This is the third lesson on the California gold rush in a unit of five. It could be used independently though if students already have some prior knowledge of the subject. In this lesson students will learn about San Francisco's population boom in 1850, after statehood and word of gold had spread around the world. They will write a persuasive letter from the perspective of a teenager living in 1850 to their parents, explaining why they must leave home and move to California. These Lesson Plans include the history and facts you need, a task sheet with the rubric, stationary for the activity, and images to support the lesson.
