The Science of Sentence Building.

Sentence Ninja follows a natural language acquisition hierarchy, ensuring every learner builds a rock-solid foundation before moving to advanced linguistic missions.

GROUPS 1 & 2

Early Syntax

Sentence Ninja Early Levels
  • ✔ Group 1: Basic Phrases – Subject + Verb (e.g., "cat + jumps") and Adjective + Noun pairings.
  • ✔ Group 2: Simple Sentences – Introducing articles and present tense structures like "The leaf + falls".
GROUPS 3 & 4

Functional Interaction

Question and Negation Levels
  • ✔ Group 3: Question Formats – Master "Who/What/Where" prompts and "Is/Are" verbing structures (e.g., "Is the girl sleeping?").
  • ✔ Group 4: Negation – Essential practice with "Not" in present tense and copula structures (e.g., "He is not tall").
GROUPS 5 & 6

Linguistic Mastery

Sentence Ninja Advanced Levels
  • ✔ Group 5: Advanced Logic – Navigating passive voice, future tense, and complex adverbs (e.g., "The man gives the lady flowers").
  • ✔ Group 6: Complex Clauses – The pinnacle level mastering multi-clause sentences with prepositional phrases.

Complete Clinical Control

Professionals can toggle specific sentence types "On" or "Off" or manually adjust the starting level for each player. This allows for a truly individualized intervention path.

Syntax: The Architecture of Meaning.

Sentence structure is the vital bridge between a single word and a complete thought. Without mastery of word order, communication breaks down. Sentence Ninja provides the professional-grade scaffolding required to build these essential linguistic foundations.

Mastering "The Science of Order"

The app teaches that word order is not random—it dictates meaning. By dragging words into the correct sequence, students see the immediate impact of syntax in real-time.

Bridging Receptive & Expressive Gaps

Sentence Ninja integrates visual sentence building with verbal recording, forcing the brain to connect the visual structure with the spoken word.

Data-Driven Clinical Intervention

For SLPs and Educators, the "WHY" is in the tracking. Detailed reports show exactly where a student’s syntax is failing—allowing for precise, targeted intervention.

Equip Your Students for Success

Mastering Mastery through
Tactile Engagement.

Every sentence is a mission. Students don't just look at grammar; they build it by dragging word fragments across the "stepping stones" of syntax.

1

The Ninja Sentence Strip

Students drag color-coded word pieces onto the scroll at the bottom of the screen to complete the target sentence.

2

Immediate Correction

If a word is placed incorrectly, it snaps back to its origin, encouraging the student to analyze the sentence structure and try again.

3

The Shuriken Hint System

Struggling ninjas can tap the "Hint" shuriken to see the first word of the sentence, providing the perfect amount of support without giving away the answer.

Example: Building a multi-word sentence using real-life context photos.

The Path to Independent Mastery.

Sentence Ninja doesn't just teach grammar; it systematically fades support. By moving from simple color-matching to total linguistic independence, we ensure students truly internalize the architecture of language.

STAGE 1: VISUAL MATCHING
Full Color Scaffolding with Lines

Building Confidence

Double Scaffolding: Students are provided with colored word fragments and matching colored lines on the sentence scroll. This allows the learner to focus on success by simply matching colors to positions.

STAGE 2: FRAGMENT CUES
Colored words with no lines

Syntactic Reasoning

The colored target lines are removed. While the word fragments remain color-coded, students must now rely on their own reasoning to determine the correct order on the blank sentence strip.

STAGE 3: FULL INDEPENDENCE
No colors no lines

Linguistic Mastery

All visual cues are withdrawn. The student builds the sentence using only linguistic knowledge and the context of the photograph. This represents true functional mastery of English syntax.

Precise Scaffolding Control

The professional settings menu allows you to independently toggle "Color Coded Cue" and "Display Colored Lines". This flexibility enables clinicians to create the perfect "just-right" challenge for every student.

The Final Mission:
Vocal Mastery.

Language is meant to be spoken. Sentence Ninja ensures that students don't just learn word order on a screen—they practice the rhythmic and phonetic delivery of their creations.

🎙️

Integrated Voice Recording

Once a sentence is built correctly, the app prompts the student to "Record it for you!". This reinforces the neural pathways between sight and speech.

🎧

Auditory Self-Modeling

Students can listen back to their recordings, enabling self-correction and helping them recognize grammatical nuances in their own voice.

📱

Telehealth Ready

This feature is vital for remote sessions, allowing SLPs to clearly hear a student's production even over poor internet signals[cite: 114].

The Art of
Group Intervention.

Efficient caseload management requires tools that adapt to multiple students at once. Sentence Ninja allows you to run high-energy group sessions where every participant works on a custom-tailored mission.

01

Simultaneous Individualized Levels

One student can practice foundational Level 1 (Subj. + Verb) while another masters Level 7 (Verbing + Article Object) in the same session.

02

Dynamic Performance Memory

The app remembers exactly where each player left off. Level progression is automatically based on their last performance, or can be manually overridden via the "Modify" button.

03

Seamless Turn-Taking

The interface encourages social interaction and peer modeling as students take turns on the shared device, each with their own personalized ninja avatar.

Concrete Imagery for
Abstract Concepts.

Abstract grammar rules can be difficult for many learners to grasp. Sentence Ninja uses vibrant, real-life photography to provide an immediate situational context for every sentence built.

📸

Functional Generalization

By seeing "washing + the dog" or "growing + a plant" in a real photograph, students link syntax to the actions they see in their daily lives.

🧩

Situational Clues

The photography provides a natural scaffold. Students use visual evidence from the photo to determine the correct subject and action, making grammar an act of observation.

The Evidence Behind the Missions.

🧠 Hierarchical Scaffolding

Research in language acquisition emphasizes the importance of a structured hierarchy. Sentence Ninja follows this science by transitioning students from 2-word foundational phrases to complex, multi-clause sentences across 39 distinct levels.

👁️ Multisensory Visual Cueing

The app utilizes "faded scaffolding"—a proven clinical technique. By using color-coded word fragments and target lines, it reduces cognitive load, allowing the brain to focus on the "science of word order" before transitioning to independent production.

🗣️ Receptive-to-Expressive Bridge

Effective intervention requires a link between understanding structure and producing speech. The integrated recording feature forces the student to move from the visual construction of syntax to verbal expressive output.

The Clinical Loop

Step 1: Visual Modeling High-quality real-life photography provides immediate context.
Step 2: Syntactic Manipulation Dragging word fragments to solve the structural "puzzle".
Step 3: Verbal Reinforcement Recording the completed sentence for auditory self-modeling.
