Modeling with Exponential Growth and Decay
Students will apply exponential functions to model real-world scenarios such as population growth, radioactive decay, and financial investments.
Key Questions
- Construct an exponential model to represent a given growth or decay scenario.
- Analyze the parameters of an exponential model (initial amount, growth/decay rate) and their real-world meaning.
- Predict future values or time to reach a certain value using exponential models.

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.
