Cryptography

Since man first began writing there has been a desire to send messages in secret: in code.  Codes and ciphers are forms of secret communication. A code replaces words with letters, numbers or symbols.  A cipher rearranges letters or uses substitutes to disguise the message. This process is called encryption. The art of writing and solving codes and ciphers is called cryptography.

Codes and ciphers have been used throughout time when people wanted to keep messages private.  Cryptography has, and is still, used by governments, military, companies, and organisations to protect information and messages.

Today, encryption is used to protect data and data transfer between computers.  Documents, data and messages are encrypted to protect confidentiality.  Modern encryption methods are very clever but their underlying principles remain that of those ancient methods.

Cryptography Unit

I have written a 6 week unit introducing cryptography for iCompute for Primary Schools computing scheme of work.  Here, the children will unleash their inner spy and learn about how data can be transferred in secret over distances. They will learn how codes and ciphers have been used throughout history and explore a number of different ways that data can be encrypted and decrypted.

As part of it, along with step-by-step lesson plans and pupil/teacher support materials, I’ve been putting together resources on the history of cryptography.  Download a brief introduction to the Enigma machine and how the magnificent men and women at Bletchley helped shorten World War II with their code breaking skills!  Practise secret code writing in your classroom by downloading and making a cipher disk and transmitting messages by Morse Code using a Morse Decoder Wheel.  Lots of engaging activities to learn about encryption methods past and present and the importance of keeping data private in the modern digital age.

The new cryptography unit – iCrypto – is available now in our Whole School Computing Curriculum for the National Curriculum for Computing at Key Stage 2.

Cross Curricular Computing Lesson Plans

Enrich learning with a cross curricular approach to primary computing

Computing is one of the most fundamentally cross curricular subject areas in education.  It’s about using technology, logic, creativity and computational thinking to solve problems that cross all disciplines.  It requires the systematic breakdown (decomposition) of both the problem and the solution.  We need to prepare pupils for how to live in an increasingly digital world by equipping them with the knowledge, understanding and skills to solve as yet unknown problems using tools and technologies that do not yet exist.  We can work towards achieving this by using computing as a means of making sense of the world and using what the children learn in computing across the curriculum.

The best primary practice includes a blend of rigorous, discrete, subject teaching and equally effective cross curricular links.  Both approaches are needed for effective learning to take place, to enable children to make links between subjects and to set learning in meaningful contexts.  Using computing throughout the primary curriculum offers a way to enrich and deepen learning through engaging, interconnected, topics.

I have put together a selection of free resources and links to others to help teachers get started with ideas and inspiration for enriching learning and exploring computing through a rich variety of media and technologies in cross curricular contexts.

Free Valentines Day Coding Lesson

Valentines Day – Spreading the Love with Code!

 

Valentines Day

Click to download

Play and code this Valentines day with our free coding activity: a romantic themed Cupid game for pupils aged 7-11 using Scratch.

Throughout the year, I create free themed computing lessons, and I’ve written another step-by-step lesson plan and some teacher/pupil computing resources that I’m using in my computing classes and am adding to iCompute to celebrate Valentines Day.

Love is in the air but Cupid needs a little help aiming his arrow!  Challenge your pupils to program Cupid’s bow to respond to user input and aim to catch the heart of a love interest.

Valentines Day Resource

 

Ideas for differentiation, extension and enrichment are included in the lesson plan.  Plus program templates and partially-written programs for teacher and pupil support. Lots of opportunities to be inspired and get creative!
