### 2.2 Extension--Murals and Proportionality

by Kevin Hall
When enlarging a picture to make a mural, should you multiply each dimension by a given amount, or add the given amount to each dimension? Students try using both methods to enlarge a simple picture and discover that multiplying keeps the shapes in the picture proportional. This is a practical application of the equivalent fractions method discovered in Lesson 2.1. (If a group finishes 2.2 early, and has ALREADY mastered the 2.1 Flashcards, then this extension is for them.)
