Lesson plan prompt
A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional lesson plan on the first try, plus the cheapest model that does it well.
What most people type
lesson plan for 7th grade science on the water cycle, 50 minute class
It works, but the AI has to guess your standards to align to, class size and available materials or technology, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.
The better prompt
Create a lesson plan for a 7th grade science class on the water cycle. The class period is 50 minutes. Structure it the way teachers plan lessons: - Learning objectives (2-3, measurable) and [standards to align to] - Materials and prep - Timed agenda that adds up to 50 minutes: opening hook or warm-up, direct instruction, a hands-on or collaborative activity, a check for understanding, and a closing/exit ticket - Key vocabulary with student-friendly definitions - Common misconceptions to address - Differentiation: support for struggling students and extension for advanced students - Assessment: how to tell whether students met the objectives, with a short answer key for any questions - Optional: homework or follow-up Class details: [class size], [available materials or technology], [students' prior knowledge of the topic]. Keep activities realistic for a standard classroom. Format as a clear outline with a timing table for the agenda.
Replace the [brackets] with your details before you send it: standards to align to, class size, available materials or technology, students' prior knowledge of the topic.
Why this version works
- Added standard lesson plan sections. Matches what teachers actually need to run the class
- Required timed agenda totaling 50 minutes. Keeps the plan usable within the class period
- Added differentiation and assessment. Covers mixed ability and checks objectives were met
- Added placeholders for class details. Standards, size and materials change the plan
