Overview

**Question of the Day: How can we use parameters to give the computer more specific instructions?** In this lesson, students continue to develop a familiarity with Game Lab by manipulating the width and height of the shapes they use to draw. The lesson kicks off with a discussion that connects expanded block functionality (e.g. different sized shapes) with the need for more block inputs, or "parameters." Finally, the class learns to draw with versions of ellipse() and rect() that include width and height parameters and to use the background() block.

Vocab

• Parameter - An extra piece of information passed to a function to customize it for a specific need

New Code
