How to use ChatGPT for lesson planning?

Sunday evening. On the desk, a pile of textbooks, notes, and a blank lesson plan template. Your mind is racing: how can I discuss a difficult topic in an interesting way? What exercises will engage the class? How can I adapt the materials for students with different needs? This is a universal experience for every teacher—a moment where the passion for teaching clashes with an overwhelming amount of administrative work. What if there were an assistant who could take over 80% of this tedious labour, freeing up your time and creativity?

Today, that assistant is ChatGPT for teachers—a tool that is revolutionising the way we approach lesson preparation. In this practical guide, I will show you how to go from a blank page to a finished, engaging lesson plan in just a few minutes. But I will also ask a key question: why is it that some teachers receive ready-made gems from AI, while others get generic and useless responses? The answer lies in one crucial skill that you need to know about.

Why is ChatGPT a game-changer for lesson planning?

Using artificial intelligence to create lesson plans is about much more than just saving precious time. Planning lessons with AI is a fundamental shift that brings three massive benefits to our work, affecting both the quality of teaching and our own wellbeing.

Firstly, we gain an inexhaustible source of creativity. We all have off-days when we struggle to come up with ideas for an interesting activity. ChatGPT acts as a tireless brainstorming partner, providing suggestions for games, debates, projects, or unconventional homework assignments on demand—breaking the routine and surprising both us and our students.

Secondly, we gain the ability to differentiate materials instantly. In the traditional model, preparing separate exercises for a gifted student and a student with learning difficulties means extra hours of work. AI allows this to be done in seconds, creating personalised learning paths and providing genuine support for every pupil. This is no longer just about automating a teacher’s work; it is intelligent personalisation on an unprecedented scale.

Finally, and perhaps most importantly, we save invaluable mental energy. By freeing the mind from repetitive, administrative tasks, we can focus entirely on the essence of our profession—building relationships with students, observing their progress, and being an inspiring guide for them.

Practical applications – From idea to finished lesson plan with ChatGPT

Let’s look at some specific examples of how you can create a complete lesson plan with ChatGPT in three simple steps.

Step 1: Generating the lesson outline and objectives

Instead of starting from scratch, start with a conversation with the AI. The key is to provide the right context. Write a precise prompt, including the lesson topic, the year group, the duration, and, if necessary, a reference to the national curriculum. For example: “Prepare an outline for a 45-minute history lesson for Year 8 on the causes of the outbreak of the First World War. Include lesson objectives, teaching methods, and the lesson procedure.” You can then ask for further clarification: “Formulate the lesson objectives in student-friendly language, e.g., ‘By the end of this lesson, I will be able to list three main causes of the conflict’.” This way, in just one minute, you have a ready-made AI lesson plan that serves as a solid foundation for further work.

Step 2: Creating engaging exercises and activities

Once you have the skeleton of the lesson, it is time to fill it with engaging content. Instead of scouring the internet for inspiration, ask your AI assistant. You could write: “Suggest three different activities for my lesson on the First World War:

1. Discussion questions for small groups.
2. A short quiz with five ‘true/false’ questions.
3. A creative homework assignment that does not involve copying from a textbook.”

ChatGPT will instantly generate ready-to-use materials that you can adapt or use in full, saving yourself an hour of preparation.

Step 3: Differentiating materials for students with diverse needs

This is where AI shows its true power. Imagine there is a key, but linguistically challenging, passage in the textbook about political alliances. You can copy it and prompt ChatGPT: “Simplify the text below so it is accessible for a student with dyslexia. Use shorter sentences and simpler vocabulary.” In the next step, using the same passage, you could ask: “Based on this text, create three critical thinking questions for a high-ability student that require analysis rather than just recall of facts.” This level of individualisation becomes simple, fast, and incredibly effective.

The limits of ChatGPT’s capabilities – The key lies in a good prompt

After this dose of optimism, we must be honest with ourselves. You have surely noticed that ChatGPT sometimes generates responses that are too vague, imprecise, or even contain factual errors. It is not a magic wand, but merely a powerful tool. And the quality of any tool’s work depends on the skill of the person operating it.

As it turns out, the quality of an AI-generated response depends 90% on the quality of the question asked. In the world of artificial intelligence, such a precise instruction is called a “prompt”. It is a detailed set of directions that tells the language model not only WHAT to do, but also HOW to do it, in what role, and for whom. The ability to write effective prompts—so-called “prompt engineering”—is becoming a key digital competency for the modern teacher today.
