AI-written overview

What is it?

Binary numbers (unit) is part of a CS Unplugged unit about binary numbers. Binary is how computers store numbers using only two states, on and off. The activities use cards, movement and games, with no screen.

Is it for me?

It is made for children about 5-7 and up, and it is meant to be done together with a grown-up or teacher. You do not need to know any coding. It is a Beginner activity.

Grown-ups: these are teacher and parent lesson plans. Be the guide, let the child discover patterns, and do not worry about correct answers at first.

How to start

  1. Ask a grown-up to read the lesson or open our simple version with you.
  2. Gather what you need, like paper cards with dots, and clear a little space.
  3. Do the activity together and say out loud what you notice.

How much time?

Most lessons take 30 to 60 minutes. Plan about 15 minutes for a session. (estimate)
