This product includes all of my Unit 3: Stratification notes (on PowerPoint) for my high school Sociology course. Unit 3 consists of the following sections: systems of stratification (the caste system, slavery, etc.), social classes in the United States, and social mobility. The PowerPoint is broken into larger sections and each section is broken down into smaller subsections so I do not overload my students with too many notes in a single class period. I also provide some statistics in regards to social stratification within the United States; although, this information needs to be updated every few years.
