This learning resource is focused on teaching students to calculate and interpret the Average Rate of Change (AROC) using culturally relevant data, particularly in the context of Black History Month and the Chicago South Side. It introduces the core concept of AROC, characterized by the formula (y₂ - y₁) / (x₂ - x₁), which measures the average change in a quantity over a specified interval. The document includes definitions of key vocabulary such as 'interval' and 'slope', provides a worked example of social media growth for a digital artist in Chicago, and presents guided practice scenarios including voter registration and local business revenue growth. Students will engage in independent practice to analyze the follower growth of local artists and examine historical data from the Civil Rights Movement. The exit ticket prompts reflection on the implications of AROC in measuring community growth and the significance of resilience and persistence in social movements.
