Writing - Transcription (Spelling)

KS1

EN-KS1-D004

Phoneme-grapheme correspondences, spelling patterns and exception words

National Curriculum context

Writing — transcription: spelling at KS1 involves teaching children the spelling patterns and rules that build on their phonic knowledge to encode words in writing. Pupils learn to spell common exception words (those that do not follow regular phonics patterns), the days of the week, and an increasing range of words with common suffixes and prefixes. The statutory curriculum requires pupils to apply the rules of adding common suffixes (-s, -es, -ing, -ed, -er, -est), to use apostrophes correctly for contractions, and to distinguish between homophones and near-homophones. Developing accurate spelling frees children's attention for the compositional aspects of writing, which is why transcription skills — spelling and handwriting — are given explicit statutory attention separate from composition.

Apply phonics knowledge to spell words

introduction Curated

Spelling using phonemes is the primary productive spelling strategy; learning exception word spellings is the complementary memorisation strategy for words the phonics route cannot reach — taught in parallel from the start.

2 concepts Patterns
2

Understand and apply prefixes, suffixes and root words

practice Curated

Suffixes, prefixes and root words form a mutually defining morphological trio; C029 explicitly lists C027 and C028 in its co_teach_hints, and all three are required to understand word formation.

Spell plurals, homophones and words with regular patterns

practice Curated

Plural formation, homophones and spelling patterns are the three pattern-application challenges at KS1 — plural rules interact with suffix rules, and homophones highlight the difference between sound and spelling; C030 co_teach_hints link to all three.

4

Use apostrophes for contractions and singular possession

practice Curated

Contractions and possessive apostrophes (singular) are the two KS1 apostrophe functions; C032 lists C031 in its co_teach_hints and both are most effectively taught together by contrast.

Spelling using phonemes

Keystone skill AI Direct

EN-KS1-C025

Hearing sounds in words and choosing appropriate graphemes

Teaching guidance

Teach spelling through phoneme segmentation — children say the word, identify each phoneme, and write the corresponding grapheme. Use phoneme frames and say-the-sounds mats. Begin with CVC words and progress to words with digraphs, adjacent consonants and longer structures. Encourage 'have a go' spelling using phonic knowledge rather than asking an adult for every word. Practise regular dictation of words and sentences using GPCs that have been taught.

Vocabulary: spell, sound out, segment, phoneme, grapheme, write, say the sounds, have a go
Common misconceptions

Children may represent only the most prominent sounds in a word, omitting unstressed vowels or consonants in clusters (e.g., writing 'grl' for 'girl'). They may use letter names rather than phonemes when segmenting. Some children use a plausible but incorrect grapheme for a phoneme (e.g., 'rane' for 'rain') — this shows good phonic application and should be praised before teaching the correct spelling.

Difficulty levels

Entry

Writing the correct grapheme for each phoneme in simple CVC words using phoneme frames.

Example task

Say the word 'pen'. Write one letter in each box for each sound you hear.

Model response: Child writes p-e-n in three boxes.

Developing

Spelling words with digraphs and adjacent consonants by segmenting and selecting appropriate graphemes.

Example task

Spell the word 'black'. Say each sound first, then write the letters.

Model response: Child says /b/ /l/ /a/ /ck/ and writes 'black'.

Expected

Spelling age-appropriate words accurately by applying phonic knowledge, choosing correctly between alternative graphemes.

Example task

Write this sentence from dictation: 'The train went through the dark tunnel.'

Model response: Child writes the sentence with 'train' (ai), 'through' (exception), 'dark', 'tunnel' spelled correctly.

Greater Depth

Spelling words with less common grapheme choices and explaining why a particular grapheme is used.

Example task

Spell the word 'weight'. Which grapheme did you use for the /ay/ sound? Why not 'ai' or 'a-e'?

Model response: Writes 'weight'. 'I used "eigh" for the /ay/ sound. It's not "ai" or "a-e" — "eigh" is a less common way to spell it. You just have to learn which words use "eigh".'

