This Instructional Activity is a part of the Lesson 3, Unit 2, Grade 8. In this activity, students continue to apply dilations without a grid. Unlike in the previous activity, the dilated images of the points are not plotted. So rather than identifying the correct point, they will need to find an appropriate way to take measurements, most likely with the aid of a ruler or the edge of an index card. Different students will work with different scale factors and will produce perspective drawings of a box. Watch for students who pick a point close to one vertex of the given rectangle.
