CVC words blending is the moment a child turns separate sounds into a word they can read. CVC means consonant, vowel, consonant: short words like cat, sun and pig. On this page your child meets a little sound train with three letter carriages and an engine. They tap each carriage to hear its sound, tap the engine to squeeze the sounds together, and then pick the picture the train made. It turns "sound it out" into something they can see, touch and hear.

What are CVC words? (CVC words kya hote hain)

A CVC word has three sounds: a consonant, a short vowel in the middle, and another consonant. C-a-t, d-o-g, b-u-s. They are usually the first words children read with phonics because every letter makes its plain, usual sound, with no silent letters or tricky spellings. In Hindi you might explain it as three sounds joined into one word, much like + + becoming कमल.

Blending is the skill of saying the sounds one after another and hearing them join into a word: /s/ /u/ /n/ becomes sun. It is the heart of reading with phonics. A child can know every letter sound and still not read until blending "clicks", and that click often takes a few weeks of short, playful practice.

How to use the sound train

There are two tabs. Every instruction is spoken, so your child does not need to read.

Sound train

  1. A train appears with three letter carriages, for example c | a | t, and an engine at the front.
  2. Your child taps each carriage. It lights up and says its sound as a short sound word, such as "kuh" for c, "ah" for a and "tuh" for t. Some sounds are stretched, like "sss", "mmm" and "fff".
  3. When all three carriages are lit, the voice says "Now tap the engine to blend the sounds".
  4. Your child taps the engine. The carriages squeeze together and the voice says the sounds quickly, one into the next.
  5. The voice asks "Which picture did the train make?" and your child chooses from two or three pictures. The right answer says the word in English and Hindi.

Pick a word

This tab shows a grid of all 30 words with small pictures. Tap any word to play the train for it. After blending, the picture and the word appear with a "Pick another" button. It is good for practising one word again, or for letting your child choose a favourite animal.

As in every game on this site, a mistaken tap is never called wrong: the game names the picture your child chose, then the right one glows, then Golu, our marble mascot, points to it. Finished rounds earn a marble in the Goli Jar. The अ+A button changes the order of Hindi and English, and grown-up settings set your child's age, calm sound, calm motion, captions, fewer choices and high contrast.

An honest note about the voice: it is a clear computer voice, and it can only approximate single sounds. Real letter sounds are short and pure: /t/, not "tuh". Please say the pure sounds yourself as your child taps, with no extra "uh" on the end. Pure sounds blend much more easily: "sss-uuu-nnn" runs straight into sun, but "suh-uh-nuh" does not.

The 30 CVC words in the game, by vowel

The full word list with pictures, Hindi and pronunciation is further down the page. Sorting the words by their middle vowel is a useful way to teach them, one vowel at a time.

Short vowelSoundCVC words in the game
a/a/ as in apple ("ah")cat, bat, van, fan, pan, rat, hat, map, bag, cap
e/e/ as in egg ("eh")hen, bed, net, pen, web, leg, ten
i/i/ as in insect ("ih")pig, six, bin
o/o/ as in orange ("aw")dog, box, fox, pot
u/u/ as in umbrella ("uh")sun, bus, cup, bug, hut, tub

Start with short a words, since there are the most of them. Then add one new vowel at a time. Our vowels for kids page helps if the short vowel sounds are still new.

How to teach blending at home in 5 minutes a day

Blending starts with the ear, before letters. If your child can blend sounds you say out loud, reading the letters comes much more easily.

Step 1: oral blending (no letters)

  • Robot talk: speak like a robot: "Bring me your s-o-ck." "Sit on the b-e-d." Your child works out the word and acts.
  • I spy, sound style: "I spy a c-u-p." Your child finds the cup.
  • Two-part first: if three sounds are too many, start with the first sound and the rest: "c ... at".