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Access barriers (2)
high
Auditory Processing Reliance

Spelling using phonemes requires the child to hear the sounds in a word they want to write and select appropriate graphemes. If auditory processing is impaired, the child cannot accurately segment the word into sounds to spell.

high
Working Memory Load

Phonemic spelling requires holding the whole word in memory, segmenting it into phonemes, selecting graphemes for each phoneme, and writing them in sequence — all while maintaining the motor programme for handwriting. This is a very high simultaneous working memory load.

Learning exception word spellings

knowledge AI Direct

EN-KS1-C026

Memorizing spellings of words that don't follow regular patterns

Teaching guidance

Teach Year 1 and Year 2 exception word spellings through daily practice using look-say-cover-write-check routines. Highlight the 'tricky' part of each word that does not follow phonics rules (e.g., the 'o' in 'one', the 'w' in 'two'). Display exception words prominently and refer to them during writing. Group exception words by common features where possible (e.g., words with 'ould': could, would, should). Assess regularly through dictation and ensure children can spell these words in their independent writing.

Vocabulary: exception word, tricky word, learn, remember, look-say-cover-write-check, practise, spell
Common misconceptions

Children often spell exception words phonetically (e.g., 'sed' for 'said', 'woz' for 'was') because their phonic knowledge overrides the irregular spelling. They may learn to read exception words but not be able to spell them from memory. Some children assume all frequently used words have tricky spellings, failing to recognise that many common words are fully decodable.

Difficulty levels

Entry

Reading and beginning to spell a small set of the most common exception words (the, I, to, no, go).

Example task

Look at the word 'said'. Cover it up. Now write it from memory.

Model response: Child writes 'said' correctly.

Developing

Spelling most Year 1 exception words correctly using look-say-cover-write-check strategies.

Example task

Spell these words without looking: 'was', 'you', 'they', 'are', 'were'.

Model response: Child spells all five words correctly from memory.

Expected

Spelling Year 1 and Year 2 exception words correctly in independent writing, not just in spelling tests.

Example task

Write a sentence about your weekend. Use at least two exception words correctly.

Model response: 'On Saturday I could not find my favourite shoes because they were behind the door.' (Exception words: could, find, favourite, because, behind used correctly.)

Greater Depth

Spelling exception words accurately and consistently, and identifying which part of each word is 'tricky'.

Example task

Circle the tricky part of each word: 'beautiful', 'because', 'Christmas', 'different'. Explain what makes each part tricky.

Model response: 'Beautiful — the "eau" makes an /oo/ sound, which is unusual. Because — the "au" makes an /o/ sound. Christmas — the "Ch" makes a /k/ sound. Different — the second "e" is easy to forget because you can't hear it.'

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Access barriers (1)
high
Working Memory Load

Learning exception word spellings requires rote memorisation of letter sequences that cannot be derived from phonics rules. Children with working memory difficulties need many more exposures and multi-sensory approaches (look-say-cover-write-check) to retain these spellings.

Suffixes

knowledge AI Direct

EN-KS1-C027

Word endings that change meaning or function (e.g., -s, -ed, -ing, -er, -est)

Teaching guidance

Introduce common suffixes systematically: -s, -es, -ing, -ed, -er, -est, -ly, -ful, -less, -ment, -ness. Teach the spelling rules that apply when adding suffixes (e.g., doubling the final consonant, dropping the final 'e', changing 'y' to 'i'). Use root word + suffix activities where children physically combine word cards. Teach the meaning each suffix adds (e.g., -er means 'more', -est means 'most', -ful means 'full of'). Ensure children practise using suffixed words in their writing.

Vocabulary: suffix, ending, -s, -es, -ing, -ed, -er, -est, root word, add, change
Common misconceptions

Children frequently forget to apply spelling rules when adding suffixes (e.g., writing 'hopeing' instead of 'hoping' or 'runing' instead of 'running'). They may not recognise that the root word is preserved within the suffixed form. Some children add suffixes incorrectly to exception words (e.g., 'goed' for 'went').

Difficulty levels

Entry

Adding -s to regular nouns and verbs to make plurals or third person forms.

