Syntax City – Where Grammar Comes to Life Welcome to Syntax City! As the mayor of this great city, I must warn you — we take our syntax very seriously here. When Syntax City was founded, our mission was to create a place where verbs agree with their subjects, tenses are always correct, and pronouns live in perfect harmony. Now, you and your students are invited to explore the city — where learning grammar becomes an adventure! Syntax City is an interactive, evidence-based app designed by speech-language pathologist Barbara Fernandes, M.S., CCC-SLP. Created for children in elementary and middle school, the app teaches English grammar and syntax through themed locations, animations, and play-based learning — perfect for speech therapy or classroom use. Explore 8 Grammar-Focused Locations Each area of the city targets a specific grammatical goal, with 415 questions across multiple levels of difficulty: • Gym: Do / Does (3 levels, 50 questions) • Beach: Third Person Singular (1 level, 50 questions) • Bakery: Was / Were (3 levels, 52 questions) • Ski Resort: He / She (2 levels, 50 questions) • Farm: Irregular Past Tense (2 levels, 59 questions) • Grocery Store: Has / Have (1 level, 51 questions) • Park: Is / Are (1 level, 50 questions) • Zoo: Regular and Irregular Plurals (3 levels, 54 questions) Each phrase is professionally narrated and paired with high-quality visuals that support comprehension and engagement. Engaging, Evidence-Based Learning • Multiple levels of difficulty adapt to each student’s learning pace • Visual cues reinforce comprehension and grammar recognition • Record and playback feature helps children hear and self-correct syntax • Positive reinforcement with animations, coins, and treasures • 127 collectible rewards across all locations motivate consistent practice After 10 gold coins, students unlock a treasure — each themed to the location they’re practicing. All earned treasures are stored in the player’s personal trophy case, which can be shared via email or printed. Built for Therapy and Classrooms Syntax City supports 1–5 players per session, allowing flexibility for individual or group practice. Students can work on one or multiple grammar targets at a time — creating nearly endless session combinations. Use two-finger zoom gestures to navigate the city map and assign players to specific locations. Each player’s goals, scores, and rewards are tracked individually. Powerful Data Tracking Just like all Smarty Ears apps, Syntax City offers detailed progress tracking: • Tracks accuracy, goals, and performance for each student • Provides color-coded graphs for visual progress review • Displays session summaries and goal mastery trends
