Exact Trigonometric Values
Students will learn and apply exact trigonometric values for 0°, 30°, 45°, 60°, and 90° without a calculator.
Key Questions
- Explain how to derive the exact trigonometric values using special right-angled triangles.
- Compare the exact values with calculator approximations for specific angles.
- Construct a method for remembering the exact trigonometric values.

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.
