Teacher's field guide

What Students Need to Do: Students graph the share of the world's population living in cities over time. They describe the increase and explain it using migration, city population growth, and the spread of built-up areas.
What Mastery Looks Like: A student labels time and percent on the correct axes and plots the data accurately. They explain that the urban share rose, not just the number of city residents, and give a reason for the change.
Common Misconceptions: Students may graph the number of city residents when the data shows a percentage. Some think urban growth happens only when people move from farms to cities. Others assume every country is urbanizing at the same rate.
How to Assess It: Give students two data points: 30% of the world lived in urban areas in 1950 and 56% in 2020. Ask them to plot both points, describe the change, and name one reason for it.

Lesson moves

Give pairs a data strip for 1950, 2000, and 2020, then have them draw a line graph with labeled axes.
Ask students to write why a farm family might move to a city and how a city could grow without newcomers.
Read three city-growth scenarios; have groups hold up cards labeled migration, births, or boundary expansion.
Compare two dated images of a nearby city in Google Earth Timelapse, then circle land that changed from fields to buildings.
