Letters and Sounds Phases Explained — From Phase 1 to Phase 5

If your child is in Nursery, Reception, or Key Stage 1, you've probably heard the term "Letters and Sounds." It's the phonics programme that most UK schools use to teach reading — and it's divided into phases.

Understanding these phases helps you make sense of what your child is learning at school and how you can support them at home. Here's everything you need to know, explained without the jargon.

What is Letters and Sounds?

Letters and Sounds is a systematic phonics programme published by the Department for Education. It teaches children the relationship between letters (graphemes) and sounds (phonemes) — which is the foundation of reading and spelling in English.

The programme is divided into six phases, taught from Nursery through to Year 2. Some schools use Letters and Sounds directly; others use programmes based on it (like Jolly Phonics, Read Write Inc, or Little Wandle). The phases and progression are broadly similar across all of them.

Phase 1: Tuning into sounds

When: Nursery (ages 3–4) Focus: Listening skills, not letters

Phase 1 isn't about reading at all. It's about developing your child's ability to hear and distinguish sounds. Activities include:

• Listening to environmental sounds (traffic, birdsong, rain)
• Playing rhythm and rhyme games
• Clapping syllables in words (ba-na-na = three claps)
• Identifying the first sound in a word ("What does 'dog' start with?")

This phase lays the groundwork. A child who can hear individual sounds in words is ready to start matching those sounds to letters.

At home: Play "I spy" using sounds, not letter names ("I spy something beginning with 'sss'"). Sing nursery rhymes. Read books with lots of rhyme and repetition.

Phase 2: Learning the first sounds

When: Early Reception (ages 4–5) Focus: 19 letters and their sounds

In Phase 2, children learn their first letter-sound correspondences. These are taught in a specific order, designed so that children can start blending words as quickly as possible.

The sounds are introduced in sets:

• Set 1: s, a, t, p
• Set 2: i, n, m, d
• Set 3: g, o, c, k
• Set 4: ck, e, u, r
• Set 5: h, b, f, ff, l, ll, ss

By the end of Set 1, children can already blend simple words like "sat," "tap," and "pat." This is intentional — early success builds motivation.

Children also learn to segment words (break them into individual sounds) for spelling: "cat" = c-a-t.

At home: When your child brings home reading books, let them sound out words at their own pace. Practise the sounds (not letter names) — "sss" not "ess." Keep sessions short: five minutes is plenty.

Phase 3: Completing the alphabet and digraphs

When: Reception (ages 4–5) Focus: Remaining letters plus digraphs and trigraphs

Phase 3 completes the alphabet and introduces sounds that are represented by two or three letters together:

• Remaining letters: j, v, w, x, y, z, zz, qu
• Consonant digraphs: ch, sh, th, ng
• Vowel digraphs and trigraphs: ai, ee, igh, oa, oo (two sounds: "moon" and "book"), ar, or, ur, ow, oi, ear, air, ure

A digraph is two letters making one sound (sh, ch). A trigraph is three letters making one sound (igh, ear). Children learn to recognise these as single units of sound, not individual letters.

By the end of Phase 3, children can read simple sentences and captions. They can also spell words containing the sounds they've learned.

At home: Point out digraphs in everyday life — "sh" on the shop sign, "ch" on the chocolate wrapper. When reading together, help your child spot digraphs rather than sounding out each letter separately.

Phase 4: Blending and segmenting with clusters

When: Late Reception (ages 4–5) Focus: Consonant clusters (no new sounds)

Phase 4 introduces no new sounds. Instead, it focuses on reading and spelling words with adjacent consonants — sometimes called consonant clusters or blends:

• Words like trip, clap, stamp, blend
• Words with clusters at the end: best, help, jump

This is where some children find things harder. Blending "s-t-r-ee-t" requires holding more sounds in memory than "c-a-t." Practice and patience are key.

Children also read and write short sentences, including tricky words that can't be fully sounded out (like "said," "the," "was").

At home: Play blending games in the car: "Can you blend these sounds: ch-i-p? What's the word?" Gradually use longer words with clusters.

Phase 5: Alternative spellings and pronunciations

When: Year 1 (ages 5–6) Focus: New graphemes and alternative pronunciations

Phase 5 is a big jump. Children learn that the same sound can be spelled in different ways, and the same spelling can represent different sounds.

For example:

• The "ay" sound can be spelled: ai (rain), ay (play), a-e (cake), ey (grey), ea (great)
• The letter "a" can sound like: a (cat), ay (apron), ar (father), o (was)

New graphemes introduced include: ay, ou, ie, ea, oy, ir, ue, aw, wh, ph, ew, oe, au, a-e, e-e, i-e, o-e, u-e

This phase runs throughout Year 1 and is the most content-heavy. It's also when children sit the Phonics Screening Check (in June of Year 1).

At home: This is where phonics practice at home makes the biggest difference. Regular, short practice sessions help children remember the many spelling alternatives. Spark Learn covers all phases from Phase 2 to Phase 5, with flashcards that use spaced repetition to help sounds stick.

Phase 6: Fluency and spelling rules

When: Year 2 (ages 6–7) Focus: Spelling patterns, suffixes, and fluency

Phase 6 shifts focus from decoding individual words to reading fluently and understanding spelling rules:

• Adding suffixes: -ing, -ed, -er, -est, -ful, -ly, -ment, -ness
• Spelling rules: doubling consonants, dropping the 'e', changing 'y' to 'i'
• Past tense spellings: jumped, running, hopped
• Recognising and spelling common exception words

By the end of Phase 6, children should be reading fluently and independently, using phonics knowledge as one of several strategies for tackling unfamiliar words.

How the phases fit together

Here's a simplified timeline:

| Phase | Year group | Key learning | |-------|-----------|-------------| | Phase 1 | Nursery | Listening to sounds | | Phase 2 | Early Reception | First 19 letter sounds | | Phase 3 | Reception | All letters, digraphs, trigraphs | | Phase 4 | Late Reception | Consonant clusters | | Phase 5 | Year 1 | Alternative spellings | | Phase 6 | Year 2 | Fluency and spelling rules |

Every school moves at a slightly different pace, and every child progresses differently. Some children sail through; others need more time on certain phases. Both are completely normal.

Common parent questions

"My child is in Year 1 and still on Phase 3. Should I worry?"

Not necessarily. Some children need longer to consolidate earlier phases, and that's fine. If your child's teacher hasn't raised concerns, they're likely progressing at an appropriate pace. If you're worried, ask the teacher — they'll be happy to explain where your child is and what support is in place.

"Should I teach letter names or letter sounds?"

Sounds first, always. When your child is learning to read, they need to know that the letter 's' says "sss," not "ess." Letter names become useful later, but sounds are the priority in Reception and Year 1.

"My child can read but can't spell. Is that normal?"

Very normal. Reading (decoding) is usually ahead of spelling (encoding). A child might read the word "night" but spell it "nit." This is because reading requires recognition, while spelling requires recall — a harder skill. Spelling catches up with practice.

How to help at home

The best thing you can do is:

1. Practise sounds regularly — even five minutes a day makes a difference
2. Read together daily — both listening to your child read and reading to them
3. Keep it positive — phonics should never feel like a punishment
4. Follow the school's lead — ask which phase your child is on and focus on those sounds

Phonics is a journey, not a race. Every sound your child masters is a building block towards confident, independent reading. And that's worth celebrating.
