Free AI Lesson Plan Generator for Teachers

Generate a single-class-period lesson plan in under two minutes — using the method your subject actually uses (5E for science, Workshop for ELA, Launch-Explore-Discuss for math, IDM for social studies, CLT for world languages, Gradual Release as fallback). Free for K-12 teachers.

How to Generate a Single-Class-Period Lesson Plan

  1. Enter Subject + Grade + Duration: Type your subject, pick grade and length (30 / 45 / 60 / 75 / 90 minutes). The method auto-suggests from your subject — "Biology" gets 5E, "Reading" gets Workshop, "Algebra" gets Launch–Explore–Discuss. You can override anytime.
  2. List Your Objectives: One learning objective per line (SWBAT... format works great). Add standards, upload a lesson doc if you have one.
  3. Get a Method-Faithful Lesson: Phases named for the method you picked (Engage / Explore / Explain for 5E; Mini-lesson / Independent Practice / Share for Workshop), minute-by-minute pacing, teacher and student actions, formative checks, and differentiation baked in.

Frequently Asked Questions

Which lesson-planning method should I use?

The tool auto-suggests based on your subject: 5E for science (recommended by NSTA/NGSS), Reading/Writing Workshop for ELA/literacy (TCRWP), Launch–Explore–Discuss for math (NCTM), Inquiry Design Model for social studies (NCSS C3), Communicative Language Teaching for world languages (ACTFL), and Gradual Release as fallback for skill/procedure lessons. You can override anytime — the picker shows a description of each method to help you choose.

Why not just use Gradual Release (I Do / We Do / You Do) for everything?

Because the standards bodies for each subject explicitly recommend different structures. NSTA warns that jamming science into I Do / We Do / You Do violates NGSS three-dimensional learning (students need to make sense of phenomena BEFORE the teacher explains). ACTFL requires ≥90% target-language use for world languages, which I Do / We Do / You Do undercuts. NCTM's Effective Mathematics Teaching Practices are task-first — students explore before the teacher shows a strategy. Workshop's whole innovation is teacher conferring during independent practice, which the gradual-release template erases. Gradual Release still works for procedure days and skill drill; the tool keeps it as an explicit option.

What if my lesson is longer than one class period (like a 5E unit)?

5E and Inquiry Design Model naturally span multiple class periods per their standards bodies. When you pick one of those, the tool generates a single-day slice — typically 2-3 adjacent phases from the full arc — with a note explaining which phases this lesson covers and where it sits in the larger sequence. To plan the whole unit at once, use the Unit Planner instead.

Can I upload my textbook or lesson notes?

Yes — upload PDFs, DOCX, or paste text. The AI reads your materials and grounds the lesson in what students have actually read. Source content is treated as data, never as instructions (so injection prompts in an uploaded doc can't hijack the output).

How is this different from the Unit Planner?

The Unit Planner is for full backward-design (Wiggins & McTighe's Understanding by Design) across multiple lessons — desired results, evidence, learning plan. The Lesson Planner is for tomorrow's class, right now — one class period, subject-appropriate structure, in under two minutes. If you've started a Unit in the Unit Planner, the Lesson Planner picks up context automatically.
