1. Your Mission Objectives
What Be aware of what binary code is. Why Be able to convert binary to letters. How Active Participators.

2. How do computers work?
A Computer is ran by a CPU (Central processing unit), it’s kind of like the computer’s brain. The CPU has lots of little switches in it that can either be ON (a 1) or OFF (a 0)

3. What is Binary Code?
Binary code is the only thing the CPU understands. Everything you put into a computer is converted to Binary code for the CPU to process. Binary code is made up of 1’s and 0’s. The computer then translates these 1’s and 0’s into everything else. Even images your see are made up of 1’s and 0’s
Read to students to make them understand why we are doing this. You could like this to the matrix and the green 1s and 0s you see.

4. Binary message sent by Bond
This is the message sent by Jame Bond, the students are going to see if they can crack it. Show them the next few slides to explain how to solve the binary code.

5. Mathematics How to crack the code 16 8 4 2 1
If computers only understand 0’s and 1’s how does it make all the other numbers and letter? 16 8 4 2 1 1 =1
1 = A 2 = B 3 = C

6. Mathematics How to crack the code 16 8 4 2 1 1 1 1 =141 1 1
=14
1 = A 2 = B 3 = C

7. Activity
Open the “Crack the code” Spreadsheet found in: Section 3 There is a help sheet and a cheat sheet but only use those if you are struggling. Once you have worked out the secret code do the extra task on the next slide
The crack the code spreadsheet is for students to complete independently.
