Sum and Difference Identities
Students use sum and difference identities to find exact trigonometric values and simplify expressions.
Key Questions
- Analyze how sum and difference identities allow for the calculation of exact trigonometric values for non-special angles.
- Construct simplified trigonometric expressions using the sum and difference identities.
- Justify the application of these identities in solving complex trigonometric problems.

Planning templates for Mathematics
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.
