Consonant digraphs are pairs of consonant letters that work together to make one new sound. Early readers meet them in common words like ship, chip, thin, and whale. Learning digraphs helps students read words more smoothly because they stop trying to sound out each letter separately.

The big idea is simple: two letters can make one sound.

Understanding Early Learners: Consonant Digraphs

A useful way to learn these letter pairs is to listen before looking at the spelling. Say a word slowly, then notice where the mouth changes position. For the sound in shop, the lips round slightly and air moves through a narrow space.

For the sound in chop, the mouth begins closed, then opens with a small burst of air. This careful listening helps children connect a spoken sound to the letters they see. It is more reliable than memorising a list of words.

Sound boxes can make the pattern clear. A teacher may say brush and ask a child to tap one box for each sound. The word has four sounds, b, r, u, and sh, even though it has five letters.

The final pair belongs in one box because it acts as one sound unit. This matters when children stretch out words for spelling. If they put each letter into its own box, they may become confused about why a word seems to have more letters than sounds.

The letters th need extra attention because they can represent two different speech sounds. In thin, the tongue touches lightly between the teeth and air continues out. In this, the tongue position is similar, but the voice is switched on and makes a buzzing sound.

Children can feel the difference by placing fingers gently on their throat while saying both words. The sound in this creates a vibration. The sound in thin does not.

At first, students do not need technical names for these sounds. They need many chances to hear, say, read, and sort words that use each one.

Some spelling patterns do not behave the same way in every word. The letters ch often have their usual sound in chair, lunch, and much, but they can sound different in a few words learned later, such as school or chef. The letters wh usually help make the w sound in words such as when and whisk.

Some speakers give the h a faint breathy sound, while others do not. These differences are normal. Beginning readers should first learn the common patterns, then notice exceptions as new books introduce them.

Reading practice works best when the target pattern appears in short, meaningful text. A child might read a sentence, find every word with the pattern, underline the two letters, then reread the sentence smoothly. Word sorting is helpful too.

Put wish, much, bath, and wheel into groups by their shared sound. Pay close attention to the whole word, because digraphs may appear at the beginning, middle, or end.

Regular practice builds quick recognition. Over time, readers see these letter pairs as familiar chunks instead of stopping to work out every individual letter.

Key Facts

  • A consonant digraph is 2 consonant letters that make 1 sound.
  • s + h = /sh/, as in ship.
  • c + h = /ch/, as in chip.
  • t + h = /th/, as in thin.
  • w + h = /wh/, as in whale.
  • In a digraph, 2 letters → 1 sound.

Vocabulary

Consonant
A consonant is a letter sound made by blocking or partly blocking air, such as b, t, s, or m.
Digraph
A digraph is two letters that work together to make one sound.
Sound
A sound is what you hear when a letter or group of letters is spoken.
Blend
A blend is two or more consonants together where each letter sound can still be heard.
Word
A word is a group of letters that has meaning when we read or say it.

Common Mistakes to Avoid

  • Reading sh as /s/ then /h/ is wrong because sh works together to make one new /sh/ sound.
  • Calling every two consonants a digraph is wrong because some pairs are blends, where both sounds can still be heard, like st in stop.
  • Skipping the h in ch, th, sh, or wh is wrong because the h helps change the sound of the first letter.
  • Using the same sound for th in every word can be confusing because th can sound different in words like thin and this.

Practice Questions

  1. 1 Circle the digraph in each word and count how many digraphs there are: ship, chip, thin, whale.
  2. 2 Write 2 words that begin with sh, 2 words that begin with ch, and 1 word that begins with th. How many words did you write in all?
  3. 3 Explain why sh in ship is a digraph but st in stop is not a digraph.