Example task

Make these words plural by adding -s: 'cat', 'dog', 'cup'.

Model response: Cats, dogs, cups.

Developing

Adding common suffixes (-s, -es, -ing, -ed, -er, -est) to words without spelling changes.

Example task

Add the suffix to each word: 'jump + ing', 'tall + er', 'box + es'.

Model response: Jumping, taller, boxes.

Expected

Applying suffix spelling rules including doubling consonants and dropping final 'e'.

Example task

Add -ing to these words: 'hope', 'run', 'play'.

Model response: Hoping (drop the e), running (double the n), playing (just add -ing).

Greater Depth

Explaining suffix spelling rules and identifying the root word within a suffixed form.

Example task

The word is 'happiest'. What is the root word? What suffix was added? What spelling rule was used?

Model response: 'The root word is "happy". The suffix is "-est". The spelling rule is: when a word ends in a consonant + y, change the y to i before adding the suffix. So happy becomes happiest.'

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Prefixes

knowledge AI Direct

EN-KS1-C028

Word beginnings that change meaning (e.g., un-)

Teaching guidance

Introduce the concept of a prefix as a group of letters added to the front of a word that changes its meaning. At KS1, the most common prefix is 'un-' (undo, unhappy, unfair, unlock). Teach children that the prefix changes the meaning to the opposite. Use matching activities: pair words with their 'un-' form. Show that the spelling of the root word does not change when a prefix is added. This lays the foundation for the wider range of prefixes taught in KS2.

Vocabulary: prefix, un-, beginning, opposite, change meaning, root word, undo, unhappy
Common misconceptions

Children may confuse prefixes with the first letters of a word, thinking that any word beginning with 'un' has a prefix (e.g., 'under', 'uncle'). They may struggle to understand that 'un-' reverses meaning without changing the root word's spelling. Some children try to add 'un-' to words where it does not apply.

Difficulty levels

Entry

Understanding that adding 'un-' to the start of a word changes its meaning to the opposite.

Example task

What is the opposite of 'happy'? Add 'un' to the beginning.

Model response: Unhappy.

Developing

Using 'un-' with a range of adjectives and verbs to create opposites.

Example task

Add 'un-' to make the opposite: 'kind', 'lock', 'fair', 'do'.

Model response: Unkind, unlock, unfair, undo.

Expected

Using the prefix 'un-' correctly in own writing and recognising it in reading to work out word meanings.

Example task

You find the word 'unbreakable' in your reading book. You haven't seen it before. What might it mean? How do you know?

Model response: 'I can see "un" at the start which means "not", and "break" in the middle. So "unbreakable" means something that cannot be broken.'

Greater Depth

Distinguishing genuine prefixed words from words that simply begin with the letters 'un', and recognising that other prefixes exist.

Example task

Which of these words actually have the prefix 'un-': 'unhappy', 'uncle', 'under', 'unfair', 'until'? How can you tell?

Model response: 'Unhappy' and 'unfair' have the prefix 'un-' because if you take away 'un', you get a real word (happy, fair). 'Uncle', 'under' and 'until' don't have a prefix — they are just words that start with those letters.

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Root words

Keystone knowledge AI Direct

EN-KS1-C029

Base words before suffixes or prefixes are added

Teaching guidance

Teach root words as the base from which other words are built. Show children that adding suffixes or prefixes to a root word creates new words in the same word family (e.g., help → helps, helped, helping, helpful, unhelpful). Use word-building activities with cards or magnetic letters. When children encounter unfamiliar words in reading, prompt them to look for a root word they recognise. Display word families on classroom walls.

Vocabulary: root word, base word, word family, build, add, prefix, suffix, related words
Common misconceptions

Children sometimes identify a root word incorrectly by removing letters that are actually part of the base word (e.g., thinking 'butter' is 'butt' + 'er'). They may not realise that the root word carries the core meaning. Some children confuse root words with rhyming words or words that share initial letters.

Difficulty levels

Entry

Identifying the base word when a simple suffix is added.

Example task

What is the root word in 'jumping'?

