This lesson introduces the concept of a variable by discussing X, Y, and Heading. Students will explore the coordinate grid and learn how to move sketches by changing the X and Y, both directly and in scripts. The slider and joystick will be used to change X, Y, and Heading. The lesson's activity will be to make many sketches move around the screen with sliders and the joystick.
