Your Mission Objectives Be able to recognise binary code Be able to convert denary numbers into binary numbers. Be able to convert alphabetical characters in to ASCII. Create a message in ASCII code independently.

What is Binary? Class discussion. VideoVideo Key words: Denary Everyday number system 1,2,3,4,5….. Also called Base-10 ASCII Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or Task 1: Create binary numbers on 1_Binary_Code worksheet. Task 2: Work through the mission with Mr Bond : 2_ Crack_The_Code worksheet Task 3: Load up 3_Binary Game Link and play the game. Extension: Load up 4_Binary Code Student. Be able to recognise binary code Be able to convert denary numbers into binary numbers. Be able to convert alphabetical characters in to ASCII. Create a message in ASCII code independently. Recognise and explain how to convert Denary to Binary. Binary worksheets/ Maths Reflective learner/ Self manager To understand the language that computers use to communicate and process instructions. Load up Binary Game Link and play the game.

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)

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 RESEARCH

How to crack the code = A2 = B3 = C If computers only understand 0’s and 1’s how does it make all the other numbers and letter? =1

How to crack the code = A2 = B3 = C Mathematics =14 ASCII 14 = N

Activity Load up the 1_Binary_Code word document and complete the tasks.

Activity The message is in the video ………….. 2_Crack_The_Code Task

Binary message sent by Bond

The Secret Password is SKYFALL Lets try it out ……

Now test your skills against the Binary Game. Load up “Binary Game Link”“Binary Game Link”

Test your knowledge…. Task : Load up 4_Binary Code student and convert your answers into Binary. Complete as many tasks as you can.

Did you achieve your Mission Objectives Discuss: Discuss with your partner what you now know about Binary numbers.