Step 2: blending with letters

  • Arm tapping: say one sound as you touch your shoulder, one at your elbow and one at your wrist, then slide your hand down the arm to say the whole word. It works just like the engine squeezing the carriages together.
  • Stretchy words: hold each sound until it touches the next: "mmmaaap". Words that start with a stretchy sound (s, m, f, n) are the easiest to blend, so try sun, map, fan, net early on.
  • Kitchen cards: write CVC words on small pieces of paper and hide them near the real thing: pan on the pan, cup on a cup, pot on a pot.

Step 3: segmenting (the other way round)

Segmenting is breaking a word into sounds, which is what spelling needs. Say "bus" and let your child tell you the three sounds while touching three fingers. Blending and segmenting grow together.

Keep the vowel in the middle clear and short. Many children say the right first and last sounds but guess the vowel. If your child reads cat as cot, just point to the middle carriage and say its sound together.

CVC words worksheet and sentence ideas

There is no PDF file on this site, but you can print this page through the browser; the vowel table above and the word list below make a simple CVC words chart. Easy home-made practice:

  • Picture and word match: draw five pictures (cat, sun, pig, bed, box) and write the words in a mixed-up column. Your child reads and draws lines.
  • Missing middle: write "c_t", "p_g", "s_n" and let your child fill the vowel.
  • Change one sound: cat becomes hat, hat becomes hut, hut becomes tub... wait, that changed two sounds! Let your child catch you when you break the rule; children love it.
  • CVC sentences: once words are easy, try "A fox in a box", "The hen is in the pen", "Six red bugs".

Many of these words also rhyme with each other (cat, hat, bat, rat), so the rhyming words game is a natural next step.

Keep it calm: tips for every child

Blending can take weeks to click, and that is normal. Praise effort: "You said all three sounds!" If your child is stuck, blend the first two sounds for them ("ca...") and let them add the last. If they get frustrated, go back to robot talk games with no letters, or simply tap carriages for fun. For children with speech delay, autism or attention differences, the steady train and repeated steps help; choose a favourite word in the Pick a word tab and repeat it as often as they like. Bilingual children often blend well because they already listen closely to sounds, and hearing the word in Hindi and English after each train gives them a bridge between home and school. If you are worried about your child's speech or hearing, talk to your paediatrician.

Keep screen time short, 5 to 10 minutes, and sit together so you can say the pure sounds. For toddlers under 2, books, songs and real objects are better than any phonics game. When your child is ready, revise phonics sounds for kids and read more three letter words for kids.

CVC Blending Train: questions parents ask

What is the full form of CVC words?
CVC stands for consonant, vowel, consonant. A CVC word has a consonant sound, a short vowel sound in the middle and another consonant sound, like cat, pen, pig, dog and sun.
How do I teach my child to blend sounds?
Start with oral blending, with no letters: say "c-a-t" like a robot and let your child say "cat". Then use letters, touching each one while saying pure sounds, and slide your finger underneath to say the word fast. Practise 5 minutes a day.
At what age should a child read CVC words?
Many children blend spoken sounds at 4 to 5 and read CVC words by sounding out at 5 to 6 (UKG, kindergarten). By class 1 most read them quickly. Some children take longer, and that is normal.
Why does my child know letter sounds but cannot blend?
Knowing sounds and joining them are separate skills. Often the child says "kuh-ah-tuh" with extra "uh" sounds, which do not join into cat. Model pure, short sounds, start with stretchy sounds like s, m and f, and practise oral blending.
Does the voice in the game say pure sounds?
It is a clear computer voice that approximates the sounds, for example "kuh" for c. Please say the pure sounds yourself as your child taps each carriage, without the extra "uh", because pure sounds blend more easily.
Which CVC words should I teach first?
Start with short a words such as cat, map, fan and van, especially ones that begin with a stretchy sound like s, m, f or n. Then add one vowel at a time: e (hen, pen), i (pig), o (dog, box), u (sun, bus).
Is there a CVC words worksheet or PDF?
There is no PDF, but you can print this page through your browser; the word list and vowel table print cleanly. The worksheet ideas on this page are easy to draw at home.
Is this CVC blending game free?
Yes. It is free, with no sign-up, no ads and no app download. It works in the browser on phones, tablets and computers, and marbles in the Goli Jar are saved on your device.
