A standard structure, ready to fill in
This builds a lesson plan skeleton using a standard structure (warm-up, direct instruction, guided practice, wrap-up/assessment) with time allocations automatically proportioned from your total lesson duration. Your subject, topic, objectives, and materials are dropped into place.
This provides the structure and timing - the actual content of your main activity, the specific examples you will use, and your assessment questions still need your own subject expertise, since only you know what will genuinely work for your students and material.
Why the four-part structure stays the same regardless of subject or grade level
Warm-up, direct instruction, guided practice, and wrap-up/assessment is a widely used lesson structure precisely because it fits almost any subject and age group - the proportions this tool uses (roughly 10%, 55%, 20%, and the remainder) are a reasonable starting default, not a rule, and adjusting them to match your own teaching style or a particular lesson's needs is expected.
Why time allocations are calculated automatically from your total duration
A fixed set of minute values wouldn't scale correctly between, say, a 30-minute lesson and a 90-minute block - calculating each section as a percentage of your actual lesson length means the structure stays proportionally sensible regardless of how long or short your specific lesson period runs.
Why this intentionally stops at structure rather than generating teaching content
The actual substance of a lesson - the specific examples, the exact questions to ask, how to explain a concept to this particular group of students - depends on expertise and context that only the teacher actually has. This tool handles the organizational scaffolding so that expertise can go directly into the content, rather than being spent on reformatting a plan from scratch each time.
