This lesson builds on students’ understanding of proportional relationships on maps and scale drawings. Students will use scale and proportional reasoning to compute distances on maps and scale drawings. This builds toward solving problems involving scale drawings of geometric figures, including computing actual lengths and areas, and reproducing a scale drawing at a different scale. Big Ideas: Distances on a map are proportional to actual distances and can be computed using the map scale. Note: In this lesson, maps and drawings are not to scale. Vocabulary: map scale, proportional
