Lesson 4 Summary

David Thompson is one of the world’s greatest explorers and cartographers (map makers). He arrived at Hudson Bay at the age of 14 and spent 28 years of his life exploring and mapping almost one-sixth of North America. His maps have been used for more than 200 years!

In this lesson you explored problems involving scale. Maps are just one of the many contexts in which scale is an essential component. In addition to scale, you reviewed converting between units and using proportions.
