CS Unplugged: Divide and Conquer
Use Santa’s Dirty Socks book or video to explore the problem of finding a hidden item in one of 1024 items. This problem uses the strategy, divide and conquer; half of the items can be eliminated each time, making the task faster and easier to complete. Relate the task to the way a computer searches. Support your teaching and learning with video clips and other related resources.
