Teaching children how the world actually works.
A structured curriculum for families who take thinking seriously. Ages 8–16. No specialist background required.
The problem
Most curricula teach facts. This one teaches structure.
Public and private school curricula emphasise facts, memorisation, and test performance. If you're homeschooling, you have more freedom — but you still need to know what to teach.
Almost none of the existing curricula teach children how the world actually works: how patterns permeate reality, how causes produce effects, how explanations simplify (and distort) reality, and how every decision involves a tradeoff.
Can your child explain the difference between:
- A coincidence and a cause?
- A good guess and a lucky one?
- A model and the thing it describes?
These aren't trick questions. They're the foundations of clear thinking — and almost no curriculum teaches them explicitly.
What we teach
Five structures that govern reality
Every module in the curriculum is built around one of these five ideas. A child who understands all five will think differently — about science, history, their own decisions, and other people's arguments.
Patterns
The world has structure. Knowing how to spot it — and when apparent patterns are noise — is the first cognitive skill.
Causality
Understanding something means understanding what produces it. Causes, mechanisms, chain reactions, and the difference from coincidence.
Uncertainty
The future is not predictable — but some guesses are better than others. Probability, risk, and thinking clearly under incomplete information.
Models
Every explanation is a simplification of reality. Learning to build, test, and critique models is how good reasoning works.
Decisions
Every choice forecloses other choices. Tradeoffs, incentives, long-term thinking, and how to make decisions that hold up under pressure.
The curriculum
Three levels, nine modules, 52 lessons each
One lesson per week. Each module is a standalone book.

Applying Thinking to Real Decisions
Who this is for
Homeschooling families
You've taken charge of your child's education. This is the curriculum most schools don't have — structured, serious, and ready to teach.
Parents supplementing school
One lesson per week sits alongside any existing school schedule. The material doesn't overlap with what school teaches — it fills the gap.
Tutors and educational coaches
Full lesson plans with discussion questions and exercises. No specialist background in philosophy or logic required to teach.
The founder
"I designed this curriculum because I couldn't find one that taught my child how the world actually worked — not facts about it, but the structures that explained how and why things happened the way they did."
Eldar Sarajlic is a philosopher, academic, and parent. He has taught logic, critical thinking, and philosophy at the university level for over a decade. The School of Critical Thinking is built on the same rigorous foundations — made accessible for children from age 8.
