Modeling with Exponential Growth and Decay
Students apply exponential functions to model real-world scenarios such as population growth, radioactive decay, and compound interest.
Key Questions
- Explain how to determine if a situation is better modeled by a discrete or continuous growth rate.
- Design an exponential model to represent a given real-world growth or decay scenario.
- Compare the long-term outcomes of two exponential models with different initial values or growth factors.

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.
