Introduction to Trigonometric Ratios (SOH CAH TOA)
Defining sine, cosine, and tangent ratios and using them to find unknown sides in right-angled triangles.
Key Questions
- Explain why the ratios of side lengths in a right-angled triangle remain constant for a given angle regardless of the triangle size.
- Differentiate between the opposite, adjacent, and hypotenuse sides relative to a given angle.
- Construct a mnemonic device to remember the SOH CAH TOA ratios.

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.
