Sounds-Write Initial Code: What Parents Need to Know
Sounds-Write splits reading into two halves: the Initial Code, taught across eleven units in Reception, and the Extended Code, which runs through Year 1 and Year 2. The Initial Code covers the sounds and, crucially, the word shapes: three sound words first, then words with consonants bunched together, then the first digraphs. If your school uses Sounds-Write it will talk in units and codes rather than phases, which is why most phonics advice you find online will not quite fit.
What makes Sounds-Write different
Most programmes start from letters and ask what sound each one makes. Sounds-Write starts from the sounds and asks how each one gets written. That inversion sounds like hair-splitting and changes quite a lot in practice.
The consequence you will notice first is the vocabulary. Your child will talk about sounds and spellings rather than letters and phonemes, and about a sound "having several spellings" rather than a letter "making several sounds". They may say that ay is a spelling of the sound /ai/, which is a slightly different mental model from the one most adults were taught.
The second consequence is that there is less to memorise as an exception. Because everything is framed as a spelling of a sound, words that other schemes file under "tricky" are usually just spellings the child has not met yet. That is a kinder framing for a five year old, and a more accurate one.
The third is that Sounds-Write leans hard on writing alongside reading, from the first unit. Children build words with letter tiles or magnetic letters and pull them apart again, not as an extra activity but as the same lesson viewed from the other end. Reading a word is turning spellings into sounds; spelling a word is turning sounds into spellings. Teaching both together is deliberate, and it is why your child may come home able to write words they still read hesitantly.
The Initial Code, unit by unit
Eleven units, usually across Reception. The first seven introduce sounds, and the last four introduce word shapes.
| Unit | What is new |
|---|---|
| Unit 1 | a, i, m, s, t, in three sound words |
| Unit 2 | n, o, p |
| Unit 3 | b, c, g, h |
| Unit 4 | d, e, f, v |
| Unit 5 | k, l, r, u |
| Unit 6 | j, w, z |
| Unit 7 | x, y, and the doubles ff, ll, ss, zz |
| Unit 8 | No new sounds. Words ending in two consonants, such as lamp |
| Unit 9 | No new sounds. Words starting with two consonants, such as stop |
| Unit 10 | No new sounds. Longer clusters, such as strap and crunch |
| Unit 11 | The digraphs sh, ch, th, ck, wh, ng, qu |
Units 8 to 10 are the ones worth flagging to a parent, because they teach no new sounds at all. Everything in them is about handling consonants bunched together: a child has known every sound in strap for weeks, but holding five of them in the right order is a separate skill.
This is the point where a child who was flying often seems to stall, and it catches parents out badly because nothing new is being introduced. Nothing has gone wrong. Every scheme has this moment; other programmes call it Phase 4.
What the Extended Code covers
Everything else, and it is much bigger: roughly forty nine units spread over Year 1 and Year 2.
The Extended Code is where a child learns that one sound can be written several ways, and that one spelling can say several sounds. The sound /ai/ turns up as ai in rain, ay in day and a-e in make. Meanwhile the letters ow say one thing in cow and another in snow.
That second direction is the harder one, and it introduces a genuinely new skill: try a spelling, notice whether it produced a real word, and try the other if it did not. Reading stops being decoding and becomes decoding plus checking. Children who found the Initial Code effortless quite often find this hard, which is normal rather than a warning sign.
If your child reads a word wrongly, pauses, and fixes it without being told, that is not a mistake. That is the Extended Code working.
The four things Sounds-Write keeps coming back to
The programme is built on a small number of ideas that get repeated all the way through, and knowing them helps you support it at home.
- A sound can be written in more than one way. The /ai/ sound has several spellings.
- A spelling can represent more than one sound. ea in head and in bead.
- A sound can be written with one, two, three or four letters. e, ee, igh, eigh.
- Blending, segmenting and phoneme manipulation are skills that need practising, not facts to be learned.
That last one is the one parents most often skip. Knowing sounds is storage; blending is the actual skill. A child who says "p-i-n" and then pauses and waits has not blended yet, and more flashcards will not fix it. Oral blending will, and it needs no book: "can you pass me the c-u-p", "time for your c-oa-t", said at breakfast and in the car.
What the reading books look like
Sounds-Write books are matched to the unit, so a child in Unit 3 gets a book built only from the sounds of Units 1 to 3. That is a small palette, and the early books are correspondingly short.
Two things follow. The first is that the book coming home is meant to be easy: your child will usually have worked on those sounds in school already, so reading it fluently is the intended outcome rather than a sign the level is too low. The second is that the constraint lifts fast. Unit 11 brings the digraphs, and the Extended Code opens things up considerably within a term or two.
What matters is that the matched book is not the only reading in the house. Your child decodes the short book; you read them something far harder at bedtime, full of words they could not begin to spell. The first builds the mechanics, the second builds the reason to bother, and a child who only ever gets the first is being taught that reading is work.
