Lesson Plan: Rates, Units, and Conversions

This 45-minute SAT Math lesson focuses on solving problems involving unit rates, dimensional analysis, and unit conversions. Students will learn how to calculate speed, cost per item, and population density, as well as how to convert between units using proportion and dimensional analysis. The lesson also includes multi-step word problems that combine rate calculations with percent-based reasoning—realistic scenarios frequently tested on the SAT. These concepts fall under the Problem Solving and Data Analysis domain, which accounts for approximately 29% of the SAT Math section. Students will work through a structured Warm Up, seven detailed instructional examples, a five-problem Review (with additional multi-step challenges), and a 10-question SAT-style quiz with a full answer key. This lesson is part of a comprehensive 35-lesson series designed to build confidence and fluency with core SAT Math skills.
