In this lesson, students will be observing and analyzing primary source images of child laborers taken by Lewis Hine through a gallery walk. From the images, students will make inferences as to what is occurring in images and then use these inferences to describe the Great Depression and the conditions that the children worked in. After students have described the conditions with one another, the students will vote to make a decision about which job they believe was the most harsh. Lewis Hine was hired as a freelance photographer by the National Child Labor Committee. In his work, Hine captured images of children working in mills, factories, mines, and fields to convey the need of child labor laws.
