CH Words for Kids

CH words are words containing the digraph CH, where the letters C and H combine to make one sound /ch/, as in chat, chip, and chop. Unlike blends where each letter keeps its sound, digraphs create a new sound. CH is typically the first digraph taught in the Science of Reading sequence. LUCA's SoundScout detects the /ch/ phoneme precisely.

How to Read CH Digraph Words

1

Sound it out.

Point to each letter and say its sound separately. Then blend the sounds together smoothly without pausing between them. Slide the sounds together until the word emerges naturally.

2

Use it in a sentence.

Practice 5 to 10 words per session. Have your child read each word aloud, then say a sentence using that word. This builds decoding accuracy and vocabulary together.

3

Read it in a story.

When your child reads the word list fluently, move to connected text. Decodable stories from StoryGen feature ch digraph words in context, bridging word reading and real fluency.

Grade Level and Sequence

CH Digraph words are part of digraphs in the Science of Reading phonics sequence.

Prerequisite skills: Letter recognition, phonemic awareness (hearing individual sounds in spoken words).

What comes next: After mastering this pattern, children progress to related patterns, then advance to the next category. LUCA's Pathfinder sequences this automatically.

Grounded in Reading Science

These word lists follow the phonics scope and sequence recommended by the National Reading Panel. Systematic, explicit phonics instruction produces the strongest reading gains across all demographics and learning profiles.

LUCA's approach builds on orthographic mapping research by Ehri (2014), demonstrating that readers store words by connecting spellings to pronunciations at the phoneme level. This is exactly what SoundScout measures.

SH Digraph Words

SH words are words containing the digraph SH, where the letters S and H combine to make one sound /sh/, as in ship, shop, and shell. SH can appear at the beginning or end of words (ship, fish). This digraph is introduced in first grade after consonant blends. LUCA's SoundScout identifies whether the /sh/ phoneme is produced correctly in all positions.

TH Digraph Words

TH words are words containing the digraph TH, which produces two different sounds: voiced /th/ as in this and that, and unvoiced /th/ as in thin and thick. TH is one of the trickiest digraphs because of this dual nature. LUCA's SoundScout distinguishes between voiced and unvoiced TH at the phoneme level, targeting the specific variant a child struggles with.

Frequently Asked Questions

CH digraph words contain the two-letter combination CH, which together makes the single sound /ch/ as heard at the start of 'chat' and 'chest.' Unlike a blend, neither C nor H keeps its individual sound in the CH digraph.

Introduce CH as a unit. Show children that C and H together make a new sound /ch/ and practice identifying CH words by sound before by sight. Word sorts comparing CH words with SH words help children distinguish these two common digraphs.

No. CH makes /ch/ in most English words (chat, child) but makes /k/ in words borrowed from Greek (school, chorus) and /sh/ in words from French (chef, machine). Systematic instruction teaches the main pronunciation first, then exceptions are introduced in later grades.
