How to use an AI lesson plan generator and get plans you can actually teach

An AI lesson plan generator can turn a topic into a full lesson plan in a minute or two. Used well, it saves hours. Used carelessly, it produces plans that look polished but don't fit your class, or that contain facts nobody checked.

This guide explains what these tools are good at, where they go wrong, and how to get plans you would actually teach.

What an AI lesson plan generator does

Most AI lesson planners use a large language model, the same kind of technology behind general chat assistants. You describe the lesson; the model writes a plan in a familiar structure: objectives, a starter, main activities, a plenary and perhaps differentiation and resources.

The best tools go further:

• they look the topic up in reliable sources before writing, rather than relying only on what the model remembers
• they show their sources so you can check facts
• they match the age, adjusting vocabulary, activity length and reading level
• they match your country, using local spelling, units, money and year-group names
• they keep the parts together, so the slides and worksheet follow the same plan

What AI does well

• Getting past the blank page. A decent first draft is quicker to improve than to write from nothing.
• Structure. AI is good at producing a clear, well-ordered plan with timings.
• Variety. Asking for several lesson ideas for the same topic can suggest approaches you hadn't considered.
• Adapting. Rewriting an explanation for a younger class, or adding a challenge task, takes seconds.

Where AI goes wrong

• Confident mistakes. Language models can state wrong facts fluently. Dates, figures, names and science explanations all need checking.
• The wrong level. A plan may pitch vocabulary or tasks too high or too low for your class.
• Generic activities. "Pupils discuss in groups" isn't a plan. Look for specific questions, examples and tasks.
• Unrealistic timings. Twenty minutes of activities squeezed into five is common.
• Missing misconceptions. AI may not anticipate the mistakes your pupils typically make; you know them better.

That's why the teacher stays in charge. The UK Department for Education's policy paper on generative AI in education recognises the potential to reduce workload, and stresses that the content AI produces still needs professional judgement.

How to write a good request

The more specific your request, the better the plan. Include:

Compare "Make a lesson on volcanoes" with "Year 5 geography, 50 minutes: pupils should be able to explain why volcanoes erupt, using the words magma, pressure and crust. They know the layers of the Earth already." The second will give you something much closer to what you need.

What to check before you teach it

Read the plan as if a trainee teacher had written it:

• Facts: check anything you aren't sure of against a reliable source.
• Level: would your pupils understand the words and manage the tasks?
• Timings: could this really be done in the time?
• The objective: does every activity move pupils towards it?
• The ending: is there a real check of learning, such as an exit ticket?

Our checklist for AI-made teaching materials goes through this in more detail, including slides and worksheets.

How Lesson Dino works

Lesson Dino is an AI lesson planner we built to make this checking easier. You type the subject, year group and topic, and choose your country. Then:

1. It looks the topic up first in Wikipedia and well-known learning sites for children and teenagers, and writes from what it finds. Sources are numbered, so you can check any fact. If it can't find good sources, it tells you.
2. It suggests nine lesson ideas, so you can pick the approach that suits your class.
3. It writes the lesson plan, with an objective, timings for each part and an exit ticket. Most parts have a Change button: tell the AI what to change and it rewrites just that part. Download it as Word or PDF.
4. It makes matching slides in one of 80 designs or your school's own PowerPoint template, which you can edit in the browser, present or download.
5. It makes a printable worksheet with an answer sheet, pitched at the right level for the age.
6. It finds videos, suggesting the best part of each clip to play.

Every lesson is saved as a project. If you make something again and prefer the old version, History lets you go back to it. Lesson Dino only needs the subject, year group and topic; you never type pupils' names or personal details.
