Plan entire units — or your whole course

Stop building lessons one at a time with no bigger picture. Upload your district's pacing guide or scope-and-sequence and the Course Planner maps every topic for you. Then build each lesson straight from the plan — your whole course stays organized in one place with progress you can see at a glance.

Start from your curriculum

Upload your pacing guide, syllabus, or scope-and-sequence (PDF, photo, or pasted text) and every topic is mapped for you — up to 120 topics per course.

Or plan your own sequence

Pick a subject and grade and let AI suggest a topic sequence, or type your own. Edit, reorder, add, or remove topics until it matches your scope.

Build every lesson

Generate each lesson directly from the plan. Every lesson auto-files into the unit folder with the right topic and standards.

Track your progress

See which lessons are built and which are still planned. Pick up right where you left off.

Three Steps to Your Ready-to-Teach Lesson

Step 1

Set Your Vision

No prompt crafting, no AI expertise. Just pick your topic, grade level, class length, and framework. The engine already knows how to turn those choices into a structured lesson.

Step 2

Your Lesson Takes Shape

In minutes, your choices become a fully structured lesson plan, assessment with parallel forms, or targeted assignment, complete with answer keys.

Step 3

Make It Yours

Swap problems, adjust difficulty, differentiate for your learners, then print or share with your team.

New · Whole-lesson differentiation

Differentiate every lesson in one pass

You built the lesson for the whole class. Now build a parallel support track for the students who need it, without rewriting a thing yourself. Same concepts, same objective, a gentler on-ramp.

Step 1

Review the whole lesson

Open one panel that lists every task, warm-up, exit-slip, and homework problem: the entire lesson in front of you at once.

Step 2

Get smart suggestions

Each problem is read for its type and pre-matched to a support strategy: chunking, sentence starters, vocabulary banks, worked examples, friendlier numbers, plus dedicated multilingual (English-learner) and IEP accommodation supports.

Step 3

Generate in one click

Apply supports across the lesson in a single pass. A scaffolded support version is added next to every original. The math stays the same.

One panel reads every problem, matches a support strategy, and generates a scaffolded version for each, in a single pass.

Same problem · two versions, side by side

Original: class copy

A recipe uses 3/4 cup of sugar for every 2 cups of flour. If a baker uses 9 cups of flour, how much sugar is needed?

Support version: broken into steps

A recipe uses 3/4 cup of sugar for every 2 cups of flour. A baker uses 9 cups of flour.

  1. How many “batches” of 2 cups are in 9 cups of flour?
  2. Each batch needs 3/4 cup of sugar. Multiply your answer by 3/4.
  3. Write the total cups of sugar: __________

Frequently Asked Questions

Everything teachers ask before getting started.

Explore our research-informed teaching framework guides →

Yes, creating an account is free, and you can build STEM lessons and browse the entire public lesson library at no cost. Upgrading simply removes the limits: you get much higher creation limits, one-click printable and PDF exports of student handouts and answer keys, plus time-saving tools like photo import (turn a worksheet photo into an editable lesson) and ready-made assessment banks. Most teachers upgrade once they’re using STEMEngine for their weekly planning and want everything print-ready without caps.

A thin-sliced lesson breaks a concept into a sequence of small, gradually escalating tasks so students build understanding step by step, from initial exploration through to mastery. It’s ideal for Building Thinking Classrooms and inquiry-based teaching.

Yes, and not just to a single standard set. Lessons can be aligned to Common Core Math, NGSS, state-specific standards, TEKS, IB, and essentially any framework you teach to. Each lesson displays its target standard code alongside the pedagogical approach, and you can specify whichever standards your district or country uses so the alignment matches your context.

STEMEngine AI covers Mathematics and Science, including algebra, geometry, calculus, statistics, biology, chemistry, physics, and earth science, from elementary through high school and introductory college.

Absolutely. You can differentiate an entire lesson in one pass, generating scaffolded support versions (chunked steps, sentence starters, vocabulary support, worked examples, cloze, reduced computation) alongside the original, then print both as ready-to-hand-out class and small-group copies.

STEMEngine isn’t limited to a fixed menu: it can structure a lesson around virtually any research-based pedagogy you name, including hundreds of frameworks and instructional models. Popular built-in options include Thin-Slicing, Building Thinking Classrooms (BTC), the 5E Model, POGIL, NGSS Phenomenon-Based learning, Claim-Evidence-Reasoning (CER), Problem-Based Learning, and Discovery/Inquiry. But if you teach with a different approach, just ask for it and the lesson’s structure, consolidation, and teacher notes adapt accordingly.

Yes. Alongside full lessons, the Quick Assign tool builds ready-to-run classroom routines in seconds — a five-day Spiral Review of mixed, cumulative skills, a Number Talks string for mental-math discussion, and the 3 Reads protocol for math word problems. Each comes with discussion prompts and answer keys, and can be projected on-screen or printed for students.

Yes. The Course Planner lets you upload your district's pacing guide, syllabus, or scope-and-sequence as a PDF, photo, or pasted text. It maps every topic automatically — up to 120 per course — and you can build each lesson straight from that plan. Your district's sequence stays intact; the AI just builds the materials to match it.

Absolutely, you’re in full control. Every task, warm-up, exit slip, and homework problem is fully editable. Swap in your own problems, insert custom tasks, adjust difficulty, or regenerate a single item, without rebuilding the whole lesson.

You can print student handouts (with or without answer keys), export to PDF, or share a live student link. Quick Assignments can also be shared as interactive links students complete on any device.
