Differentiating phonics resources for three or four groups is one of the most time-consuming jobs in early primary. AI can produce the variations in minutes — as long as you anchor it firmly to your scheme.
The one thing that makes this work
Phonics is systematic, and schools follow specific schemes with specific progression. Generic AI output ignores that entirely — it will happily use graphemes your children haven't been taught. So the essential move is anchoring every prompt to your scheme, phase and the exact sounds taught so far.
Always specify: your scheme, the phase or unit, the specific grapheme being taught, and — crucially — which graphemes have already been covered. Without that last one, AI produces words your children can't decode, which undermines the whole point of systematic phonics.
The core prompt
Prompt — base worksheet
Create a phonics worksheet for Year 1 pupils working on the grapheme 'ai'. We follow [your scheme] and pupils have so far been taught these graphemes: [list them]. Only use words that are decodable with those graphemes. Include: 8 words to read, 4 sentences to read, and 4 words for a dictation activity. Keep it appropriate for a 5-6 year old.
Creating the differentiated versions
Once the base sheet is right, ask for variations — this is where the time saving is largest.
Prompt — lower group
Create a simpler version of this worksheet for pupils who need more support. Fewer items, only CVC-length words with the target grapheme, more picture-matching style prompts, and simpler sentence structures.
Prompt — higher group
Create an extension version for pupils who are secure with this grapheme. Include longer words, some two-syllable words, and sentences requiring them to write their own answer rather than just read.
Prompt — pupils needing a different route in
Create a version for a pupil who finds written work difficult. Reduce the amount on the page, increase the space for writing, use a clear simple layout, and cut the number of items by half without lowering the phonics content.
Other phonics jobs AI speeds up
- Decodable sentences for any grapheme, restricted to sounds taught
- Word lists sorted by difficulty for assessment or intervention
- Parent guidance explaining a grapheme and how to practise at home
- Nonsense words for phonics screening practice
- Quick catch-up activities for a pupil who's missed a unit
Prompt — parent guidance
Write a short, friendly explanation for parents of how we teach the 'ai' grapheme, and three simple things they can do at home to help. Around 120 words, no educational jargon.
Always check before you print
AI makes two predictable mistakes with phonics: it slips in graphemes not yet taught, and it occasionally drifts into American pronunciation patterns that don't work for UK phonics. Read every word list before printing — it takes a minute and catches both.
The realistic saving
Producing three differentiated versions of a phonics sheet typically drops from 40+ minutes to under 10. Across a week of phonics, that's a genuine chunk of planning time back — see how to reduce teacher workload and personalising learning with AI.
Want your KS1 team saving hours on differentiation?
We show teachers the prompts that work with their actual phonics scheme. AskColin gives schools low-cost monthly support with one-to-one help whenever you need it — so when you're stuck on a real job at 8am, there's someone to ask. Practical, jargon-free, built around your team.

How can teachers use AI to make phonics worksheets?
Anchor every prompt to your scheme, phase, the target grapheme and — crucially — which graphemes have already been taught, so AI only uses decodable words. Create a base worksheet, then ask for simpler and extension versions. Three differentiated sheets typically drop from 40+ minutes to under 10.
Will AI use the right phonics progression?
Only if you tell it. Generic AI output ignores scheme progression and will use graphemes your children haven't been taught. Always list the graphemes covered so far and instruct it to use only decodable words — then check every word list before printing.
How do I differentiate phonics worksheets with AI?
Get the base worksheet right first, then ask for variations: a simpler version with fewer, shorter words and picture prompts; an extension with longer and two-syllable words plus written answers; and a reduced-load version with clearer layout for pupils who find writing difficult.
What mistakes does AI make with phonics resources?
Two predictable ones: slipping in graphemes not yet taught, and drifting into American pronunciation patterns that don't work for UK phonics. Reading every word list before printing takes a minute and catches both.
