Unit 6: Scaling Up- Dilations, Similarity and Proportional Relationships
Lesson 2 of 6

Objective: Students will understand how dilating a shape affects the perimeter and area of the figure. Students will be able to describe the relationship between the perimeter or area of an image under dilation and the perimeter or area of the pre-image using an equation or a verbal rule. Students will understand what it means to ‘make sense of problems and persevere in solving them’. Students will be able to explain their reasoning about a non-standard problem and critique the reasoning of others.

Big Idea: Students learn how dilating a shape affects perimeter and area as they design a sign large enough to show up on Google Earth.
