This document contains notes from a math lesson on unit rate as a scale factor. It includes examples of using scale factors to determine measurements for scaled drawings. The key points are that scale factor is calculated as the ratio of actual to drawn measurements, scale factors greater than 1 enlarge a drawing while factors less than 1 reduce it, and scale factors can be used to find dimensions for scaled objects and maps using proportions. Homework includes problem set questions and creating a scaled drawing.
