This resource contains a series of card tricks. Each trick is presented in two parts. In the first part enough detail is given so that the trick can be performed. A description of the desired effect is given followed by an explanation of the mechanics of the trick – actually what is done to ensure the trick works...

The Magic of Computer Science II begins with an introduction to the resource, explaining the basic concepts used in the book. There follows descriptions of how to perform seven tricks with explanations of how the trick works and the computer science concepts illustrated in the tricks.

The joker in...

Our society is linked by many networks: telephone networks, utility supply networks, computer networks, and road networks. For a particular network there is usually some choice about where the roads, cables, or radio links can be placed. This resource explores the need to find ways of efficiently linking objects in...

When there are a lot of people using one resource, such as cars using roads, or messages getting through the Internet, there is the possibility of “deadlock”. A way of working cooperatively is needed to avoid this happening. The resource begins with instructions on how to play the orange game. The activity contains...

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.
