Sound Sleuths

Step 2: Substitution Cue: "Now watch closely! Take away sound #1 (/s/) and replace it with /k/. Push the new chip in. Blend the new word: /k/ /t/ /ɒ/ /p/ doesn't make sense! Let's swap sound #2 (/t/) to /l/. Now blend: /k/ /l/ /ɒ/ /p/ → 'CLOP'!"

Step 3: Deletion Cue: "Say 'clop' without the /k/. What is left? → 'LOP'!"

Master Phoneme Progression Ladders

Ladder A (Initial & Final Focus) CCVC / CVCC

• 1. SLIP (/s/ /l/ /ɪ/ /p/) Base word
• 2. Change /p/ → /d/ → SLID Sub final
• 3. Change /l/ → /n/ → SNID Nonsense test
• 4. Delete /s/ → NID Delete initial
• 5. Add /k/ to end → NICK Add final

Ladder B (Medial & Blend Focus) CCVCC

• 1. CRUST (/k/ /r/ /ʌ/ /s/ /t/) 5 phonemes
• 2. Change /ʌ/ → /æ/ → CRASP Sub vowel
• 3. Change /k/ → /g/ → GRASP Sub initial
• 4. Delete /t/ → GRASS Delete blend
• 5. Add /p/ to start → (N/A) / BRASS Sub blend

4. Precision Error Correction Protocol: "Hear It, Tap It, Fix It"

Common Error 1: Adding "Uh"

Student says "buh-l-end" instead of /b/ /l/ /ɛ/ /n/ /d/.

Correction: "Scissors snap! Clip the sound short: /b/!"

Common Error 2: Missing Blend Sound

Student drops /l/ in "clamp" and says /k/ /æ/ /m/ /p/ (cap).

Correction: "Isolate box 2: say /k/... /l/. Feel tongue move!"

Common Error 3: Letter Guessing

Student names letter 'C' instead of making the sound /k/.

Correction: "Eyes closed! We are hearing sounds, not looking at letters."

DIFFERENTIATION, CENTERS & ASSESSMENT

Tiered Scaffolding • Observational Rubric • Extension

10–15 Minutes

Tiered Instructional Pathways

Tier 2 Support / High Scaffolding 2–3 Phonemes

• Limit words to 2–3 phonemes (VC and CVC only: at, sit, map, rug) before advancing to consonant blends.
• Use tactile felt squares or pop-its so students physically feel tactile resistance when popping each sound.
• Pre-teach continuous sounds (/m/, /s/) before stop sounds (/t/, /p/) so students can stretch sounds without breaks.

Multilingual Learner (MLL) Scaffolds Visual & Articulatory

• Provide handheld mirrors so students can inspect lip shape, tongue placement, and airflow for English sounds (e.g., /th/ vs /f/, /b/ vs /v/).
• Pair spoken words with contextual image icons so vocabulary comprehension reinforces the auditory task.

Advanced Sleuths / Extension 5–6 Phonemes & Inversion

• Introduce 5-to-6 phoneme words with complex triple blends (splat, spring, strand).
• Sound Inversion: Reverse sounds in words (e.g., say "pat" backward → "tap"; say "mood" backward → "doom").

Partner & Independent Centers

Center 1: Sound Switch Mystery Box

Partner A draws a secret picture card, says the word, and commands Partner B to change one sound. Partner B moves chips on their mission mat to identify the new secret word.

Center 2: Sound Detective Whisper Phone

Students use whisper phones to segment target words into their own ears, verifying clean stop sounds without added vowels before checking with their peer detective.
