This lesson introduces students to the process they will use to design programs of their own throughout this unit. This process is centered around a project guide that asks students to sketch out their screens, identify elements of the Circuit Playground to be used, define variables, and describe events before they begin programming (a process very similar to the Game Design Process that students used in Unit 3). Students begin by playing a tug o' war style game where the code is hidden. They discuss what they think the board components, events, and variables would need to be to make the program. Then, they are then given a completed project guide that shows one way to implement the project, and are walked through this process in a series of levels. At the end of the lesson, students have an opportunity to make improvements to the program to make it their own.
