Lesson Planning with AI

The Lesson Planning Problem

Every teacher knows the feeling: it is Sunday evening, you have five classes tomorrow across three different grade levels, and you need differentiated lesson plans for each. The planning itself takes longer than the teaching. AI does not eliminate planning — but it compresses the mechanical parts so you can focus on the creative and relational parts that only a human can do.

Understanding by Design (UbD)

Before we bring AI into the picture, let us ground ourselves in a proven framework. Understanding by Design (Wiggins & McTighe) — sometimes called "backwards design" — structures lesson planning into three stages that start with the end in mind:

Most teachers plan forward: "I will cover Chapter 7 on Monday." UbD flips this: "By Friday, students should be able to analyze primary sources from the American Revolution and construct an evidence-based argument. The evidence will be a document-based essay. So Monday through Thursday needs to build toward that skill."

When prompting AI, UbD is your secret weapon. Instead of asking "Give me a lesson on photosynthesis," try: "I need students to be able to explain the role of chlorophyll in photosynthesis and design a controlled experiment by Friday. Plan four 50-minute periods that build toward this outcome, with a formative check each day. Align to NGSS MS-LS1-6."

Traditional vs AI-Assisted Lesson Planning

Here is what changes — and what stays the same — when you bring AI into your planning process:

The time you save on mechanical tasks goes directly into the work that matters: thinking about Aiden who needs extra support with reading comprehension, planning the group activity that will draw out quiet Maya, or preparing IEP-aligned materials for Jayden's 504 accommodations.

Aligning to Standards

Whether you are working with Common Core, NGSS, state-specific standards, or the UK National Curriculum, referencing standards explicitly in your prompts produces dramatically better results. Here is a template:

Standards: CCSS.ELA-LITERACY.RI.8.6 (determine author's point of view)
Grade: 8
Subject: English Language Arts
Unit: Analyzing Persuasive Texts
Learning Targets:
- Identify rhetorical strategies in persuasive writing
- Evaluate the effectiveness of an author's argument
- Construct a written response using text evidence

Create a UbD-aligned lesson plan for three 50-minute periods.
Include: one close reading activity, one Socratic seminar prompt,
and a 3-question formative exit ticket aligned to these targets.

The more specific your prompt, the more useful the output. Check data/curriculum-standards.json for pre-mapped standards across ELA, Math, and Science for Grades 6-10 — including Common Core, NGSS, and UK National Curriculum equivalents. You can copy-paste these directly into your prompts.

For UK teachers: the National Curriculum uses Key Stages rather than grade levels. When prompting, specify "Year 9, Key Stage 3" rather than just "Grade 8." For Australian teachers, reference the ACARA content descriptors (e.g., "ACMNA187 — Solve problems involving profit and loss").

Differentiation Made Practical

In a class of 25 students, you typically have three broad groups:

Without AI, creating three versions of a worksheet takes an hour. With AI, you can generate all three in one prompt:

Topic: Area of triangles (Grade 7, CCSS 7.G.B.6)

Create three versions of a 10-question worksheet:
Version A (Support): Use simple numbers, include diagrams with
measurements labeled, provide the formula at the top. Use Lexile
level 700-800.
Version B (Core): Standard grade-level problems, mix of diagram
and word problems.
Version C (Extension): Include composite shapes, real-world
contexts (calculating the area of an irregularly shaped garden,
estimating paint needed for a triangular wall), and one question
that requires students to create their own problem.

Review the output carefully. AI sometimes makes Version A too easy (just plug-and-chug) or Version C too hard (jumping to concepts not yet taught). Your expertise in knowing what your students can handle is irreplaceable.

Lesson Plan Templates

Look at data/lesson-plan-templates.json for six ready-to-use templates:

Each template includes the prompt you should send to AI, the fields it will fill in, and a checklist for reviewing the output. Start with these templates rather than writing prompts from scratch — you can customize them as you gain confidence.

SEL Integration

Social-emotional learning (SEL) is increasingly embedded in US, UK, and Australian curricula. AI can help you weave SEL into academic lessons:

Prompt:

"I am teaching a Grade 6 ELA unit on personal narratives. Suggest 3 ways to integrate CASEL SEL competencies (self-awareness and relationship skills) into the writing process. Include one journal prompt, one peer feedback protocol, and one reflection activity."

This is especially valuable for MTSS Tier 1 (universal supports) — embedding SEL into daily instruction rather than treating it as a separate program.

Common Mistakes to Avoid

Mistake 1: Accepting the First Output

AI gives you a draft, not a finished product. Always read through the entire lesson plan. Check that the difficulty matches your students, the examples are culturally relevant, and the time estimates are realistic for your classroom.

Mistake 2: Ignoring the Textbook

AI does not have access to your specific textbook edition. It may reference different page numbers, use slightly different terminology, or structure topics in a different order. Always cross-reference with your adopted curriculum materials.

Mistake 3: Over-Planning

A beautifully detailed 5-page lesson plan is useless if you cannot execute it in a real classroom with 28 students at different levels and a fire drill in the middle of Period 3. Keep plans concise. The best AI-assisted plans are one page: objectives, activities, materials, assessment, and a backup plan if technology fails.
