This Instructional Activity is a part of the Lesson 6, Unit 3, Grade 8. Students learn the multiplicative effect of scale factor on a point. Note that this effect holds when the center of dilation is the origin. In this lesson, the center of any dilation used is always assumed to be (0, 0). Show the diagram below, and ask students to look at and write or share a claim about the effect that dilation has on the coordinates of dilated points.
