You’ll start simply: One mirror and simply-arranged targets. But pretty soon you’re getting good, so we’ll up the challenge. More mirrors; targets in surprising and challenging locations. Finish up by designing a challenge for your classmates!
Visualizing, feedback that shows you the consequences of your thinking, opportunities to revise and to challenge yourself and others…these are things that make for a great Friday Fave.
