Binary Code Teacher Notes
Objectives/outcomes
Understand why computers/electronics use binary.
To convert binary code to denary numbers (decimal numbers) and visa versa.
Pupils will need access to the Binary Code Activity Pack and the Internet for some of the activities below and to watch the video tutorials.

Why teach Binary?
It is important for pupils to understand how computers translate the things we put into them. Understanding that computers and electronic devices only use a sequence of on and off enables pupils to get to the heart of how computers work. Binary is also excellent for mental maths skills involving addition.

Teacher Input
You could start the lesson by watching the first video in the Pupil Activity Pack. Talk about some of the main parts fo the video, such as the use of on/off being a string of zeros and ones. The video demonstrates how a computer converts a decimal/denary numbers into binary. You could go over another few examples as a class.
Pupil Activities
In the activity pack, there are two video tutorials and two links to websites with free online activities. The first one is a Tetrisstyle game where pupils have to put the binary number for a decimal number or visa versa to remove the rows before it gets to the top.
The second game is a little more challenging because pupils need to find the binary code of different decimal numbers on a grid or zeros and ones. There is a class mode (free play) and timed mode.

Assessment
We have created a binary challenge sheet below for pupils to show their knowledge of converting decimal numbers to binary and visa versa. The PDF also includes the teacher answer sheet.
