CVC Words Worksheets

Kindergarten-1st gradePhonicsFree PDF + answer key

CVC words like “cat,” “pig,” and “sun” follow a simple consonant-vowel-consonant pattern that's usually the first blending skill taught after letter sounds. This missing-letter worksheet has kindergarten and first-grade students fill in the vowel or consonant that completes each short word, reinforcing sound-by-sound blending.

How to teach blending consonant-vowel-consonant words

  1. 1

    Say each sound separately first

    Have your child say each letter sound in the word out loud — /c/ /a/ /t/ — before blending them together into the full word.

  2. 2

    Blend slowly, then speed up

    Practice stretching the sounds together slowly at first, then repeat the same word at a normal speaking pace.

  3. 3

    Fill in the missing letter by sound

    Ask your child which sound is missing from the word before they write the letter, rather than guessing visually.

  4. 4

    Read the completed word aloud

    Once the missing letter is filled in, have your child read the finished word aloud to confirm it makes sense.

Common mistakes kids make

  • Guessing the missing letter without sounding it out — always say the whole word slowly first to identify the missing sound.
  • Mixing up short vowel sounds — review the five short vowel sounds with a quick chant before starting the worksheet.
  • Rushing past blending practice — slow, stretched-out blending builds a stronger foundation than fast guessing.
  • Only working on one vowel family — rotate between short a, i, and o words so no single sound is over-practiced.

Tips for parents and teachers

  • Use small objects like blocks to represent each sound, then push them together as your child blends the word.
  • Keep a whiteboard nearby to quickly test new CVC words beyond what's printed on the worksheet.
  • Celebrate blending progress with a sticker chart, since this is often a breakthrough skill for early readers.

Frequently asked questions

What does CVC stand for?

CVC stands for consonant-vowel-consonant, describing the pattern in simple three-letter words like “bed,” “hop,” and “run.”

When do kids typically learn CVC words?

Most children begin blending CVC words in kindergarten after they've learned individual letter sounds.

Why are CVC words taught before sight words?

CVC words follow predictable phonics rules, making them a natural first step for teaching blending before moving to irregularly spelled sight words.

What if my child can say each sound but can't blend them?

Practice blending just two sounds at a time first, then add the third sound once the two-sound blend feels automatic.

Are there worksheets for specific vowel sounds?

Yes, this site also has dedicated short a, short i, and short o worksheets for focused single-vowel practice.