Model response: Jump.

Developing

Identifying root words in words with common suffixes and the prefix 'un-'.

Example task

Find the root word in each: 'unhappy', 'played', 'tallest', 'careful'.

Model response: Happy, play, tall, care.

Expected

Using knowledge of root words to read and spell new words in the same word family.

Example task

If you know the word 'help', what other words can you make? Try adding different suffixes and the prefix 'un-'.

Model response: Helps, helped, helping, helper, helpful, unhelpful, helpless.

Greater Depth

Explaining how root words carry meaning through a word family and using this to decode unfamiliar words in reading.

Example task

You see the word 'mistreatment' in a book. You know the word 'treat'. How does that help you work out what 'mistreatment' means?

Model response: 'I know "treat" means how you act towards someone. "Mis" at the start means badly or wrongly. "Ment" at the end makes it a noun. So "mistreatment" means treating someone badly.'

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Plural formation

skill AI Direct

EN-KS1-C030

Adding -s or -es to make words plural

Teaching guidance

Teach the rules for forming plurals systematically: add -s to most nouns (cat/cats), add -es to words ending in s, sh, ch, x, z (box/boxes, church/churches), change -y to -ies when 'y' follows a consonant (baby/babies), and some irregular plurals (child/children, mouse/mice). Use sorting activities where children categorise words by their plural rule. Practise both reading and spelling plurals. Connect to grammar work on singular and plural nouns.

Vocabulary: plural, singular, one, more than one, -s, -es, -ies, add, change, noun
Common misconceptions

Children often apply the default -s rule to all words (e.g., 'boxs', 'churchs'). They may not change 'y' to 'i' before adding -es (e.g., 'babys'). Irregular plurals cause particular difficulty because they cannot be generated by rule (e.g., children may write 'mouses', 'sheeps', 'childs').

Difficulty levels

Entry

Making regular nouns plural by adding -s.

Example task

I have one cat. Now I have two... Write the word.

Model response: Cats.

Developing

Applying -s and -es rules correctly, knowing that -es follows words ending in s, sh, ch, x, z.

Example task

Make these words plural: 'bus', 'fox', 'church', 'hat'.

Model response: Buses, foxes, churches, hats.

Expected

Forming plurals correctly including changing -y to -ies and recognising common irregular plurals.

Example task

Write the plural of: 'baby', 'city', 'child', 'tooth', 'day'.

Model response: Babies, cities, children, teeth, days.

Greater Depth

Explaining plural formation rules and handling unusual cases including words that do not change in the plural.

Example task

Why is the plural of 'baby' spelled 'babies' but the plural of 'day' is 'days'? What is the rule?

Model response: 'When a word ends in a consonant + y (like baby: b is a consonant before y), you change y to i and add -es. When a word ends in a vowel + y (like day: a is a vowel before y), you just add -s.'

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Plural formation rules involve multiple patterns (-s, -es, -ies, irregular plurals) with context-dependent application. Children with SLCN may not hear the distinction between singular and plural in speech, making the written rules harder to learn.

Contractions

knowledge AI Direct

EN-KS1-C031

Shortened forms of words using apostrophes (e.g., can't, I'm, we'll)

Teaching guidance

Teach contractions by showing that the apostrophe represents the missing letter(s). Start with common contractions that children encounter frequently: can't (cannot), don't (do not), I'm (I am), it's (it is), didn't (did not), won't (will not). Use physical demonstrations: write both words, then show which letters are removed and replaced by the apostrophe. Display a contractions chart showing the full form and the shortened form side by side.

Vocabulary: contraction, apostrophe, short form, missing letter, cannot/can't, do not/don't, I am/I'm
Common misconceptions

Children frequently place the apostrophe in the wrong position because they do not understand it marks where letters have been removed. They may confuse contractions with possessives (e.g., mixing up 'it's' and 'its'). Some children omit apostrophes entirely when writing contractions or insert them randomly into words.

Difficulty levels

Entry

Understanding that a contraction is a shorter way of saying two words, with adult support.

