How to Use AI to Create Lesson Plans (Any Subject)

October 2026  ·  11 min read

AI chat tools such as ChatGPT, Claude, Gemini and Copilot can draft a usable lesson plan in under a minute. But a vague request gets a generic plan, and a confident-sounding plan can still contain a wrong answer or an outdated exam detail.

This guide gives you a repeatable workflow, copyable prompts for five subjects, an error checklist, and the privacy rules to follow with real students.

Can AI actually write a good lesson plan?

Yes, as a first draft. AI is good at structure, at generating practice questions quickly and at rewriting material at different levels. It is weaker at knowing your exam board's current specification, getting multi-step answers right every time, and knowing what your student struggled with last week.

The rule: let AI do the drafting and volume work, and keep the judgement for yourself.

What is the step-by-step workflow for planning a lesson with AI?

This seven-step process works whether you teach Year 7 science, A2 Spanish or Grade 3 music theory.

1. Decide the objective yourself. Write one sentence: "By the end of the lesson the student can…". AI should not choose your learning goal.
2. Write a full brief. Include subject, level or grade, exam board if any, lesson length, one-to-one or group, online or in person, what the student already knows, and common mistakes you have seen.
3. Ask for a timed lesson flow. Request stages with minutes, teacher actions, student actions and a quick check for understanding in each stage.
4. Generate materials in separate prompts. Ask for questions, worked examples or texts one at a time. Shorter requests produce fewer errors.
5. Check everything. Solve every question yourself, verify facts against the specification or a textbook, and read texts aloud for level and tone.
6. Differentiate and set homework. Ask for support and stretch versions, then a short homework task linked to the objective.
7. Save your best prompts. Keep a prompt bank so next week's plan takes five minutes, not fifty.

What should I include in an AI lesson plan prompt?

The single biggest improvement you can make is a better brief. Here is a master prompt you can adapt for any subject:

You are an experienced [subject] teacher. Plan a [length]-minute [online one-to-one / group] lesson for a student at [level/grade, exam board]. Objective: by the end, the student can [objective]. They already know [prior knowledge] and often make this mistake: [mistake]. Give a timed plan with stages, teacher actions, student actions and one quick check for understanding per stage. Keep activities suitable for a shared screen. Do not invent exam details; if you are unsure of a specification point, say so.

Asking the tool to flag uncertainty does not make it reliable, but it makes it more likely to admit gaps.

What are good AI prompts for maths, science, languages, music and English?

Copy these, replace the brackets, and run them after your master prompt or on their own.

Maths prompt (e.g. GCSE)

Create 12 questions on [solving quadratic equations by factorising] for a GCSE [Foundation/Higher] student, ordered from easiest to hardest. Include two worked examples with every step shown, one common-misconception question, and one exam-style problem in context. Give a separate answer key with full working.

Then solve every question yourself before the lesson. Arithmetic slips in AI answer keys are common enough that checking is not optional.

Science prompt (biology, chemistry, physics)

Plan a 50-minute lesson on [osmosis] for a [GCSE combined science] student. Include a 5-question retrieval starter, an explanation using one everyday analogy, the required practical method with independent, dependent and control variables, three data-interpretation questions, and a 6-mark question with a marking guide.

Check the practical against your exam board's own required practical list, since names and methods vary between boards.

Languages prompt (any language, CEFR level)

Write a 150-word dialogue in [Spanish] at [A2] level about [planning a weekend trip] that naturally uses [the near future with "ir a"] at least six times. Then create: 8 comprehension questions, a gap-fill using the target structure, a 10-word vocabulary list with English translations, and three speaking prompts that make the student use the structure about their own life.

If you are not a native speaker of the language, have the text checked or compare it with a trusted source; AI can produce unnatural phrasing or mix regional varieties. For more language-specific ideas, see our guide to ChatGPT prompts for language teachers.

Music theory prompt (ABRSM / Trinity grades)

Plan a 30-minute online music theory lesson for a [Grade 2] student on [major key signatures up to two sharps and flats]. Include a quick recap game, a step-by-step method for working out a key signature, 10 practice questions written in text (name the key, name the scale degree), and a short listening or clapping activity the student can do at home.

AI tools cannot reliably draw notation, so ask for questions in words and write the staves yourself in notation software or on a whiteboard. Our guide to teaching music theory online covers what each grade includes.

English prompt (language and literature)

Plan a 60-minute lesson on [how Priestley presents responsibility in An Inspector Calls] for a GCSE English Literature student. Include a starter on key context, three short quotations to analyse (I will check them against the text), a model paragraph using point, evidence, analysis and context, a weaker paragraph for the student to improve, and a timed writing task.

Always check quotations against your copy of the set text. AI tools regularly misquote or invent lines from novels, plays and poems, and a misquoted line in an exam answer costs marks.

How do I check AI lesson plans for errors?

Treat AI output like a draft from a capable but overconfident trainee. Run through this checklist before any material reaches a student:

• Answers: solve every maths and science question yourself. Do not trust the answer key.
• Facts and dates: verify against a textbook, the exam board specification or another reliable source.
• Exam details: paper numbers, timings, mark allocations and command words change. Check the board's current specification and past papers, not the AI.
• Quotations and references: confirm every quote, author, title and source actually exists and is accurate.
• Level: read texts aloud. Is the vocabulary right for A2, Year 8 or Grade 3, or has the tool drifted upwards?
• Timings: add up the minutes. AI plans often squeeze 70 minutes of activities into a 45-minute lesson.
• Sensitivity: check scenarios suit your students' age and background.
• Online practicality: remove anything that needs physical cards, a lab or group work your format cannot support.

