Free learning resources & a modern AI curriculum — for any classroom, including the one at home.
The Open Classroom is a free, hand-verified directory of 593 learning resources across 10 subjects, plus an age-by-age (K–12) curriculum for teaching kids to use AI well. I built it for my own homeschooled kids — then added the part the internet is still missing and opened it to everyone.

The AI Track — teach your kids to use AI safely, creatively & well

Questions
Frequently asked
Is The Open Classroom really free?
Yes — completely. All 593 resources are free or have a genuinely useful free tier, the AI curriculum and prompt packs are free, and there are no accounts, sign-ups, or paywalls on this page. It's a public service, not a product.
What ages is the AI curriculum for?
All of K–12. The AI Track is laddered into four stages — K-2 (supervised curiosity), 3-5 (guided), 6-8 (creator), and 9-12 (independent) — so the guidance matches what's developmentally appropriate at each age, from a parent driving at age 5 to teens using AI critically by 18.
How do I teach my kid to use AI safely?
Start with the six safety ideas on this page: AI hallucinates, it's biased, never share private details, be honest about AI help, seeing isn't believing, and don't outsource your thinking. Then use the supervised, age-appropriate activities in the AI Track and the Parent Prompt Packs that make AI teach instead of just answer.
What are the best free homeschool resources?
This directory curates 593 hand-verified free resources across 10 subjects — reading, math and full courses, coding, science, languages, art and music, virtual museum tours, virtual field trips, printables, and AI-for-kids tools. Standouts include Khan Academy, Project Gutenberg, PhET, Scratch, and Smithsonian, alongside many lesser-known gems.
Who made The Open Classroom, and can I trust the links?
It was built by Peter Saddington — an AI advisor and homeschooling parent — originally for his own kids. Every one of the 593 links was opened and checked by hand, dead links were fixed or replaced, and paywalled relics were removed. Found something we're missing? You can email it in.
Can teachers and schools use it?
Yes — every resource works in a real classroom, and the AI curriculum is free for teachers to use. Schools that want the AI piece delivered as staff training or professional development can reach Peter through his AI training page.
Watch
The Council reviews The Open Classroom
Four AI agents tour the page and react — dryly, and a little out of their element on a children's learning site.
Who this is for
🏡 Homeschool parents
A complete free starting library plus the AI guidance no curriculum publisher has shipped yet. Bookmark it, work down it.
🍎 Teachers & districts
Every resource works in a real classroom. Want the AI curriculum delivered as PD or a workshop for your staff? That's what I do — let's talk.

Curated by Peter Saddington — AI advisor, builder, and homeschooling dad. Originally assembled for his own kids; rebuilt, re-verified and AI-upgraded for everyone, June 2026. Every one of the 593 links opened and checked by hand.Parent to parent: don’t try to do all 593 — pick one tonight, follow your kid’s curiosity, come back tomorrow. The AI Track is the part I’m proudest of: it’s free because every kid deserves a calm, honest way to grow up with AI, not behind it. Found something we’re missing? Send it over — I read every one.
