Modeling with Sinusoidal Functions
Using sinusoidal functions to model real-world periodic phenomena such as tides, temperatures, and sound waves.
Key Questions
- Why are sinusoidal functions the preferred tool for modeling sound and light waves?
- Evaluate the accuracy and limitations of a sinusoidal model for a given real-world data set.
- Predict future values of a periodic phenomenon based on its sinusoidal model.

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.
