STEM
The language of the world, made learnable
Math, science, engineering, and data — built up from the very first idea, with a checkpoint after every lesson so understanding is earned, not assumed.
Pathways
Pick a destination, not just a topic
Each pathway is a guided journey across tracks — starting from shared math foundations and branching toward who you want to become.
STEM Starter
The foundation for everything else — build core math fluency, then learn to observe and explain the world like a scientist.
- 1Mathematical Foundations
- 2Science Explorer
Outcome: Reason with numbers and understand how the natural world works.
Future Engineer
Turn problems into prototypes. Pair mathematical thinking with the engineering design loop — define, build, test, iterate.
- 1Mathematical Foundations
- 2Engineering & Design
Outcome: Use math and the design process to build and improve real things.
Data & Decisions
From arithmetic to insight. Ground yourself in math, then learn to interpret data, spot misleading graphs, and judge the numbers behind the news.
- 1Mathematical Foundations
- 2Data Literacy
Outcome: Read, question, and reason with data and charts in everyday life.
Tracks
Four ways to think like a scientist
Start with Mathematical Foundations — fully interactive today — and grow into science, engineering, and data literacy.
Mathematical Foundations
From place value to algebra, geometry, and data — the everyday math that unlocks science, money, and engineering.
Start learningScience Explorer
How the world works: matter, energy, living things, and Earth — built on observation and the scientific method.
Engineering & Design
Solve real problems with the engineering design process — define, build, test, and improve.
Data Literacy
Read, question, and reason with data and charts — a survival skill for the modern world.
