AI for teachers: lesson plans, rubrics and materials in minutes

Sunday afternoons have a particular flavor for many teachers: the endless list of things to prepare before Monday. A lesson plan, an evaluation rubric, a review activity, a simpler explanation for students who didn’t get it the first time. Hours that disappear into desk work instead of rest.

What you might not know is that a big chunk of that work can already be done by AI.

What AI can do for a teacher

Think of AI as a planning assistant that never gets tired and can revise its proposal as many times as you need. Given a topic, a grade level, and your learning objectives, an AI like Claude or ChatGPT can:

• Draft a complete lesson plan with objective, activities, and timing
• Create evaluation rubrics with specific criteria or competencies
• Generate discussion questions, quizzes, or exam-style assessments
• Adapt the same explanation to different comprehension levels
• Propose differentiated activities for groups with different needs

What used to take a full afternoon can now take ten minutes.

A real example: lesson plan from scratch

Imagine you’re going to teach a class on the water cycle with fourth graders. The flow is this simple:

1. You give it the context. You write: “I’m a fourth-grade teacher. I want a 50-minute lesson plan on the water cycle. The goal is for students to explain the stages: evaporation, condensation, and precipitation”.
2. AI returns a draft. With a clear objective, opening activity, development, closing, and suggested assessment.
3. You adjust it. “Change the closing activity to a drawing they do themselves” or “remove the video, I don’t have a projector this week”.
4. In ten minutes you have a plan. Not perfect, but 80% ready for your finishing touch.

The time you save isn’t the thinking time, it’s the typing time for what you already know.

Rubrics without starting from zero

Rubrics are one of the most time-consuming resources to create. To do them well you have to define criteria, describe performance levels, and make sure they’re clear to the student. AI does that scaffolding for you.

You write: “Create a rubric to evaluate a five-paragraph essay in middle school. Criteria: main argument, evidence, grammar, and organization. Four levels: excellent, satisfactory, developing, insufficient”.

You receive a ready-to-review table. You adjust the language to your context and you’re done. What used to take an hour now takes five minutes.

Differentiated materials for different levels

One of the biggest challenges in the classroom is addressing different learning paces. With AI you can request:

• The same explanation written at three difficulty levels
• A glossary of key terms for students who are further behind
• An extra challenge for students who finish first
• A simplified version of a text for students with reading difficulties

You don’t need to create four different materials from scratch. You create one and ask AI to adapt it.

What stays yours

AI doesn’t know what group you have, how your students learn, what happened last week, or what they struggle with most. You do. That’s why:

• The lesson plan it generates is a starting point, not the final product.
• You adjust the activities to your reality: your classroom, your materials, your time.
• No AI replaces your pedagogical judgment, it only accelerates it.

Use it for administrative and repetitive work, so your energy stays where it matters most: in front of your students.

Start this week

You don’t have to change your entire planning approach tomorrow. Choose the resource you hate preparing most (the rubric? the review quiz?) and let AI do the first draft this week.

If I, without being a teacher, can build tools with AI, imagine what you can achieve with years of classroom experience. You just have to start.
