Big Concept: Trigonometric Functions
Topic: Unit Circle
Bloom's Taxonomy: understand
Learning Goal: Describe sine and cosine as the motion of a point around a circle and relate angle to position
Key Learning Points: rotation, motion on circle, coordinate meaning
Note: Assess use of motion-based explanation and whether misconceptions (e.g., angles as static values rather than rotation) are addressed
