Learning Objective

Students will calculate the percent of a number using multiple strategies (benchmark percents, decimal multiplication, and fraction conversion) and apply these skills to real-world contexts.

Lesson Overview

Students progress from benchmark percents (50%, 10%, 1%) to complex multi-step percent problems using a variety of real-world contexts. Each task changes exactly one variable to build procedural fluency and conceptual understanding simultaneously.