A useful trick is to paste the material back into a fresh chat and ask: "Check this for factual errors, wrong answers and level-inappropriate language. List anything you are unsure of." It is a second filter, not a replacement for your own check.

How can I use AI to differentiate a lesson?

Differentiation is where AI saves the most effort, because rewriting the same task three ways is slow by hand and quick for a machine. Try:

Rewrite this task in three versions with the same learning objective: (1) Support: sentence starters, a worked example and simpler numbers or vocabulary; (2) Core: as written; (3) Stretch: an open-ended or multi-step extension that requires explaining reasoning. Keep all three the same length so they can run at the same time.

Other differentiation prompts that work well:

• "Simplify this reading text to roughly [B1] level without losing the key ideas, and bold the five hardest words with definitions."
• "Write three hint cards for this problem, each revealing a little more, so the student can try before asking for the answer."

Describe needs in general terms rather than sharing diagnoses (see privacy below).

How do I use AI to generate homework?

Good homework is short, linked to the lesson objective and quick to mark. Ask for exactly that:

Based on this lesson plan, create a 20-minute homework task with: 5 retrieval questions on last week's topic, 6 practice questions on today's objective, and 1 challenge question. Add a mark scheme and list the three most likely mistakes with a one-line correction for each.

Mixing in earlier topics builds spaced practice into every assignment. Our ESL homework ideas post has more formats students actually finish.

How much time does AI save on lesson planning?

It depends heavily on the subject, your experience and how much checking the output needs. The table below shows illustrative ranges for an experienced tutor, not measured data. The right-hand column includes checking time, which is where most of your minutes should now go.

The biggest gains come from volume tasks; the smallest from anything needing exact accuracy, where checking takes nearly as long as writing.

Is it safe to put student information into AI tools?

Treat anything you type into a general AI chatbot as data leaving your control. Depending on the tool, your settings and your account type, conversations may be stored and may be used to improve the provider's models. If you teach in the UK or EU, UK GDPR or the EU GDPR applies to personal data about your students, and schools usually have their own AI policies.

Follow these rules:

• Never paste names, dates of birth, contact details, photos or school names. Use "Student A" or "a Year 10 student".
• Never share special category or sensitive information, such as SEND diagnoses, health conditions, safeguarding concerns or family circumstances.
• Do not upload students' work with identifying details. Remove names and anything that could identify them before asking for feedback suggestions.
• Check the tool's data settings. Many tools let you turn off use of your chats for training; business and education accounts often have stronger protections.
• Follow your school's or employer's AI policy, and use the tools they have approved where one exists.
• Tell parents and students if AI helps you create materials or feedback, especially for younger learners.

What does an AI-assisted lesson look like in practice?

Here is an example flow for a 50-minute online one-to-one GCSE maths lesson on simultaneous equations, drafted with AI and checked by the tutor:

• 0–5 min, retrieval starter: four AI-generated questions on rearranging formulae, answers checked beforehand.
• 5–15 min, explanation: two worked examples by elimination, written live on a shared whiteboard.
• 15–35 min, practice: eight questions in increasing difficulty, with the AI-written hint cards held back until needed.
• 35–45 min, exam-style problem: one worded problem in context, then the student explains their method aloud.
• 45–50 min, plenary: one exit question and the homework set.

Most of the planning time goes on solving the questions to check the answer key.

Should I use a chatbot or a ready-made curriculum?

Both have a place. A chatbot is flexible for one-off materials; a structured curriculum gives you sequenced lessons you do not have to verify from scratch. Many tutors use a curriculum as the backbone and AI for extra practice and differentiation. Derstina, for example, provides ready-to-teach lessons across languages, GCSE maths, science, music theory, English and more, with homework, student games and progress tracking built in. If you mainly teach languages, our guide on using AI to teach languages online goes deeper.

Frequently Asked Questions

Which AI tool is best for creating lesson plans?

General chatbots such as ChatGPT, Claude, Gemini and Microsoft Copilot can all draft solid lesson plans if you give them a detailed brief. The quality of your prompt matters more than the tool you pick. If your school provides an approved tool, use that one, because it is more likely to meet data-protection requirements.

Is it acceptable for teachers to use AI to plan lessons?

Yes, in most settings, as long as you check the output and follow your school's or employer's AI policy. AI is a drafting aid, and you remain responsible for the accuracy and suitability of anything you teach. Being open with parents and students about how you use it builds trust.

How accurate are AI-generated lesson plans?

The structure is usually sound, but individual facts, answer keys, quotations and exam details can be wrong. Errors are most common in multi-step maths and science answers and in quotations from set texts. Solve every question and verify every fact against a textbook or the exam board specification before teaching.

Can AI create lesson plans aligned to GCSE or other exam specifications?

AI can produce content that looks aligned, but it may not know the current version of a specific board's specification. Paste in or summarise the relevant specification points yourself and ask the tool to work from them. Then check paper structures, command words and required practicals against the board's own documents.

Can I put student names or SEND information into ChatGPT?

No. Avoid entering names, dates of birth, contact details, school names, diagnoses or safeguarding information into general AI tools. Describe needs in general terms, such as a student who finds long texts difficult, which gives the AI enough to adapt the material without sharing personal data.

How long does it take to plan a lesson with AI?

Once you have a saved prompt bank, a full lesson with practice questions, differentiation and homework can often be drafted and checked in 15 to 30 minutes. Most of that time should go on checking answers and adapting the plan to your student. The first few lessons take longer while you refine your prompts.
