Section Title  Primary information  Description and Notes  Suggested resources 

Lesson Length  The expected lesson length will be approximately one hour 
Some variation possible. Assessment Level 1 

Students  The lesson is suitable for KS3 and KS4 students  Since this is a new specification, the lesson is suitable for Year 7 to 9 students and differentiated by outcome  
Overall Focus  This lesson is a continuing look at binary patterns 
Students should be able to understand some of the basic principles of binary and be introduced to the ways that it works. They can then apply this knowledge to practical applications. 
Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 
Key words  logic, statements, Boolean, conditional, binary  These words need to be reinforced throughout the series of lessons  
Assessment  represent numbers using binary patterns 
Evidence here will be student's own work and assessor observations. 

Key Questions  Some questions to get learners thinking about the topics  Some questions about how to understand binary patterns and binary functions in a wider sense  How can you work out an 8 bit binary pattern? What system will help you to work these systems out? What is a realworld application of this method? 
Learning Objectives 

Students need to show that they understand binary and can interpret when it is used and why 
If you are using the Learning Machine learning system, students can add their comments and material to this site as evidence of their growing understanding. The site, if used consistently, will show progression via charts of activity and outcomes. 
Teaching and Learning Elements 


One real world application of binary that students use every day, is the Internet. The Internet is a network of billions of computers. Each computer has a 32 bit address which is a binary address consisting of 4 X 8 bits. Each of the 4 blocks adds up to 255 (8 bits makes 256 variations, but you need to include 0). The main internet system, IP v4, uses this address system which gives 4.3 billion addresses. Looking here, there are now billions of web sites (so computers), so IP v6 is now being phased in which gives 3.4 x 10^38 possible addresses (that is a 'trilliontrilliontrillion'; undecillion' is an obscure term that describes this impossibly large number). This site has an interface to let you translate different elements into their binary equivalent. The BBC also has some good working examples and graphics to explain binary clearly. This game is also quite useful from Cisco. 
Lesson Structure  Possible structure 

The Internet carries binary signals which are translated at either end by various devices. This has opened up a huge amount of ways to use this data. The graphic above is a VOIP (Voice Over IP) telephone which allows you to call all over the world for very little money. Students need to understand that binary carries everything: voice, video, text, etc. 
Homework  Students can make some comments on their blog or ePortfolio about what they think binary is with some clear examples.  Students can vary their homework depending on their level of understanding  Students can continue to document their experience on their portfolio system for assessment
