In this unit students expand their experiences with multiplication and division by representing the relationship between quantitative variables as a best-fit line on a point graph and in a data table. Students first review the use of the coordinate plane to locate points on a map and look for linear patterns. Treasure maps, scale maps and a story about lost ships create the context for these experiences. Students then use the best-fit line, tables, and reasoning strategies to measure and solve problems about the mass of objects.
