Unit 4, Lesson 2# Part of a Whole as a Percent

EngageNY 45 min(s)

Students understand that the whole is 100% and use the formula Part = Percent × Whole to problem-solve when given two terms out of three from the part, whole, and percent. Students solve word problems involving percent using expressions, equations, and numeric and visual models. This lesson serves as an introduction to general percent problems by considering problems of which a part of a whole is represented as a percent of the whole. Students solve percent problems using visual models and proportional reasoning and then make connections to solving percent problems using numeric and algebraic methods.
