Exponential Functions: Growth and Decay
Students will understand the characteristics of exponential growth and decay, and their real-world applications.
Key Questions
- Explain how the base of an exponential function determines the rate of change in a system.
- Compare and contrast exponential growth and decay models using graphical representations.
- Predict the long-term behavior of a population or investment using an exponential model.

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.
