7.G.A.1

Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

Given the dimensions of an object, produce a scale drawing. Given a scale drawing of an object, how big is the original? Relate scale drawings to area. For example: Polygon Q is polygon P, drawn at a scale of 1/2. Polygon Q has what fraction of the area of polygon P? Start this lesson by giving your students this challenge. Conclude by giving this one.
