Building a lesson plan from the curriculum · AI for Teachers

The honest reason most teachers in Nepal do not write detailed lesson plans is not that they do not believe in them. It is that they teach five periods a day, six days a week, mark by hand, manage a class of forty-five children with one blackboard and a chalk box, and write the plan at ten at night when the load-shedding finally stops. The lesson plan is the first thing that gets traded away for sleep. This is the section where AI gives that hour back — not by writing the plan for you, but by doing the structural draft so you arrive at the page already at the interesting part: what your class needs tomorrow morning.

Five inputs, before you open the chat window

A generic prompt — “give me a lesson plan on photosynthesis for Class 8” — produces a generic output. It will look polished. It will be wrong for your room. Before you type anything, pin down five things:

1. The NEB learning objective, verbatim. Open the CDC curriculum page, find the specific objective for the unit (not the unit title, the objective), and copy it. For Class 8 science, the photosynthesis objective is roughly students will be able to describe the process of photosynthesis, identify its raw materials and products, and explain its importance for living beings. Paste this exact sentence into the prompt. The objective is the spine of everything that follows; without it the model invents one, and the invented one usually drifts toward the CBSE or American version of the topic.

2. The period length. In Nepal this is almost always 40 minutes in community and government schools, sometimes 45 in private English-medium. Double periods are rare and worth naming explicitly when you have them. The model needs the number, in minutes, because the only useful lesson plan is one with a time column.

3. The prior knowledge of this specific class. Not the syllabus prior knowledge — what your students actually retain. They covered cell structure last term but most of them cannot still draw a plant cell. They know “khana paani hawa” as the things living beings need but have not seen the word chlorophyll. Tell the model in one or two sentences. This is the input that separates a plan that lands from a plan that floats over the room.

4. The real ability mix in the room. A Class 8 government school section in Doti is not a Class 8 section in a Kathmandu boarding school, and neither is uniform inside itself. Name the mix honestly: forty-five students, roughly ten reading two grades below level, five who will finish any worksheet in half the time, the rest in the middle. This sets up the differentiation work in Section 3, but you also want the lesson plan to anticipate it.

5. What is actually in the room. Blackboard, chalk, the textbook, possibly one printer in the office that prints a single page per student if you ask the head teacher nicely. Not a smartboard. Not a projector. Not “students will research at home” — half of them do not have data at home. State this constraint in the prompt, and the model will stop suggesting QR codes and video clips you cannot show.

The fact-first prompt pattern

Once the inputs are pinned, the prompt itself follows a shape that is much closer to a contract than a question. Generic asks produce generic plans; named time segments and an explicit source-only instruction produce a usable draft.

You are helping a Class 8 science teacher in a Nepali community school plan a single 40-minute period on photosynthesis. The NEB learning objective is: [paste the objective verbatim]. Prior knowledge: students covered plant cell structure last term but recall is weak; most do not yet know the word chlorophyll. Class size 45, mixed ability (roughly ten students two grades below level, five who finish quickly). Available materials: blackboard, chalk, textbook page [number], one A4 print per student if needed. Produce a lesson plan with these named time segments: opening hook (5 min), concept explanation with blackboard diagram (12 min), two differentiated activities run in parallel (15 min), formative check (5 min), closing summary (3 min). For each segment, give: the teacher action, the student action, what goes on the blackboard, and the exact question the teacher asks. Use only facts that appear in the attached textbook page. Do not invent additional content. If a claim is not in the source, mark it [needs teacher check]. After the plan, list any term you used that is not in the source.

Three things in that prompt are doing the heavy lifting. The named time segments force the model to budget — without them you get a beautiful plan that runs for an hour and twenty minutes. The four-column structure per segment (teacher action, student action, blackboard, question) prevents the lesson from becoming a monologue on paper. And the source-only instruction — explicit, repeated, with a marker for items that fail it — is the single sentence that prevents the model from confidently teaching your students that photosynthesis happens at night.

A worked example: Class 8 photosynthesis

Fed the prompt above, with a Class 8 Science and Environment textbook page attached, a current model returns something close to this — abbreviated for space:

Opening hook (5 min). Teacher action: hold up a small potted plant and ask the class where the plant’s body came from. Student action: shout out guesses — soil, water, seed. Blackboard: write the three guesses in a column. Question: Bot bhaneko maato bata banchha ki, paani bata, ki kei aru bata? Concept explanation (12 min). Teacher action: draw a leaf cross-section on the board with sun rays, water from roots, air from stomata, and labelled products. Student action: copy diagram into notebook. Blackboard: the labelled diagram with the word equation paani + carbon dioxide + suryako prakash → glucose + oxygen. Question: Patta kun ranga ko hunchha, ra kina?

The output continues through the activities and the closing. It is not finished. It is a draft. Your job, before this lesson goes into the period, is the 5-minute review pass:

Read every fact against the textbook page. Is the word equation right? Does the textbook say glucose or carbohydrate? If the model said carbohydrate and your source says glucose, change it. Your students will be tested on the source.
Check anything tagged [needs teacher check]. Either delete it, or look up the answer and put it back in.
Translate the questions into the language your class actually thinks in. The model will write a question in formal Nepali; your Class 8 may speak Bhojpuri or Maithili at home. Adjust.
Cross out one thing. Every AI draft has at least one segment that is too clever, too long, or assumes a resource you do not have. Cutting it makes the lesson breathe.
Add one thing only you know. A local example. A previous misconception this class has had. The student who needs to be called on first because she is shy. The plan is not a plan until it has at least one sentence in it that the model could not have written.

In Lalitpur last term a teacher I watched do this caught the model claiming that “photosynthesis produces protein for the plant.” It does not. The textbook said glucose. The model, half-remembering a biology lecture from somewhere on the internet, had quietly upgraded the product. A five-minute review pass caught it. A blind paste would have taught forty-five children a wrong fact for the rest of the chapter.

When the textbook page is thin

NEB textbook pages are sometimes a single paragraph and a diagram. In that case the model has very little to ground itself on, and the temptation to invent is high. Two defences:

Feed it the adjacent pages too. The unit before and the unit after often contain the framing the model needs to stay tethered. Here is the page on photosynthesis; here is yesterday’s page on plant parts; here is tomorrow’s page on respiration. Three pages give the model the shape of where this lesson sits.

Cap the depth. Tell the model explicitly: do not go beyond the depth of this textbook page; if a concept appears here in one sentence, treat it as one sentence in the lesson, not as a paragraph. This prevents the model from importing a high-school treatment of photosynthesis into a Class 8 period, leaving your students confused and your time blown.

The 5-minute review is not optional

The review is the difference between AI as a lesson-planning tool and AI as a lesson-plagiarising tool. It is also the difference between a plan that survives contact with the classroom and one that collapses by minute twelve. Budget five minutes for it. Do it on paper, with the textbook open, before the lesson, not during. Teachers who skip the review tell me, after a term, that the time savings disappeared — because every other class brought a “the AI said this but actually…” question they had to handle live.

The right mental model is the same one the bookkeeping section uses for OCR drafts: the AI produced a draft; you are the senior who signs it before it goes into the room.
