Use when a teacher, tutor or student asks for slides for a lesson, lecture, class, unit, lesson plan, homework explainer, or a school or college project presentation.\n---\n\n# Lesson and school presentations\n\n## Pick the variant\n- **Teaching deck** (teacher or tutor): use the structure below.\n- **Student presentation** (school or college project, report, book review): intro →\n  background → main points (2–4 slides) → findings or opinion → conclusion → sources slide.\n\n## Teaching structure (default 8 slides; scale to the user's number, max 30)\n1. Title and learning objectives (2–3, \"Students will be able to…\")\n2. Hook: a question, surprising fact or scenario\n3–5. Core concepts, one idea per slide\n6. Worked example\n7. Activity or discussion prompt\n8. Check for understanding (3 quick questions, answers revealed on click) and recap\n\n## Building the call\n- `topic`: subject, grade or level, and the structure above as a compact numbered list.\n- `audience`: map grade to `high_schoolers` or `college_students`. For younger grades,\n  use custom text such as \"grade 5 students\".\n- `tone`: `academic` for college; for younger students `conversational`, unless the user\n  says otherwise.\n- `text_content`: `concise` unless the user wants handout-style detail (`detailed`).\n\n## After creating\n- Offer speaker notes for the teacher: call `edit_presentation` with\n  \"add speaker notes to every slide with what to say and timing\".\n- For an end-of-lesson quiz, build a separate quiz deck with havi-quiz-deck.\n- There is no worksheet or handout export — do not promise one.\n"
