Reading › Hearing sounds › Segmenting and sound tapping

What is segmenting?

Segmenting is the opposite of blending: a child hears a word and pulls it apart into its sounds. Many classes tap a finger to the thumb for each sound, so cat gets three taps: /c/ /a/ /t/.

Grades K–1Common Core RF.K.2d · RF.1.2dAlso called: sound tapping, phoneme segmentation60-second read
cat/c/tap 1/a/tap 2/t/tap 3
  • Hear the word, then say it slowly.
  • Tap once per sound: pointer, middle, ring finger.
  • cat → /c/ /a/ /t/: three taps
Blending puts sounds together. Segmenting takes them apart.

Why schools teach it

It's the skill behind spelling

To spell a word, a child first has to hear every sound in it. Kindergartners pull apart short words (RF.K.2d), and first graders segment longer words, including ones with blends like /s/ /t/ /o/ /p/ (RF.1.2d).

Tapping gives each sound a physical place, so kids don't skip one. Some classes tap fingers to the thumb, others tap down the arm from shoulder to wrist. Either way, one tap means one sound.

What to say, and what to skip

Say this

  • Say it slowly and tap each sound.
  • How many sounds did you hear?
  • What's the first sound? The last?Start with the ends; the middle is hardest.
  • Now write a letter for each tap.Segmenting turns straight into spelling.

Skip this

  • Tapping once per letter.Ship has four letters but three taps: /sh/ /i/ /p/.
  • Spell it: S-H-I-P.Letter names skip the step of hearing sounds. Ask for sounds first.
  • Stretching the word for them every time.Let your child stretch it. That's the practice.

See it in action

Spelling “stop” by tapping

  1. Say the word and tap each sound

    /s/ /t/ /o/ /p/: 4 taps
  2. Check the start: two sounds, not one

    /s/ and /t/ get separate taps
  3. Write one spelling for each tap

    s-t-o-p → stop

Kids often hear only /s/ /o/ /p/. Tapping slowly catches the hidden /t/.

Parents also ask

What's the difference between segmenting and blending?

Blending joins sounds into a word, for reading. Segmenting splits a word into sounds, for spelling. Kids practice both.

Should we tap fingers or arms?

Whichever the class uses. Ask the teacher or your child.

My child adds extra sounds.

Often it's an “uh” after a sound, like /buh/. Practice the pure sounds, then tap again.

Can we do this without paper?

Yes. Say a word in the car and have your child tap and count the sounds.
