"He can identify every sound separately but can't put them together to read!"
Classic problem. James could tell you /k/ /a/ /t/ were the sounds in "cat," but when asked to blend them, he'd say "kuh-ah-tuh" - not "cat."
"He's learned the sounds but not the skill of blending," I explained. "And after blending comes segmentation, then manipulation. These are three different neural processes, and most kids are only taught the first. Let me show you the complete toolkit."
The Three Powers
Blending: Pushing sounds together into words (/k/ /a/ /t/ → cat) Segmentation: Pulling words apart into sounds (cat → /k/ /a/ /t/) Manipulation: Changing sounds to make new words (cat → bat)
Three distinct skills. All necessary. Rarely all taught.
The Blending Breakdown
Why James says "kuh-ah-tuh":
He learned letter sounds with extra vowel (schwa): "buh" for /b/ "kuh" for /k/
These aren't pure phonemes. They're phonemes plus schwa.
The Pure Phoneme Practice
Teaching clean sounds:
/b/ not "buh" (lips pop open) /k/ not "kuh" (back of throat click) /t/ not "tuh" (tongue tap)
Continuous sounds easier: /mmmmm/ can be held /sssss/ can be extended
Stop sounds must be crisp.
The Progressive Blending
Start easy, build complexity:
1. Compound words: foot-ball → football
2. Syllables: ta-ble → table
3. Onset-rime: c-at → cat
4. CVC phonemes: /k/ /a/ /t/ → cat
5. CCVC phonemes: /s/ /t/ /o/ /p/ → stop
6. Multi-syllable phonemes: Complex blending
Don't jump to step 4. Build through progression.
The Robot Talk Technique
Making blending fun:
"I'm a robot. I speak in sounds: /m/ /o/ /m/. What word did I say?"
Kids love decoding robot speech. Engagement through play.
The Segmentation Symphony
Segmentation is the reverse:
"How many sounds in 'shop'?"
Child must:
1. Hold word in memory
2. Mentally separate sounds
3. Count them
4. Articulate each
Answer: 3 (/sh/ /o/ /p/) not 4 (s-h-o-p)
The Elkonin Boxes
Visual support for segmentation:
Draw boxes: □ □ □ Say "cat" Push token into box for each sound /k/ → □ /a/ → □ □ /t/ → □ □ □
Making auditory visual.
The Manipulation Magic
Highest level skill:
Substitution: Change /k/ in cat to /b/ → bat Deletion: Remove /s/ from stop → top Addition: Add /s/ to top → stop or tops Reversal: Reverse sounds in pat → tap
This is complex cognitive work.
The Spoonerism Fun
Playing with initial sound swaps:
"Teddy Bear" → "Beddy Tear" "Lunch box" → "Bunch lox"
Kids find this hilarious. Learning through laughter.
The Assessment Ladder
Test systematically:
Blending:
● Can blend syllables?
● Can blend onset-rime?
● Can blend phonemes?
Segmentation:
● Can count syllables?
● Can separate onset-rime?
● Can count phonemes?
Manipulation:
● Can substitute initial sounds?
● Can delete sounds?
● Can add sounds?
Find the breakdown point.
The Classroom Choreography
Daily practice, 5 minutes:
Monday: Blending robot words Tuesday: Segmentation with boxes Wednesday: Initial sound substitution Thursday: Sound deletion games Friday: Mix all three skills
Short, focused, systematic.
The Movement Method
Physical actions for each skill:
Blending: Arms apart → bring together Segmentation: Fist → fingers spread Manipulation: Hand twist motion
Kinesthetic learning supports auditory.
What You Can Do Tomorrow
Clean up your phonemes: No extra sounds added.
Start with compounds: Easier blending practice.
Use Elkonin boxes: Visual segmentation support.
Play manipulation games: "Change cat to bat to mat to sat"
Robot talk daily: Fun blending practice.
Celebrate all three: Not just knowing sounds but using them.
The James Journey
Week 1: Learned clean phonemes (no schwa) Week 2: Blended syllables successfully Week 3: Blended onset-rime patterns Week 4: Blended CVC phonemes Week 5: Segmented words accurately Week 6: Beginning manipulation games
From "kuh-ah-tuh" to reading "cat" fluently.
The Spelling Connection
Segmentation = Spelling foundation
Can segment "jump" into /j/ /u/ /m/ /p/? Can spell "jump" correctly.
Can't segment? Spelling is guessing.
The Reading Recipe
Successful reading needs:
● Sound knowledge (phonemes)
● Blending skill (combining)
● Segmentation skill (analyzing)
● Manipulation skill (flexibility)
Missing any ingredient? Recipe fails.
The Parent Partnership
Home practice:
Blending: "Dinner is /p/ /i/ /zz/ /a/" Segmentation: "How many sounds in 'bed'?" Manipulation: "Change 'Day' to 'may' to 'say'"
No worksheets. Just word play.
The Intervention Intensity
Can't blend after instruction?
● Slow down sounds
● Use continuous sounds first
● Add visual supports
● Practice with syllables first
Can't segment?
● Use blocks/tokens
● Emphasize each sound
● Start with 2-sound words
● Build systematically
Can't manipulate?
● More blending/segmentation first
● Use letter tiles
● Make it visual
● Simplify to initial sounds only
The Beautiful Building
These three skills build on each other:
Blending → "I can make words from sounds!" Segmentation → "I can find sounds in words!" Manipulation → "I can play with sounds!"
Together they create phonemic flexibility.
The Tomorrow Teaching
Tomorrow, don't just teach sounds.
Teach what to DO with sounds:
● Blend them together
● Pull them apart
● Change them around
Because knowing /k/ /a/ /t/ isn't reading.
Blending them into "cat" is reading. Segmenting "cat" into sounds is spelling. Changing "cat" to "bat" is word play.
All three create readers.
Not just sound knowers. Sound users. Sound players. Sound masters.
And that's the difference between knowing phonics and using phonics.
Between recognizing sounds and reading words.
Between phonemic awareness and phonemic mastery.
Three skills. Blending, segmentation, manipulation. The complete toolkit.
Teach all three. Practice all three. Celebrate all three.
And watch reading explode.
