This Instructional Activity is a part of the Lesson 1, Unit 4, Grade 7. In this activity, students can leverage their recent work on creating scale drawings to make connections between the dimensions of a different sized flag and the ratio of the side lengths. A note about flag dimensions: The official government flag has sides with ratio 1:1.9, i.e., the width of the flag is 1.9 times its height. However, many commercially sold flags use different ratios. This activity is working with the official ratio.
