SAT Math Lesson Plan 28: Coordinate Geometry

In SAT Math Lesson 28, students explore how coordinate geometry applies to real-world contexts such as architecture, navigation, and design. This lesson covers:

• Plotting and interpreting points in rectangular and polar coordinate systems,
• Using the midpoint and distance formulas to analyze layouts and structures,
• Modeling geometric situations using spatial reasoning, and
• Estimating real-world distances, including arc length on a sphere using great-circle geometry.

Through step-by-step examples and applied problem-solving, students learn how coordinate-based methods can be used to design buildings, place objects precisely, and convert between coordinate formats. This lesson aligns with high school geometry standards and reflects the type of spatial modeling problems that often appear on the SAT.
