Grade 7 Mathematics Module 1, Topic D, Overview

Studying for Test

In Topic D, students bring the sum of their experience with proportional relationships to the context of scale drawings (7.RP.2b, 7.G.1).  Given a scale drawing, students rely on their background in working with side lengths and areas of polygons (6.G.1, 6.G.3) as they identify the scale factor as the constant of proportionality, calculate the actual lengths and areas of objects in the drawing, and create their own scale drawings of a two-dimensional view of a room or building.  The topic culminates with a two-day experience of students creating a new scale drawing by changing the scale of an existing drawing.
