The students created a map on their classroom wall showing the origins of their families, connecting colored strings from grandparents' hometowns in various countries to the students' four hometowns. The map revealed that half of the French students' families came from abroad, from countries like Italy, Germany, and North Africa, showing France has long been an immigrant nation. In contrast, the Polish students' families were all native to Poland, and the same was true for most Norwegian and Southern Italian students, though those countries have recently seen more immigration from Africa. Creating the map helped the students understand how migration has interconnected the peoples and histories of different European countries.
