Unit 5: Writing and comparing ratios
Lesson 7 of 14

Objective: SWBAT explain the concept of "building up" a ratio pattern as a model for making equivalent fractions in order to make common denominators.

Big Idea: Repeating the same pattern over and over is a concrete model for understanding the abstract process of multiplying the numerator and denominator by a common factor.
