Writing Messages in Binary
Binary code is a system that only uses 0’s and 1’s. 0 essentially means off and 1 means on. Using this in
a sequence of eight can be related to letters and numbers and used to create commands for a
computer. You will use these codes (a cheat sheet for the letters will be given to you.) Also, here is a
grid that shows the values, which are especially useful for creating larger numbers.

As you can see, adding the numbers together with 1’s in the columns equal the number at the end.
Here is an example message to get you started. After you figure out this message, create your own and
trade it with your classmates to learn how to decipher the code better.
Example:
01000010 01101001 01101110 01100001 01110010 01111001 01101001 01110011 01100110
