Watch as the sprite moves by 5 degrees and calls out its direction. Press the up arrow to move the cat 15 degrees (background will change to indicate key pressed). Or click on the dial to redirect the arrow and have the cat call out its position (background will change to indicate click). (Just don't click and release too fast so the click registers, and don't leave your mouse hovering over the green flag.)
Getting familiar with Scratch. Degrees demonstration for students. (Thanks for Al Sweigart's rotation project for the arrow idea.)
