Lesson plan prompt builder
Asking an LLM to “make a lesson plan about photosynthesis” gives you something usable but generic — no clear objectives, no timing, no differentiation, no aligned assessment. The lesson plan prompt builder turns your inputs into a precise prompt that asks the model for a complete, professional lesson plan with every section a teacher actually needs. It runs entirely in your browser, no API key required.
How it works
You provide the subject, student level, duration, learning objectives, and assessment type. The builder composes a prompt that instructs the model to produce:
- Learning objectives written as measurable outcomes.
- Prerequisite knowledge so the lesson starts at the right point.
- Materials and preparation the teacher needs in advance.
- A timed activity sequence that fits the duration — opening hook, instruction, guided practice, independent work, and closing.
- Differentiation for learners who need support or extension.
- An assessment of your chosen type, explicitly aligned to the objectives.
Writing learning objectives that actually guide the plan
Learning objectives are the engine of a good lesson plan. Vague objectives produce vague activities and assessments that cannot be measured. Strong objectives name a specific, observable behavior the student will be able to perform by the end of the lesson.
Compare:
- Topic-as-objective (weak): “Students will learn about the water cycle.”
- Observable-outcome (strong): “Students can label the four stages of the water cycle and explain how energy drives each transition.”
The second version tells the model exactly what activities to design (labeling, explaining cause-and-effect) and what the assessment should test. Use action verbs like “explain,” “calculate,” “compare,” “construct,” or “evaluate” rather than “understand” or “know,” which cannot be directly observed or measured.
Matching assessment to level and objective
| Student level | Assessment types that fit well |
|---|---|
| Early primary (ages 5–8) | Formative check-ins, thumbs up/down, drawing, teacher observation |
| Upper primary (ages 9–11) | Short quiz, paired discussion, exit ticket |
| Secondary (ages 12–18) | Written response, project, peer assessment, problem sets |
| University / adult | Essay, lab report, presentation, portfolio |
| Professional training | Scenario simulation, case study, observed practice |
Set the assessment type in the builder to match your level. The prompt then aligns the assessment back to the learning objectives so it tests what the lesson actually taught, not what happened to come up in conversation.
Tips for building a plan that works in the classroom
Write objectives as outcomes, not topics: “students can explain how chlorophyll captures light energy” beats “photosynthesis.” That single change makes the whole plan tighter because the model aligns activities and assessment to a measurable target. Use the timed activity sequence as a pacing guide — if a 45-minute lesson has a 35-minute instruction block, that is a flag. For a unit rather than a single lesson, set a longer duration and ask the model to break it into sessions; the section structure carries across each one. Always have the responsible teacher review the plan for accuracy, age-appropriateness, and safety before using it.
