This Instructional Activity is a part of the Lesson 2, Unit 4, Grade 7. 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.
