Week 6 - What is Binary

This week I have designed a binary game for children aged between 6 years and older.
Binary is a number system that has two unique digits. For most purposes, the decimal number system is used and has ten unique digits, 0 through to 9. All other numbers are then formed by combining these ten digits. All computers are based on the binary numbering system. Addition, subtraction, multiplication and division are all possible in the binary system. 
We use the decimal system in everyday life because it seems more natural as we have ten fingers and ten toes. The same with the computer, as the binary system is electrical nature as it is charged versus uncharged.
