Lesson slides in ChatGPT: one editable PowerPoint per lesson, the same structure all unit long

If you make slides for every lesson — Grade 7 science on Tuesday, Year 9 history on Wednesday, Lesson 4 of a unit that has three more to go — the SlideForge app in ChatGPT turns the lesson plan into a native, editable .pptx in under a minute. Start the message with @SlideForge, give ChatGPT the lesson, and name the slides: learning objectives, a Do Now, key vocabulary, how it works, a practice worksheet with answer boxes, an exit ticket. The layouts come from a catalog built for exactly these slides, your wording goes on verbatim, and the next lesson in the unit uses the same skeleton.

The lesson deck

A lesson's slides follow a skeleton that barely changes between Lesson 3 and Lesson 4: what we are learning today, a starter question while the class settles, the words we need, the idea explained, a worked example, practice, and a question to answer before the bell. What changes is the content, and rebuilding the same seven slides for every lesson is where the evenings go. Teachers are the largest group making slides with SlideForge — daily lesson slides and unit series most of all — and almost all of them arrive through ChatGPT. This guide is the workflow they use.

This lesson (about five minutes)

Enable the app first (search SlideForge in ChatGPT's apps, or open the listing and choose Try in chat). The first render asks you to sign in; the account starts with 60 free slides.

1. Give ChatGPT the lesson. Paste the lesson plan, or the page of the scheme of work, or just tell it the grade, the subject and the topic and ask it to draft objectives, an explanation and five questions first. Check the draft the way you would check a student teacher's.
2. Start the request with @SlideForge and name the slides by their job, not their design — the example below is enough.
3. Download the .pptx from the result card. The response lists, per field, what was bound as supplied. Open it in PowerPoint or Google Slides and change whatever you like; every word is a real text box.

What to write

@SlideForge Grade 7 science, Unit 2 Cells, Lesson 3:
diffusion and osmosis. Eight slides:

1. Cover: "Lesson 3 — Diffusion and osmosis", Grade 7 Science,
   Unit 2: Cells
2. Learning objectives: three "I can" statements
3. Do Now: "Why can you smell dinner from your bedroom?" —
   two minutes, write your idea in your book
4. Key vocabulary: diffusion, concentration gradient, osmosis,
   partially permeable membrane — one-line definition each
5. Diffusion vs osmosis, side by side: what moves, through
   what, driven by what, one everyday example each
6. Worked example: why a potato chip in salt water goes soft,
   in four steps
7. Practice: five questions, an answer box beside each
8. Exit ticket: "Explain in one sentence how oxygen gets from
   your lungs into your blood."

Slides render in parallel into one file with page numbers. The engine authors nothing of its own: the objectives, definitions and questions are the ones ChatGPT sends, and the fidelity report names any wording that was completed for you. For the answer key, follow up with "@SlideForge the same five questions with the answers, one slide" and keep that slide for yourself.

The layouts it picks

ChatGPT chooses from a catalog of 200+ maintained layouts. For a lesson you will mostly see:

• Practice prompt — one instruction or question given the whole slide. Do Now, think-pair-share, discussion question, exit ticket.
• Worksheet — an instruction plus two to eight questions, each beside a blank answer box for students to fill in. Practice, quick check, retrieval starter.
• Definition grid — each key term with its full name, a one-line definition and up to three explanatory lines. Vocabulary, the parts of a concept.
• Side-by-side contrast — two concepts as equals, each with a name, a tag and its points. Diffusion vs osmosis, metaphor vs simile, two characters, two theories.
• Steps beside a picture — a numbered procedure down one side and a picture you upload down the other. A worked example, a method, a lab procedure.
• Cycle and process diagrams — the water cycle, the rock cycle, a life cycle, a left-to-right process with what each stage produces.
• Era strip — history told as periods along a strip. A century in one slide, a civilisation's rise and fall, a technology's generations.
• Agenda and closing — today's lesson flow at the start, one line to leave on at the end.

Lesson 4: the same structure, new content

Stay in the same ChatGPT conversation and write "@SlideForge Lesson 4 of the same unit, active transport, same structure as Lesson 3:" followed by the new objectives, words and questions. ChatGPT sends the same layouts in the same order, and because the engine is deterministic — the same layout with the same input renders the same slide, and there is no model in the render path — the only thing that changes is the content. Students see the format they saw last lesson, and know where the exit ticket is going to be.

For a whole unit, give ChatGPT the four-week unit plan and ask for one deck per lesson. Each lesson is its own file, named the way you name them — Unit 2 · L03, Week 3 · Day 2 — and a unit of seven or eight lessons fits inside the 60 free slides.

In your language, or in two

Write the request in Portuguese, Spanish, Arabic or whichever language you teach in and the slides come out in it; the layouts are built for 35 languages, right-to-left scripts included, with the text fitted rather than cut. For a bilingual class or an English-learner group, ask ChatGPT to translate the finished deck: SlideForge translates the .pptx with the layout and formatting preserved, at $0.02 per slide, so the English and the home-language version of the same lesson match slide for slide.

Your school's template, if you have one

The built-in themes are free, and so is a school crest or logo on every slide: write "@SlideForge here is our logo" once and drop the file into the result card. If your school has a PowerPoint template it expects lessons to use, upload it the same way — "@SlideForge here is our school template, call it 'Lessons'" — and every deck from then on renders natively on its masters, cover and footer.

What else the app does in the same conversation

• Bring last year's slides in — drop a PDF of an existing lesson or a textbook page and get editable slides back, real text boxes and shapes, not a picture.
• A picture in the lesson — upload a diagram or photo and ask for it beside the steps or the explanation.
• Parents' evening, assembly, department meeting — the same catalog has agendas, timelines, comparison tables and status boards for the slides that are not lessons.
• Ask what it can draw — "@SlideForge what layouts do you have for a food web?" browses the catalog for free before anything is billed.

Why not let ChatGPT write the file itself?

ChatGPT can produce a .pptx by writing python-pptx code in its sandbox, and for one slide that is fine. For five lessons a week the difference matters: generated code takes minutes per deck, the layout varies from run to run so Lesson 4 never quite matches Lesson 3, text overflows its box with nothing to catch it, and non-Latin scripts are a gamble. The SlideForge app renders the wording ChatGPT sends into maintained layouts with overflow validation, in about a second per slide, and reports per field what happened. A slide with a blocking defect is not billed.
