This Instructional Activity is a part of the Lesson 12, Unit 4, Grade 7. Given a scale factor as a percent, students make a scale drawing of a picture or geometric figure using that scale, recognizing that the enlarged or reduced distances in a scale drawing are proportional to the corresponding distances in the original picture. Given a scale drawing, students identified the scale factor as the constant of proportionality. Students calculate the actual lengths and areas of objects in the scale drawing by using the scale factor.