Example task

I say 'can not'. What is the short way of saying it? Listen: can't.

Model response: Can't.

Developing

Reading and writing common contractions, placing the apostrophe in the correct position.

Example task

Write the contraction for: 'do not', 'I am', 'it is', 'we will'.

Model response: Don't, I'm, it's, we'll.

Expected

Using contractions accurately in own writing and explaining which letters the apostrophe replaces.

Example task

Write the contraction for 'they are'. Where does the apostrophe go? Which letter does it replace?

Model response: 'They're'. The apostrophe goes between the 'y' and 'r'. It replaces the letter 'a' from 'are'.

Greater Depth

Distinguishing between apostrophes for contraction and possession, and handling unusual contractions like 'won't'.

Example task

The word 'won't' is a contraction. Which two words does it come from? Why is it unusual?

Model response: 'Won't' comes from 'will not'. It's unusual because it doesn't look like you'd expect — it should be 'willn't' but instead the whole word changes to 'won't'. It's an irregular contraction.

Fine Motor Output Demand

Letter formation and handwriting IS the learning objective — this is construct-sensitive. Children with dyspraxia, hypermobility, or developmental coordination disorder need adapted tools (pencil grips, writing slopes, wider-ruled paper) rather than removal of the writing demand.

medium
Sustained Attention Demand

Handwriting practice requires sustained fine motor attention to letter formation, sizing, spacing and orientation. This is simultaneously physically and cognitively demanding. Children with ADHD find handwriting practice one of the most aversive school tasks.

Possessive apostrophes (singular)

Keystone knowledge AI Direct

EN-KS1-C032

Using apostrophe + s to show ownership (e.g., the girl's book)

Teaching guidance

Introduce the possessive apostrophe with singular nouns in Year 2. Teach that the apostrophe + s shows that something belongs to someone or something (e.g., 'the girl's bag' means the bag belonging to the girl). Use physical objects and labels to practise: hold up an item and ask 'Whose is this?' then write the possessive form. Contrast with plural -s to make the distinction clear. Practise in the context of sentence writing.

Vocabulary: apostrophe, possessive, belongs to, 's, owner, whose, singular
Common misconceptions

Children frequently confuse the possessive apostrophe with the plural -s, omitting the apostrophe entirely or adding one to all words ending in -s. They may place the apostrophe after the 's' even for singular nouns. The distinction between 'the dog's bone' (possessive) and 'the dogs run' (plural) is a persistent source of error throughout primary school.

Difficulty levels

Entry

Understanding that the apostrophe + s shows something belongs to someone, with physical objects as support.

Example task

This is the hat that belongs to the girl. How do we write that? 'The girl___ hat.'

Model response: The girl's hat.

Developing

Using apostrophe + s with singular nouns to show possession in simple sentences.

Example task

Rewrite using a possessive apostrophe: 'The bone belongs to the dog.'

Model response: The dog's bone.

Expected

Using possessive apostrophes with singular nouns accurately in own writing, distinguishing from plural -s.

Example task

Write two sentences: one where 'dogs' is plural and one where 'dog's' is possessive.

Model response: 'Three dogs played in the park.' (plural) 'The dog's tail wagged happily.' (possessive)

Greater Depth

Explaining the difference between plural -s, possessive 's, and contraction apostrophes clearly.

Example task

Explain the difference between 'the cat's bowl', 'the cats ran away', and 'the cat's sleeping'. What does the apostrophe do in each?

Model response: 'The cat's bowl' — the apostrophe shows the bowl belongs to the cat (possessive). 'The cats ran away' — no apostrophe, just plural, more than one cat. 'The cat's sleeping' — the apostrophe is a contraction of 'the cat is sleeping'.

Delivery rationale

Spelling/transcription concept — rule-based, pattern-based, ideal for spaced repetition and adaptive practice.

