IM Grade 8 Math: Unit 2 - Dilations, Similarity, and Introducing Slope

In this unit, students learn to understand and use the term “dilation,” and to recognize that a dilation is determined by a point called the “center” and a number called the “scale factor.” To learn more about how to use GeoGebra’s fully digital and interactive curriculum, visit our IM 6–8 Math page.
