SAT Math Lesson Plan 22: Modeling with Functions

In SAT Math Lesson 22, students will learn how to interpret, construct, and apply mathematical models using functions. This lesson covers:

• Using linear, quadratic, and exponential functions to model real-world situations,
• Interpreting parameters and variables in function models,
• Comparing different types of functions to determine the best fit, and
• Translating verbal descriptions into algebraic function models.

The lesson provides clear, step-by-step instruction with worked examples that show how to build and analyze models in business, science, and everyday contexts. Students will gain confidence identifying appropriate function types and interpreting the meaning of key quantities, a frequent focus on the SAT Math section. By the end of the lesson, students will be better equipped to solve modeling problems involving real-world data.