Homophones

knowledge AI Direct

EN-KS1-C033

Words that sound the same but have different spellings and meanings

Teaching guidance

Teach homophones at KS1 by focusing on common pairs that children encounter in their reading and writing: there/their/they're, to/too/two, here/hear, see/sea, be/bee, no/know, right/write, night/knight, blue/blew. Present each pair with clear definitions, pictures, and example sentences. Use fill-in-the-gap activities where children choose the correct homophone for the sentence. Display homophone pairs on a working wall.

Vocabulary: homophone, same sound, different meaning, different spelling, pair, which one, choose
Common misconceptions

Children commonly confuse 'there', 'their' and 'they're' because they sound identical. They may not understand why English has words that sound the same but are spelt differently. Some children learn one spelling and use it for all meanings. The apostrophe in 'they're' adds an additional complication.

Difficulty levels

Entry

Recognising that some words sound the same but are spelled differently, with common pairs.

Example task

Listen: 'see' and 'sea'. Do they sound the same? Do they mean the same thing?

Model response: 'They sound the same but "see" means to look and "sea" means the water at the beach.'

Developing

Choosing the correct homophone in a sentence for common pairs (to/too/two, here/hear, there/their).

Example task

Choose the right word: 'I went ___ the shop.' (to/too/two)

Model response: 'to' — 'I went to the shop.'

Expected

Spelling common homophones correctly in own writing by considering meaning in context.

Example task

Write three sentences, each using a different spelling: 'there', 'their', 'they're'.

Model response: 'The book is over there.' 'Their dog is called Rex.' 'They're going to the park.'

Greater Depth

Explaining the meaning difference between homophones and proof-reading own work to check homophones are correct.

Example task

Proof-read this paragraph and correct any homophone errors: 'There going too the beach. I can here the waves. Its going to bee a lovely day.'

Model response: 'They're going to the beach. I can hear the waves. It's going to be a lovely day.' Corrections: there→they're, too→to, here→hear, Its→It's, bee→be.

Spelling patterns and rules

knowledge AI Direct

EN-KS1-C034

Regular patterns in English spelling (e.g., doubling consonants, -tch endings)

Teaching guidance

Teach spelling patterns and rules explicitly within the phonics programme and beyond. Key KS1 patterns include: the /dʒ/ sound spelt as 'ge' and 'dge' at the end of words, the /s/ sound spelt 'c' before 'e', 'i' and 'y', the /n/ sound spelt 'kn' and 'gn' at the beginning of words, and the /r/ sound spelt 'wr' at the beginning of words. Use word sorting activities to help children identify and apply patterns. Practise through regular dictation and spelling tests.

Vocabulary: spelling rule, pattern, rule, sort, group, same sound, different spelling, silent letter
Common misconceptions

Children may overgeneralise a newly learned rule, applying it to words where it does not fit (e.g., using 'dge' in every word with a /dʒ/ sound). They may not recognise that some spelling patterns are position-dependent (e.g., 'ck' only appears after a short vowel). Some children learn rules in isolation but fail to apply them in independent writing.

Difficulty levels

Entry

Applying basic spelling patterns such as -ck after a short vowel in simple words.

Example task

Spell these words: 'back', 'duck', 'neck'.

Model response: Child writes 'back', 'duck', 'neck' with 'ck' correctly placed.

Developing

Applying KS1 spelling patterns including -tch, the /dʒ/ sound as 'ge'/'dge', and 'kn'/'gn' at word beginnings.

Example task

Spell these words: 'catch', 'badge', 'know', 'gnaw'.

Model response: Child spells all four words correctly.

Expected

Applying a range of spelling rules and patterns accurately in independent writing.

Example task

Write a sentence using at least two words with different spelling patterns you have learned (e.g., silent letters, -dge, -tch).

Model response: 'I knew the knight would catch the badge.' (kn-, -ight, -tch, -dge patterns)

Greater Depth

Explaining spelling rules and identifying when a pattern does or does not apply.

Example task

We use '-tch' in 'catch' but not in 'much'. When do we use '-tch' instead of '-ch'?

Model response: 'We use "-tch" after a short vowel sound: catch, match, fetch, stitch. But some common words are exceptions: much, such, rich, which. After a consonant or long vowel, we just use "-ch": lunch, teach.'
