03 Random Substitution Cipher

$4.50

(0)

This is the third lesson in a series of lessons about ciphers and encryption. In this lesson, students consider why a simple cipher such as the Caesar cipher is inappropriate for internet encryption and look at a more complex cipher method. They are also introduced to the world of code breakers during World War II and the work of Alan Turing.

04 Pig Pen Cipher

$4.50

(0)

This is the fourth lesson in a sequence of lessons about encryption and cipher techniques. The pig pen cipher is a technique mainly developed by freemasons to code messages to each other. Students will investigate how the technique works and reflect on its effectiveness.

05 Playfair Cipher

$4.50

(0)

The fifth lesson in a sequence of lessons that challenge students to think about different ways that plain text can be converted, encrypted or coded into cipher text. This lesson introduces the Playfair cipher. This is a more challenging lesson to think about than the previous lessons and may need to be significantly differentiated for younger or students with additional educational needs.

Data Representation

$44.96Save 39%

17 Resources

A collection of lesson plans that cover the GCSE Specification for Pearson Edexcel Computer Science but that have been differentiated for key stage 3 introduction to data representation. All are complete lessons with learning mats (LM) worksheets, and lesson plans (LP). LM are provided in PPTX, PPT and PDF format. LP are provided in PPTX, PPT and PPS format. Note that PPT files may lose some functionality. The lessons take the students on a journey with plenty of recap opportunities to consolidate learning, and a range of learning and teaching activities. Lessons generally do not need computer access, so this unit of work is suitable for cover lessons. There are teacher’s notes which also help to make the lesson appropriate for non-specialist or second subject teachers.
