In this activity, students are introduced to the role of a mapmaker in the year 1754, focusing on the coastline of the Atlantic Ocean where the thirteen colonies were established. The mapmaker, Elias, guides students in tracing and marking the coastline, using blue markers to delineate land from sea. Students learn to identify key areas where colonies were built, ensuring they understand the geographical significance of these locations. Additionally, they are tasked with reflecting on the importance of establishing the first colonies near the Atlantic Ocean, enhancing their understanding of geographical and historical context.
