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

This app was developed by an ASHA certified speech-language pathologist to promote understanding and use of early developing semantic categories and vocabulary. It is appropriate for children who are developing language normally and those who are language delayed. This app focusses on 28 “superordinate” categories, including: appliances, body parts, buildings, cleaning supplies, clothing, colors, desserts, dinosaurs, drinks, farm animals, fruits, furniture, insects, jungle animals, kitchen utensils, letters, make-believe, musical instruments, ocean animals, numbers, people, shapes, school supplies, sports equipment, tools, toys, transportation and vegetables. Each superordinate category contains 8 subordinate members which are each represented by a visually appealing illustrated image. There are 5 activities to choose from, including: SORTING In this activity, the user chooses from 1 to 3 semantic categories on which to focus. Pictured subordinate members are scattered at the top of the screen. The user is directed to drag the pictured items to their appropriate category container. FIND IT! In the “Find It!” game, the user chooses one pictured item from an array of three that belongs to a specifically named semantic category. The game consists of ten trials. A percentage correct score is presented at game’s end. Anywhere from 2 to 5 semantic categories can be targeted in this game. WHICH DOES NOT BELONG? In this game, the user is presented with 2 pictured items from the same superordinate category and one pictured item from a different superordinate category. The user is directed to find the item that does not belong with the other two. The game consists of ten trials. A percentage correct score is presented at game’s end. Anywhere from 2 to 5 semantic categories can be targeted in this game. MEMORY MATCH In this mode the user can choose a category and play an entertaining visual memory game with the associated pictured category members. This lends a fun twist to vocabulary practice. FLASHCARDS Use the flashcard mode to introduce or practice naming of category members. Within each category there are 8 vocabulary words.

ReceptionRating · Positive reviews · Number of ratings

28 Categories For Kids holds the better App Store score, 4.9 against 3.5. That said, the two scores are not equally well evidenced: 28 Categories For Kids has 120 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 73% of Syntax City's written reviews are positive against 67% of 28 Categories For Kids's, so the app with the better star average is not the one people write more warmly about.

Syntax City ships an update every 11 months, 28 Categories For Kids every 4 months. Both last shipped on September 9, 2026.
