This lesson plan introduces 4th grade students to child labor during the Industrial Revolution. Students will learn about the hardships faced by child laborers through primary source documents and images. They will internalize what they've learned by writing a journal entry comparing a child laborer's life to their own. The lesson involves a warm-up activity showing an image of child laborers, reading handouts in groups with discussion, and applying their new understanding through reflective writing assessed with a rubric. Differentiation suggestions include oral presentation of materials and adjusting length for different learner needs.
