Module Overview

This week will be largely devoted to the Use Template strategy, which is the design recipe you will use most often in this course. We will also talk about the Divide Into Cases strategy, about testing, and give you a checklist for reviewing and polishing your program before you turn it in. This completes our survey of the Function Design Recipe. You will also review Racket's facilities for producing images and scenes.
