University of Canterbury: Cs Unplugged: Image Representation

This unit introduces learners to some of the building blocks of how computers work without using a computer at all. The lessons keep students actively involved in communication, problem solving, creativity, and thinking skills in...

With this activity, educators can teach the binary system to anyone who can count. Using this approach, many adults are also excited when they finally understand what bits and bytes really are.

Explore the main algorithms that are used as the basis for keyword searching on computers, using different variations on the game of battleships.

Many clever algorithms have been devised for sorting values into order efficiently. In this activity students compare different algorithms to sort weights to simulate how computers devise sorted lists.
