Students transition from degree measure to radian measure and explore its application to the unit circle. They evaluate trigonometric ratios for angles expressed in radians.
Key Questions
- What is a radian and how does it relate to the arc length of a circle?
- How do we convert between degrees and radians?
- How does the unit circle help us evaluate exact trigonometric ratios?
Planning templates for Advanced Functions
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
