Sets the scene and introduces students to different types of ciphers

### Learning Objectives

• • Be familiar with ciphers such as Substitution, Transposition and Pigpen ciphers. • Understand the need for information to be encrypted. • Encrypt and decrypt messages using simple ciphers.

### Guiding Ideas

Breakout is an off-shoot of the popular escape room game in which players are willingly locked in a room and, by searching for clues and completing a series of challenges, race against time to ‘break out’. Using OneNote, students decipher messages to reveal codes that enable them to progress through a series of locked rooms in Minecraft.

### Student Activities

Starter (10 mins)

To begin the lesson, load The Secret of Cipher Cove PowerPoint presentation and go through the example ciphers with the class.

Challenge 1 The Secret of Cipher Cove (30 mins)

Split the class into small groups and ask them to load Minecraft Education Edition on their devices and open the Secret of Cipher Cove map. Challenge students to find the secret base by solving the clues in the map. Encourage students to use the OneNote, provided, to help them complete the challenge.

Plenary ( mins)

In the final part of the lesson, ask a member from each team to describe one of the ciphers they encountered in the game and explain how they were able to solve it.

Ask students why they think we need to encrypt information. Try to draw out answers such as: ‘To secure sensitive data such as credit card details when submitting them through websites’ or ‘To protect personal data when storing / transmitting via the web’ etc.

### Performance Expectations

• Were the students able to correctly decode the ciphertext for each challenge?

• Were the students able to explain how a Caesar Shift cipher works?

• Were students able to create their own coded message using a simple substitution or transposition cipher?
