| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

Exponential Growth and Decay
Grade 9
Mathematics
20 students
This lesson aligns with the national standards for mathematics education, specifically focusing on functions and their applications.
| Step Number | Step Title | Length (minutes) | Details |
|---|---|---|---|
| 1 | Introduction | 5 | Introduce the topic of exponential growth and decay. Provide simple definitions and examples. |
| 2 | Real-World Examples | 5 | Discuss real-world applications: population growth, radioactive decay, and interest calculations. |
| 3 | Formula Introduction | 5 | Present the exponential growth and decay formulas: (y = a(1 + r)^t) and (y = a(1 - r)^t). |
| 4 | Guided Practice | 10 | Solve example problems as a class using the formulas. Encourage participation and clarify doubts. |
| 5 | Independent Practice | 5 | Distribute worksheets for students to practice individual problems on exponential functions. |
| 6 | Review and Homework | 5 | Summarize key points of the lesson. Explain homework assignments, which involve further practice problems. |
Homework will consist of additional practice problems focused on exponential growth and decay. It will be collected the following class period and checked for understanding without student presentations.
Informal assessment will occur during guided practice, monitoring student participation and understanding. Homework will be assessed for accuracy and comprehension.
