All data on computers is represented as digits - that's why we call them digital devices! The digits on computers are incredibly simple - they have just two values (usually written as 0 and 1), because it's cheaper and faster to build devices that way. Using this two-digit (i.e. Binary) system is the basis of all data stored on computers, and all data transmitted on the internet. The Binary Representation activity explores how it is possible to represent all sorts of things - numbers, letters, dates and more - using such simple digits. At the same time, we'll be reinforcing some basic facts from mathematics, and getting a new view of our own decimal digit system.
