08 Assessment & DIRT Lesson

$3.79

(0)

This is the assessment related to the unit of work on encryption. There is an associated DIRT lesson that follows the assessment and a tracker to check class achievement. Grades are related to approximate achievement expected by a year 7 group and should be amended or differentiated for other year groups. The assessment includes practical decryption activities, multiple choice questions and explain/describe questions as well as state / identify questions.

05 Playfair Cipher

$2.53

(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.

04 Pig Pen Cipher

$2.53

(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.

03 Random Substitution Cipher

$2.53

(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.

02 Caesar Cipher

$2.53

(0)

This lesson builds on the first lesson about Morse Code, and challenges students to think about the reason why encryption is needed and then asks them to use a Caesar Cipher to code and decode secret messages.

01 Morse Code

$2.53

(0)

This lesson is the first of a sequence of lessons that challenge students to consider how plain English can be coded or ciphered. It builds on understanding of what Morse Code is used for and students have to cipher and decipher messages themselves. it is an introduction to a unit of work on ciphers and encryption.
