# Phonics Vocabulary

Know and use the vocabulary of phonics and word structure — phoneme, grapheme, GPC (grapheme-phoneme correspondence), blend, segment, digraph, CVC, vowel, consonant, syllable, root word, suffix, prefix, and homophone — and understand that these words describe the building blocks that phonics instruction is built on

## Ready when they can

- Say the sounds for common graphemes (e.g. 'sh', 'ch', 'th', 'ee', 'igh') and use 'phoneme' and 'grapheme' correctly when explaining
- Blend sounds together to read an unfamiliar word and explain what they are doing using the word 'blend'
- Segment a word into its individual sounds for spelling and use the term 'segment' to describe the process

## Lesson: Words phonics uses

Phonics has its own special words. These words help you talk about sounds and letters.

A phoneme is one sound, like the first sound in 'sun'. A grapheme is the letter or letters that show that sound.

*(drawing: Blend c, a, t together to make the word cat.)*

**Example.** Mia wants to spell 'sun'. She segments it into three sounds: s, u, n. Then she writes s, u, n as letters.

**Tip.** A digraph is two letters that make one sound. Say 'sh' in 'ship'. It makes one soft sound.

**Recap.** Phonics words like phoneme, blend, and segment describe sounds and letters.
