BIT:BIT:BIT The Binary Code

How do we count using only 0 and 1 instead of numbers from 0 to 9?

While our decimal numbering system uses 10 digits, the binary system is a positional system in which only two digits 0 and 1 are used, and the values ​​of the digits depend on the powers of 2.

The children have access to simple machines that convert numbers from base 10 to base 2 and vice versa.

The simplest is the HAND-codifying machine: we learn with our hand to count with only 0 and 1.

Then there are the BOXES-converters: this game allows to convert numbers from decimal numbering system to corresponding numbers in the binary system.

Then using a program to convert even letters and words, all the names of participants are translated into binary code.   

Finally, friends and schoolmates can challenge to play the famous game of NIM, whose winning strategy is based on the binary number system.
