CS Unplugged: Sorting Networks

Use the Sorting Networks! offline activity to explore how a number of computers can be networked to complete a task faster than a single computer. Students in groups are the 'network of computers' and sort random numbers into order. The task combines knowledge of place value in number and computation in computer science. Support your teaching and learning with video clips and other related resources.
