The Peruvian Coin Flip - Cryptographic Protocols

This activity shows how to accomplish a simple, but nevertheless seemingly impossible task -making a fair random choice by flipping a coin, between two people who don’t necessarily trust each other, and are connected only by a telephone. The resource begins with a detailed explanation of the activity and...

Happy Birthday

In this project, part of the HTML and CSS projects , you’ll be introduced to HTML & CSS by learning how to make your own customised birthday card.

All sorted

Machine learning is a system where rather than a computer programmer deciding the best way to sort, organise, classify or use information, the computer program develops its own set of instructions (algorithm) based on information that users feed it.  Scientists at the University of Oxford are working on ways to...

Network protocols

In this activity students consider how different methods of communication operate successfully. By looking at rules and procedures in place, students are introduced to communication protocols. By working through a role-play scenario, pupils test their own protocol operating in an unreliable environment...

Starting from Scratch

Scratch is widely used in primary schools to teach children basic programming. This resource goes deeper, making use of the familiar Scratch environment to take students deeper into programming concepts such as:

  • Algorithm design
  • Parallel and sequential instructions
  • Event-driven...

Divide and conquer

This activity provides a mathematical problem that is solved in a simple way. It relates to the way algorithms are used in search engines and links to problem solving in maths. The context is that of Santa trying to find his socks in one of 1024 boxes, which a...

What are algorithms?

This resource provides a concise explanation of what an algorithm is, and shows clear examples of how to teach algorithms across the primary curriculum. It also provides ideas for unplugged activities to teach algorithms to children from 4-11 years. Many of which may be found in the...

Teaching problem solving the unplugged way

This resource contains a variety of activities and teacher resources to help students develop their problem solving skills, these are mostly through the use of unplugged activities which also encourage the development of skills associated with creating algorithms. The resources consist of teacher guides for each of...

Ice Roads - Steiner Trees

Sometimes a small, seemingly insignificant, variation in the specification of a problem makes a huge difference in how difficult it is to solve. This activity, like the The Muddy City problem, is about finding short paths through networks....
