Trigonometry and Its Applications · Term 2

Introduction to Trigonometric Ratios

Students will define sine, cosine, and tangent for acute angles in a right-angled triangle.

Key Questions

  1. Explain why trigonometric ratios are constant for a given angle regardless of triangle size.
  2. Differentiate between the opposite, adjacent, and hypotenuse sides relative to an angle.
  3. Construct a right-angled triangle and label its sides to determine trigonometric ratios.

lesson plan

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 planner

Math 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.

rubric

Math 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.
