1) The document provides lesson materials on scale drawings, including examples of scale drawings that are reductions or enlargements of original images. It discusses using scale drawings of maps and geometric shapes. 2) Students are asked to identify corresponding points on scale drawings of maps and the coordinates of vertices for geometric shapes. They are also asked to determine if a constant of proportionality exists for scale drawings. 3) The lesson aims to help students understand how to relate scale drawings to ratios and rates by analyzing examples of scale drawings and their relationships to original images.
