Print and cutout the following images and then you can use them to help you learn your way around the unit circle. Ask yourself questions like, "Where is 7π/6?", then make a guess and then use seven of the π/6 size wedges to see if you are correct. Don't forget to place the wedges right next to each other with no overlap and start them from the positive x-axis and measure counter-clockwise for positive angles and clockwise for negative angles.
