Why does an image become distorted when you enlarge just the width? What would a model of the Statue of Liberty look like if you shrunk just the dimensions of her height and not her width? The answers to these questions are based on the concept of scale factors. In the document, Scale Factors, students will explore and apply the concept of scale factors by finding the ratio of the lengths on a model or drawing to the corresponding length of the original object.

Throughout this document students will identify scale factors, use scales to find scale factors, and convert units to the same unit of measure before calculating the scale factor. This document will get your students thinking about the relationship between real life objects and the scale models they may see in the stores or museums.
