1 Phase 1: Auditory Cueing & Phoneme Isolation (5 Minutes)
Tuning the Ear
Teacher Script: "Detectives, listen to our target case word: SHIP. Echo the word together." (Students: "SHIP")
Multisensory Gesture: Instruct students to make a "detective fist" and tap each individual sound against their tactile palm pad: /sh/ (thumb tap), /ĭ/ (index tap), /p/ (middle tap).
Key Observation: Verify students isolate the digraph /sh/ as ONE continuous acoustic breath, not two separate sounds.
2 Phase 2: Tactile Tile Placement & Elkonin Mapping (10 Minutes)
Tactile Anchoring
Direct Instruction: Students pull one textured felt tile from their tray into the first sound box on their Elkonin mat while vocalizing the phoneme.
Finger Sweep & Blend: Students press firmly down on each tile, feeling the textured surface, then slide their pointer finger along the tactile arrow underneath from left to right: "/sh/ ... /ĭ/ ... /p/ → SHIP!"
Kinesthetic Check: Count tiles: "How many sounds did your fingers feel?" (3 sounds). "Are there any silent letters or blended chunks?"

Instructional Routine (Cont.)
Phases 3 & 4: Orthographic Transfer & Forensics
Evidence Phase
3 Phase 3: Orthographic Grapheme Mapping & Heart Word Coding (8 Minutes)
Print Transfer
Tile-to-Letter Swap: Students push each textured tile upward out of the box and write the corresponding grapheme (letter/letters) in the Elkonin box beneath.
Digraph Rule Notice: Emphasize: "Two letters, but one sound box! The letters s and h share a single room because they team up to make /sh/."
Heart Word Detective Note: For words with irregular spellings (e.g., said), draw a red heart above the tricky part (ai) — "We learn this part by heart!"
4 Phase 4: Clue Sentence Reading & Micro-Dictation (7 Minutes)
Application
Connected Text: Students open their Case Journals to the "Evidence Case" and read target-rich decodable sentences aloud using finger-tracking.
Micro-Dictation: Dictate 2 fresh words containing the target sound (e.g., CHIN, TRAP). Students tap, map, and write in journal boxes without teacher modeling.
Multisensory Accommodations & Adaptations
Tactile Defensiveness
Substitute rough sandpaper tiles with smooth velvet or weighted silicone push-pop buttons for students with sensory sensitivities.
Visual Crowding (Dyslexia)
Use yellow highlighter tracking frames and maintain high-contrast spacing (white boxes on charcoal borders) to prevent phoneme reversals.
Speech Articulation
Provide personal mouth-mirrors so learners can visually confirm lip and tongue placement for unvoiced /th/ vs voiced /th/ and /sh/ vs /ch/.

STEP 1
Tune Your Detective Ear
Listen & Echo First
Say the mystery clue word out loud: " SHIP "

/sh/
Thumb Tap
Quiet breath sound
2
/ĭ/
Pointer Tap
Short vowel chin drop
3
/p/
Middle Tap
Quick lip pop
Detective Clue: Even though /sh/ has two letters, your ears hear exactly ONE sound!
STEP 2
Place Your Tactile Sound Tiles
Feel Each Phoneme
Push one textured tile into each sound room as you say the sound:
/sh/ Felt Tile
/ĭ/ Smooth Tile
/p/ Felt Tile
Slide Finger Across Arrow: "/sh/ ... /ĭ/ ... /p/ → SHIP!"
Press firmly on each tile! Tactile pressure locks sounds into your memory bank.
STEP 3
Map Letters to the Sounds
Orthographic Mapping
Push tiles up, then write the letters into each box:
