Title: Computer Science Fundamentals Unit 4 Course C Lesson 16: Binary Bracelets (2018)

Binary is extremely important in the world of computers. The majority of computers today store all sorts of information in binary form. This lesson helps demonstrate how it is possible to take something from real life and translate it into a series of "ons" and "offs".

In this lesson, students will learn how information is represented in a way such that a computer can interpret and store it. When learning binary, students will have the opportunity to write codes and share them with peers as secret messages. This can then be related back to how computers read a program, translate it to binary, use the information in some way, then reply back in a way humans can understand. For example, when we type a sentence into a document then press save, a computer translates the sentence into binary, stores the information, then posts a message indicating the document has been saved.

Students will be able to:
- encode letters into binary.
- decode binary back to letters.
- relate the idea of storing letters on paper to the idea of storing information in a computer.
