Whose cake is it 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 8-10 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.