When your child stalls
Two moments account for most of the worry, and both are built into the programme rather than signs of a problem.
The pause at the end of a word. A child sounds out "p-i-n" and then stops, looks up, and waits for you to say it. They have segmented but not blended. The fix is oral blending, away from print, as often as you can fit it in.
Units 8 to 10. Consonant clusters undo children who were previously fluent, because holding five sounds in sequence is genuinely harder than holding three. Expect several weeks here. Pushing on to Unit 11 before clusters are comfortable tends to produce a child who guesses.
If either persists for more than a few weeks, mention it to the teacher and ask which specific sounds and structures are secure. That question gets you something you can practise; asking whether your child is behind gets you a label.
What to do at home
- Say sounds cleanly. "mmm", not "muh". The trailing uh breaks blending, because muh-a-tuh is not a word.
- Use their language. Say "which spelling is that?" rather than "what letter is that?". It costs you nothing and keeps school and home consistent.
- Wait five seconds before helping. Most children get there at four.
- Give the sounds, not the word. "s-t-o-p" hands them the win.
- Do not push past a wobble in Units 8 to 10. Consonant clusters take time and that is by design.
- Stop while they still want more.
Where Sounds-Write sits among the other schemes
It is one of the validated programmes, and it is structurally the furthest from the others. Little Wandle, Bug Club, Twinkl and Essential Letters and Sounds all share phase numbers; Read Write Inc uses Sets; Sounds-Write uses codes and units and does not map neatly onto any of them.
Roughly, the Initial Code covers the ground that phase-based schemes split across Phases 2 to 4, and the Extended Code corresponds to Phase 5 and beyond. Do not lean on that too hard when choosing books, though. A book labelled Phase 3 by a publisher can easily contain a spelling your child has not met, and the only reliable check is to open a middle page and ask whether every content word is workable from what they have been taught.
If you are not certain what your school uses, the tells are easy to spot, and it is worth two minutes because whether a book is decodable depends entirely on the answer.
The programme's own site is at sounds-write.co.uk, and your school will have a document showing which unit your child is working in.
Lindo Phonics is not connected to Sounds-Write and is not endorsed by them. We match the published progression so a story only uses sounds your child has already been taught.
Common questions
What is the Initial Code in Sounds-Write?
The first eleven units, usually taught across Reception. Units 1 to 7 introduce the single letter sounds and the doubles ff, ll, ss and zz. Units 8 to 10 cover consonant clusters, and Unit 11 introduces sh, ch, th, ck, wh, ng and qu.
What is the Extended Code?
The much larger second half, roughly forty nine units across Year 1 and Year 2. It covers the fact that one sound can be spelled several ways and one spelling can say several sounds.
Why do Units 8, 9 and 10 have no new sounds?
Because they teach word shapes rather than sounds. A child has known every sound in strap for weeks, but holding five of them in the right order is a separate skill that needs its own practice.
How is Sounds-Write different from other phonics schemes?
It starts from sounds and asks how each one is written, rather than starting from letters and asking what each says. Children talk about sounds and spellings rather than letters, and words other schemes call tricky are usually just spellings not yet taught.
Does Sounds-Write use phases?
No. It uses the Initial Code and Extended Code, divided into units. That is why phase-based advice found online does not map onto it cleanly, and why a Phase 3 labelled book may not be right for your child.
How does Sounds-Write map onto the phases?
Roughly, the Initial Code covers the ground that phase-based schemes spread across Phases 2 to 4, and the Extended Code corresponds to Phase 5 and beyond. Treat that as a guide rather than an equivalence.
What are the four key ideas in Sounds-Write?
A sound can be written more than one way; a spelling can represent more than one sound; a sound can be written with one to four letters; and blending, segmenting and manipulating sounds are skills that need practice rather than facts to learn.
Does Sounds-Write teach tricky words?
Not in the same way. Because everything is framed as a spelling of a sound, words other programmes file as exceptions are usually treated as spellings the child has not met yet, which is both kinder and more accurate.
My child knows all the sounds but cannot read. Why?
Knowing sounds is storage. Blending is the skill. A child who says p-i-n and then pauses and waits has not blended yet. Practise oral blending with no letters in sight, saying things like pass me the c-u-p.
How should I say the sounds at home?
Cleanly, with no uh on the end. The letter m says mmm, not muh. A child blending muh-a-tuh gets a non-word and concludes that blending does not work.
What does CVC mean?
Consonant, vowel, consonant, which is the shape of a three sound word like cat or pin. You may also see CVCC for words like lamp and CCVC for words like stop, which describe where the consonants bunch together.
Is Sounds-Write a validated programme?
Yes, it is one of the systematic synthetic phonics programmes English schools can choose from. What varies between validated programmes is the order and the vocabulary, not whether they teach the alphabetic code.
Can I get a decodable book at my child's Sounds-Write unit?
Yes. Lindo Phonics builds a personalised story using only the sounds taught up to the point your child has reached, with them as the main character. The first one is free and does not need a card.
