Exploratory Challenge: Reflection on Scale Drawings

This Instructional Activity is a part of the Lesson 22, Unit 1, Grade 7. Ask students to take out the original scale drawing and new scale drawing of their dream rooms they completed as part of the Problem Sets from Lessons 20 and 21. Have students discuss their answers with a partner. Discuss as a class: How are the two drawings alike? How are the two drawings different? What is the scale factor of the new scale drawing to the original scale drawing?
