
