Unit Circle Worksheet

1. Watch a short animation or video of a person doing something.

2. Use a blank unit circle diagram to:

   • Label 0°, 90°, 180°, 270°, 360° on the solid lines in the circle and their radian equivalents on the dashed lines.

   • Use one of the clips below. Mark a user’s motion estimate (e.g., “Brushing = ~120°”) on the circle. 

Checklist

• I watched at least 2 clips of tasks. 

• I labeled all key angles on the unit circle (degrees/radians).

• I marked the user’s motion on the circle.

• I wrote a brief explanation about how the unit circle helps us describe motion.
