Patterns & instructions
Practice sequencing, sorting, and describing how to get from here to there.
Open this pathway →A hands-on computing guide
Meet the tiny ideas that power big machines.
Start with 0 and 1. Explore how computers represent information, follow instructions, and build logic from simple parts.
Choose a path by age, then learn by trying.
Choose your starting point
Computing can grow with the learner.
Use the age pathways as flexible starting points. Every learner moves at a different pace, so follow the ideas that spark curiosity.
Bits & information
See how 0s and 1s can encode numbers, letters, and simple images.

How does a computer make sense of 0 and 1?
Binary is one way to represent information. A bit has two possible values, and groups of bits can stand for numbers, text, colors, and much more.
01 · Represent
Give information a form the computer can store and transmit.
02 · Combine
Use simple logic operations to make decisions from input bits.
03 · Build
Connect many small operations into circuits, memory, and processors.
04 · Explore
Test your ideas with visual tools and hands-on activities.
Make the invisible visible
Read a concept. Then change an input.
Binary Particles pairs clear explanations with small experiments. Convert a number to binary, toggle a logic gate, and observe how one change affects the result.
